What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

Product Strengths

  • Gorgeously finished and solidly made with well-thought-out controls, and high-quality innards
  • Versatile product due to endless permutations with bass controls, and crossover adjustment
  • Provides additional low-end extension without being overly intrusive
  • Counterintuitively effective despite its tiny size
  • Great driver speed, and detailed music reproduction

Product Considerations

  • Bass extension is limited, not suited for bass addicts looking for gobs of deep bass
  • May not be ideal on carpeted floors, better suited for hardwood floors
  • Not really a subwoofer with its relatively small 6.5″ driver
  • Optimizing a sub installation is not for the faint of heart—it requires some real dedication

Takeaway: The REL Tzero MKIII is a great first subwoofer, particularly if you have a small listening space and/or bookshelf speakers. Its diminutive dimensions are effective, and provide a subtle bass boost, enhancing mid-bass reproduction.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Miracle In Miniature

100% REL, Just Smaller

Tzero is, in many ways, the most difficult design we have ever executed because never before have we delivered so much for so little. Five coats of your choice of black or white high gloss lacquer as in all Serie T, NextGen Class D amplifiers, our famous High Level Input, plus a separate .1/LFE input stage with its own volume control to get theatre levels AND music perfect without racing to adjust or looking for a remote control.

The jewel of the MKIII is the new aluminum-coned driver, a rugged 6.5" unit with exceptional output and low bass extension for its size. While it won't drive medium or large rooms hard, we make plenty of larger models that handle that task, Tzero MKIII remains a miracle in miniature

Scaled for the Simple Life

Serie T/9x: Bigger and Better

The T/x Serie Flagship

The job of any range topper for REL is to deliver more of everything, particularly output and dynamics. The 9x is no different in this regard, as it delivers the goods in both music and theatre applications. 9x, however, delivers a level of intimacy, clarity and speed that means there are no longer trade-offs between the sonic balance of smaller models weighed against the power and scale of a model 9.

The all new 9x has even greater output than before, but the headline news is the way it sacrifices nothing in clarity and transparency to achieve this. At this price it opens the pathway for owners of high-performance European floor and stand mounted monitors and smaller panel speakers to enjoy truly full range sound.

Reimagined, Then Reengineered

A completely redesigned flagship

Many don't realize the intense linkage between performance and design here at REL. Performance is everything to us and so it drives physical design revisions. Our engineers, recognizing the need for greater acoustic volume to achieve the goals of greater fluidity and power, turn to the designer who works dimensions to fool the eye into seeing a smaller, more compact footprint even though cabinet volume increases. Using gently rounded corner radii that allows the eye to flow over and see less visual mass. The result is both modern and familiar with no unnecessary adornment.

Outsized Performance

Innovative Alloy/Fibre Bass Engines

To achieve higher output with better control requires a complete overhaul of the suspension components. Much like the suspension on a sports car, these items are responsible for the tuning and feel of our designs. By increasing the cabinet volume, efficiency is improved yielding higher output for no more amplifier power. Less back pressure inside the cabinet means we can tune for a stiffer, better controlled driver suspension. We retained the best aspects of our previous design, such as the aluminum center cap responsible for stiffening the lightweight 10" (250mm) cone while adding almost no mass. The updated combination produces considerably better attack and dynamics with greater transparency.

Tried and True Amplifiers

The Brains Behind the Brawn

We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL's standard setting reliability. The powerful 300 watt mosfet amplifier used in the T/9x remains an icon with huge reserves of current, massive power supplies but small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior strength.

REL's legendary High Level Input connection and fast filters are a significant part of the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character. Unique tuning and special limiters mean the T/x range sounds fresher, faster and more dynamic than before.

Standby Mode switch is only included on 220V units.

Wireless that Doesn't Compress the Sound

Unlimited Possibilities

At REL, we've developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. We never rely upon digital compression as it results in dull, lifeless sound. Instead, we have perfected an (optional) Arrow™ wireless system so fast and dynamic we're comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected conventionally with cable.

REL is widely recognized as the premier audiophile-grade subwoofer manufacturer, focusing exclusively on designing subwoofers that match the speed and clarity of high-end loudspeakers. Their higher-end models are specifically designed to integrate seamlessly with audiophile speakers, enhancing the soundstage and instrument separation rather than simply adding bass impact.

Rethink What's Possible

Performance Home Theater

Serie HT is designed specifically to answer the challenge of creating affordably priced, exceptionally dynamic, pure home theater powered subwoofers. The HT/1205 MKII is the ideal combination of a lightweight, modern 12" CarbonGlas™ (300mm) driver coupled to a powerful 500W Class D amplifier that runs cool, producing extraordinary dynamics. Internally, we developed specially adapted home theater input filters that produce extremely flat bass down in the 20's.

We set out to build the loudest, relatively compact 12" unit available for pure home theater use, and at truly attractive pricing. You'll be the judge of how well we accomplished that goal, but critics are already lining up for reviews. We believe the HT/1205 MKII is destined to become a modern classic with svelte cabinet dimensions finished in an attractive, yet purposeful line grained black aluminum-look and topped by a 12mm thick beautifully polished top that serves to damp vibrations on the critical top surface of the cabinet.

For REL owners already enjoying our Reference, Serie S and T/i subwoofers designed for both 2-channel and theater use, the HT/1205 MKII is designed to supplement their system's .1/LFE output to produce extremely high output for chest rumbling home theater special effects.

Designer Exterior

The beautiful new cabinetry is bespoke; it has new textures, proportions, and finishing touches previously unseen in the category. Lower, sleeker cabinetry borrows proportions drawn from our new Reference models. Over the years, our experiments have established that this results in a faster, deeper presentation of bass—all while looking smashing. Your eye is immediately drawn to the top panel, whose entire surface finished in 5 coats of hand-polished piano black lacquer. A discreet REL logo floats within the top layer of lacquer whilst the body of the cabinet is clad in horizontally streaked, line-grained composite. The entire affair looks expensive, bespoke, and tastefully restrained. Additionally, you can stylishly combine it with either Serie T/x or Serie S in large, fully-immersive REL HT/3D™ setups.*

Drive Like You Mean It

The HT/1205 MK II's driver is a 12" (300mm) CarbonGlas™ construct as it has always been, but all its components were beefed up. It is improved in both large and small ways, enabling it to deliver the greatest performance possible. Lightweight, stiff, and quiet, the combination of glass fibre primary cones with true carbon fibre centre caps results in a cost-effective yet pistonic cone. Larger, more powerful magnets produce more energy. Upgraded suspension designs control the HT/1205 MKII's output all the way out to the limits of both the amplifier and the driver. The result is crazy output, while the HT/1205 MKII remains fast and liquid.

Now Hear This!

Amplifiers do the heavy lifting in a theatre subwoofer. We turned to a true tier one amp supplier to build our latest design for us—they did not disappoint. They included thicker boards, upgraded the power supplies, and did all the stuff that results in a brutally powerful amp with remarkable longevity. Additionally, the MOSFET power modules rated at 800 watts mean this amp is just cruising at its 500-watt rating. It produces truly awe-inspiring sound. While the theatre gets all the headlines, the HT/1205 MKII's big secret is that it sounds sublime in musical applications. Big and robust-sounding, it is sure to become an instant classic.

PerfectFilters™: Where it All Starts – Amplifier

REL input filters are renowned throughout the audio world. They bring together ultra-fast crossovers, elevation filters that extend the flatness of deep bass, and explosive-sounding integrated limiters. This compact series of analogue circuits is REL's secret recipe in both music and film sound. Refined in this second generation, the secondary filters are much higher in frequency; they make the rarefaction of air in the sound of an explosion to feel that much more realistic. Also, our latest circuit includes an all-analogue subsonic filter that begins as low as 8 Hz to minimize the effects of infra-noise from soundtracks that extends well below the resonance point of the driver. The result is incredible delivered power with the ability to play all the way to the driver's limit without distortion.

Wired For Sound: HT-Air

Wired for sound used to entail long runs of cable strewn across the floor. With our optional HT-Air™, great sound has become "un-wired." Wire has been replaced by a tiny transmitter and matching receiver that sends an incredibly fast 5.8Ghz wireless signal up to 60 feet with no digital compression. This affordable circuit includes the same LSIC chip that powers our state-of-the-art AirShip II, minus the expensive analogue-to-digital and digital-to-analogue (DAC) convertors. The HT-Air is perfect for the .1/LFE signals using RCA connectors that are HT/1205 MKII's primary mission.

At 6 dB louder than any previous REL within 50% of its price, the original HT/1205 was a remarkable value.

REL is widely recognized as the premier audiophile-grade subwoofer manufacturer, focusing exclusively on designing subwoofers that match the speed and clarity of high-end loudspeakers. Their higher-end models are specifically designed to integrate seamlessly with audiophile speakers, enhancing the soundstage and instrument separation rather than simply adding bass impact.

Classic 98

Nothing Says Lifestyle like Mid-Century Modern RELs

Classic 98 holds a distinctive place within the REL pantheon. While not a part of any regular line of REL products, instead, it is its very own solution for anyone who owns and loves vintage audio gear, or its modern equivalents that we refer to as retro. With different aspirations, Classic 98 offers a slightly softer touch, delivering a broad carpet of room-filling bass. While it might trade off a touch of the speed, clarity, and deepest bass that our standard models, like the T/9x, are known for, it compensates with its inviting warmth. Classic 98 beckons you to put on a record, pour a cherished drink, recline in a comfortable chair, and relax into the music. Its classic natural walnut veneer and mid-century modern styling complements a wide range of decors. It's also easy to place and use. One reviewer aptly dubbed it as "the audiophile's ultimate guilty pleasure."

Designed to Warm the Heart

A Nod to Iconic Design

Classic 98 channels the essence of our renowned 10" down-firing designs from the late 90s. The rich, natural walnut veneer exudes warmth and authenticity, reminiscent of the mid-century stereo gear. The radiused curve, accentuated by a subtle reveal line, showcases modern craftsmanship while honoring past design. The rear amp panel, with its white gold silk screening and contrasting knobs, evokes memories of the era, while the glossy black logo set against a matte background adds a contemporary touch.

Drive To Survive

The Heart of Classic 98: The 10" down-firing driver, crafted using our traditional paper cone technique, revives the vintage REL sound. This driver, built to handle the abundance of power offered in Classic 98, ensures a sound that's not just powerful, but pure and deeply resonant. While Classic 98 maintains the aesthetics of our historical models, it plays louder and deeper, offering an audio experience that marries the reliability and technology of modern RELs with a retro look and sound.

Paper Cone Mastery: Hot-pressed, lightweight paper forms the outer 2/3 of the cone. The inner cap is a premium air-dried paper that stiffens the driver, allowing Classic 98 to outperform many of our products from the past. A natural butyl surround produces a gentle, period-correct dynamic that endures.

Unlimited Power Used Wisely

Amplifier Excellence: Back in the 90s, offering a 300W amp at an affordable price was a significant challenge. Today, we've harnessed one of our latest amp designs – a high-current, lightning-fast Class D amp. This modern powerhouse is not only dynamic but also stands as a testament to our commitment to delivering top-tier performance without compromising on affordability.

High-Level Connectivity & Filters: We've paired this powerhouse with the High-Level connectivity and modern input filter technology. These filters, with their swift 8ms response, are intuitive and efficient. And if you were wondering about the old, confusing ABC filters, well, some things are best left in the past! To further enhance the experience, we've incorporated unique versions of the LimitLess™ Limiters and Perfect Filters™, ensuring that Classic 98's amplifier is a harmonious blend of the modern and the vintage.

Positioned for Distinctive Excellence

Within the REL product line, Classic 98 carves out its unique niche, priced just beneath the T9/x. While both models stand as paragons of top-tier performance, they cater to distinct experiences. The Classic 98 is designed for aficionados who yearn for the vintage REL sound and styling, offering a nostalgic journey back to the golden age of stereo, yet infused with the advancements and reliability of modern technology.

The T9/x, on the other hand, is the embodiment of power and depth, wrapped in a sleek, modern design. Tailored for those seeking cutting-edge performance, it's a versatile powerhouse adept at delivering both in music and home theatre settings, ensuring a comprehensive sonic experience.

For those with a penchant for pure home theatre applications, our Serie HT is the go-to choice. Crafted for peak .1/LFE performance, it's the epitome of cinematic immersion, ensuring every scene is felt as much as it's seen.

Leading the Charge with Wireless

At the heart of our brand is a commitment to pushing boundaries. Our wireless technology stands as a testament to this, leading the industry in both innovation and performance. We don't just prioritize dynamic range; we ensure it's delivered with zero compression. This dedication results in top-tier sound quality paired with user-friendly operation.

For Classic 98, we're proud to offer two cutting-edge wireless options tailored to diverse needs:

AirShip II—Crafted for our Reference models, AirShip II is a beacon of advanced wireless technology. Operating at 5.8 GHz, it supports both High-Level Connection and .1/LFE, even simultaneously. This ensures peak theatre performance, making it the choice for those who demand the very best.

HT-Air MKII Wireless—A nod to our HT models, the HT-Air MKII offers an elegant and cost-effective wireless solution. Transmitting at 5.8 GHz, it flawlessly conveys either stereo low-level or .1/LFE signals without compression. However, it's worth noting that High-Level Connectivity isn't supported with the HT-Air MKII.

REL is widely recognized as the premier audiophile-grade subwoofer manufacturer, focusing exclusively on designing subwoofers that match the speed and clarity of high-end loudspeakers. Their higher-end models are specifically designed to integrate seamlessly with audiophile speakers, enhancing the soundstage and instrument separation rather than simply adding bass impact.

Filtered for Purity

The Practically Perfect REL

REL's legendary High Level Input connection and fast filters are a significant chapter in the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character and blends seamlessly with your speakers. Unique tuning and special limiters means the T/7x sounds fresher, faster and more dynamic than before.

T/7x is, without reservation, one of the most-balanced RELs of all time. In order to achieve perfect balance, a sub must weigh speed against heft, while ensuring true extension-depth-and do so in a physically harmonious package. T/7x manages to make it all seem easy. Quick and delicate for a perfect blend, it can pound out exceptionally deep, tuneful bass that belies its size and plays louder than most will ever require.

Designed to be Better

Reimagined, Then Reengineered

Many don't realize the intense connection between performance and design here at REL. Performance is everything to us and it leads to physical design solutions. Thus it is, that our engineers, in recognizing the need for greater cabinet volume to achieve the goals of greater fluidity and power, turn to the designer. He works dimensions to fool the eye into seeing a smaller, more compact footprint, even though cabinet volume increases. Using gently rounded corner radii that allows the eye to flow over and see less visual mass. The result is both modern and clean with no unnecessary adornment.

Drive On

INNOVATIVE ALLOY/FIBRE BASS ENGINES

The 8" long throw active and 10" passive drivers are where T/7x derives its incredible speed and clean finish. A thorough revision of critical suspension components are responsible for the agility and suppleness of T/7x. The T/7x sounds louder and more powerful is expected, but few would predict it also is faster, more reactive and transparent than our prior generation, itself a paragon of virtue. Stiffer suspensions better suited to advanced duty mean not only can each driver trace minute details, but also travel farther and handle more power.

Tried and True Amplifiers

The Power Behind REL

We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL's standard setting reliability. The powerful 200-watt mosfet amplifier used in the T/7x remains an icon of sound and reliability with huge reserves of current. Massive power supplies are used and small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior reliability. The best gets better.

Standby Mode switch is only included on 220V units.

Zero Compression Wireless

Unlimited Possibilities

Arrow™ is REL's latest generation of zero compression wireless. Super-fast delivery of both High Level Bass and .1/ LFE ensures the rich, natural warmth that only RELs can deliver. With a throw distance of some 45'(13.7M) Arrow permits flexible placement without sacrificing sound quality.

  • Excellent integration with main speakers, blending seamlessly and extending the bass without overpowering or sounding detached
  • Fast and detailed bass response, allowing it to keep up with fast musical transients and reveal subtle textures in bass notes
  • Enhances the overall soundstage, opening up the width and depth of the image
  • High build quality with quality materials and a premium finish
  • High-level connectivity via a Neutrik Speakon connector, allowing it to take on the sonic characteristics of the amplifier for better integration and timing

Product Considerations

  • Suitable for smaller home theater rooms, it may have limitations for the most demanding movie soundtracks in notably large rooms due to its low-frequency extension
  • Lacks digital signal processing (DSP) and mobile app control, which some users may prefer
  • With certain songs, it may not improve the original bass, and in some cases may 'destroy' the bass texture

Comparisons (according to reviewers)

  • Vs REL Strata III: The T/7x is cleaner, more dynamic, and has faster transients than the Strata III, despite having similar bass extension
  • Vs SVS SB-3000: The REL T/7x blends more naturally with the main speakers and offers greater detail, timbre, and contour in bass frequencies
  • Vs SVS PB-2000 Pro: The SVS PB-2000 Pro offers more air movement
  • Vs JL Audio d108: The JL Audio d108 lacks a speaker-level audio input

Takeaway: The REL T/7x is a great choice for those who want a musical subwoofer that adds detail and space to their audio system. Its ability to integrate well with speakers and provide fast, accurate bass makes it a worthwhile addition to any audiophile setup.

REL
HT/1003 MKII
880
/
Released
2022
Buy an HT/1003 MKII if you either don't have the space or don't require the extra output of our larger models. It's that simple. More compact, just as beautiful, it delivers identical build quality to its siblings. It's style makes it an ideal partner in HT/3D REL theatre setups with Serie T/x. All-new 300W Class D amplifier offers greater headroom and powers a new CarbonGlas™ 10" (250mm) driver. This combination delivers devastating output, playing TWICE as loud as the original. At this price, this performance is unheard of. The icing on the cake is that, like all the new HT's, it responds beautifully when playing music, and HT-Air delivers state of the art (optional) wireless.

SVS
3000 Micro
899
/
Released
2021
The challenges of designing a mini subwoofer capable of chest-pounding output at the lowest frequencies, while maintaining effective thermal and energy management in a micro-sized enclosure, has always been the holy grail of subwoofer brands. Previous designs were flawed with weak output, distortion, and uncontrolled movement of the cabinet itself. 3000 Micro is like a magic trick— small enough to fit anywhere and capable of delivering breathtaking bass from a shockingly compact 10-inch enclosure.
Check Amazon
SVS is a hifi brand known for its subwoofers that feature dual 8-inch voice coils and 17-inch drivers, delivering deep bass with precise control through their force-balanced woofer array design. Their Ultra Evolution series uses diamond-coated aluminum dome tweeters and acoustically centered time alignment cabinet architecture to ensure all sound reaches listeners' ears simultaneously for a coherent soundstage.
Expand Details

Our Summary

Product Strengths

  • Compact size makes it easy to integrate into various rooms and setups
  • Delivers deep and clear bass
  • Powerful amplifier for its size
  • The SVS app allows for easy and precise tuning of the subwoofer
  • Dual opposing drivers cancel out mechanical energy, minimizing cabinet vibration
  • No speaker-level connections, limiting setup options for some stereo systems

Product Considerations

  • Can be expensive compared to other subwoofers with similar output, especially if size is not a primary concern
  • Limited output compared to larger subwoofers, potentially not ideal for large rooms or bass enthusiasts
  • Power cord length can be restrictive when finding optimal placement
  • Woofer placement can be tricky, because the opposing drivers might be too close to side walls depending on placement

Comparisons (according to reviewers)

  • SVS 3000 Micro has better adjustability than Sunfire

Takeaway: The SVS 3000 Micro is a small but capable subwoofer that delivers impressive bass performance for its size, enhanced by a user-friendly app for fine-tuning, and is a great option for those needing a compact solution without sacrificing sound quality. It is small and easy to integrate into a listening room.
