Our take on the brand
.jpeg){kind=small}
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.

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.
