How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Our take on the brand

Axiom Audio manufactures its own drivers and features unique design elements like rear-firing drivers with DSP processing, die-cast metal faceplates that act as heatsinks, and Vortex ports to reduce air turbulence. Their speakers, including the LFR1100 and M100 v4, are known for uncommon features at their price points, such as seven drivers per speaker for greater linearity and the ability to reach exceptionally low frequencies of 15Hz in their subwoofers.

Classic 99

Nothing Continues to Says Lifestyle like Mid-Century Modern RELs

Classic 99 extends our Classic Line to loftier heights. Richer, bolder, and more powerful? Certainly. Yet 99 is also capable of far greater nuance, air, and resolution than its lesser brethren. For those with more capable systems and larger rooms, Classic 99 delivers advances on every front, while still maintaining the same easy-going, room-filling nature all Classic offerings possess. The high-grade genuine dark walnut veneer complements a variety of decors. Classic 99 delivers this in the same simple, comforting form of Mid-Century Modern design. Perfect for those who welcomed the original, yet were waiting for the next chapter to be written, those who crave even higher performance and the ability to fill larger, grander spaces with a broad carpet of deep bass. You'll still want to put on a record, pour a favorite drink, sink into your favorite chair, and relax into the music or movie of your choice. Classic 99, for those who waited for more.

Designed to Be Superior

Classic 99 adopts the form language introduced in its model 98 stablemate. As comfortable as a pair of well-worn loafers, it features solid cabinet walls as thick as 32 mm, clad in rich, warm walnut veneer, hand fitted with care. The simplest of natural aluminum badges and softly radiused feet milled from solid billet, blacked out to allow it to seemingly float, ensure that nothing, not even a grille disturbs the vibe. Yet, as with all RELs, the styling conveys far more than simple comfort. The down-firing 12" driver, while unseen, will surely be felt. Continuing to the rear panel, one finds the period-correct detailing extends to the amplifier panel, where all controls are finished in lovely white gold. Everything that one encounters has the heft of quality switch gear, even the click made by the phase switch is near perfection. Quality abounds everywhere one looks or touches. Don't be surprised if your children fight over it later in life.

Driven to be Louder. And Quieter.

As anyone familiar with REL will tell you, we always begin with the driver. In this case, a bespoke 12" long stroke driver that uses lightweight, stiff, hot-pressed paper to form the main body of the cone. Laid atop that is a stiff center cap made of hand-thrown paper; to randomize the fibres, ensuring that the driver has excellent self-damping. This is one of REL's secrets. Understanding that it is the quietness, that attention to bring the driver to complete silence, that produces the most startling dynamics. Whilst Classic 99 will play shatteringly loud, it's from the very black background that the loudest dynamics emerge to produce the sense of shock sought by great composers and directors.

More than Ample Amplification

Classic 99 is big, bold, and full of character, similar to the Stentor II of our youth, but at one-third the price. Of course, the 99 has a great amp. In order to generate deeper bass and significantly higher output, we turned to a tried-and-true Class D amplifier that we've already used in thousands of previous units. This 450 watt amplifier is fed by an all analogue PerfectFilter™ front end that extends useful output well into the low 20 Hz range – superb for a design of this size and price. It produces a sound that's both rich and richly detailed at the same time. Classic 99 borrows the best from current technology to deliver a sound slightly warmer and more like what we all imagine vintage sound to be, with superior reliability and performance than was ever available back in the day.

Classic RELs: What's The Difference

How does the Classic 99 stack up against the hot little Classic 98?

While they look similar, the newer Classic 99 is some 50 percent larger (by volume) delivering 450 watts of power (300w for CL98) into a 12″ driver (10″ for CL98). Those are significant upgrades in the basic spec of the Classic 99. Yes, the Classic 99 is more powerful, plays louder and goes deeper. It should. We walk you through the untold, less obvious story that makes the Classic 99 truly special even while appreciating the magic that is the original Classic 98.

Our Summary

Product Strengths

  • Powerful, with great potential for room lock and shaking the listening room
  • Tuneful, clean, clear, and accurate bass
  • Deep bass extension
  • High build quality, with fine cabinetry
  • The on-board DSP with software offers flexibility with settings

Product Considerations

  • Expensive
  • Setup options can be overwhelming
  • Heavy, making it difficult to move around
  • The software may be complex to use
  • Built-in EQ may not be effective

Comparisons (according to reviewers)

  • Compared to the Velodyne DD-18, the Digital Drive Plus 18 (DD-18+) bettered it in raw power, transient articulation, pitch definition, and deep-bass extension
  • Compared to the JL Audio Fathom f113, the DD-18+ created room lock that a single Fathom f113 couldn't

Perlisten

Massive bass, minute distortion levels, just as we intended. Grills are optional.

MODEL D12s Subwoofer: Small footprint, big sound. Benefiting from many of the technologies of our flagship subs, these sealed subs generate amazing performance in the smallest footprint. Low Q, shallow rolloff response geared for sound quality and smoothly integrating into the listening room. Also, a great choice for using multiple subs to optimize in room response and smooth out seat-to-seat variation.

The smallest subwoofer in the series, yet packs enough punch to be certified THX Dominus using a pair of D12s subs. Powered by our 1.5kW amplifier, all functions and safeties are controlled by a 48-bit data bath DSP and 32-bit ARM M4 Cortex processor, able to react in microseconds, powerful enough to slam.

Ground up drivers developed by our team of engineers. Carbon fiber composite diaphragms, multiple aluminum shorting rings, massive magnets, multi-layer Nomex spiders and lightweight aluminum voice coil wire are the key ingredients – Proprietary nonlinear modeling techniques allow us to simulate all these components and then optimize for real world driver performance – free air and in box. Further refinement is done with the aid of Klippel laser measurements to dial things in.

All D-Series subs share our 2.4" LCD touchscreen display and ability to control advance settings using our App.

Perlisten Audio's speakers feature a unique Directivity Pattern Control array that combines a beryllium tweeter with thin-ply carbon diaphragm midrange drivers to control sound dispersion and enhance imaging precision, and they're the first brand to achieve THX Dominus certification. Their speakers use proprietary thin-ply carbon diaphragm material that's 30% lighter than standard carbon fiber, with their DPC array designed to minimize floor and ceiling reflections while maintaining precise horizontal soundstage.

Our Summary

Product Strengths

  • The D12s is Perlisten's smallest subwoofer, but still delivers impressive performance, especially considering its sealed design
  • Features a powerful 1.5kW amplifier, a 32-bit processor, and a TI DSP
  • Has an intuitive mobile app for controlling settings like gain, EQ, and parametric EQ
  • The D12s produces clear, fast, and tight bass, making it very musical and integrating well with various systems
  • Offers parametric equalizations, with each one giving you 10 parametric equalization bands
  • Requires a spare preamplifier output since it only has XLR and RCA inputs, unlike some active subs that use high-level outputs

Product Considerations

  • The D12s is quite heavy, weighing around 90 pounds
  • One reviewer noted a spike around 60Hz in their room
  • Might not be ideal for very large rooms or those who prefer very bass-heavy music like dub—unless paired with larger units

Comparisons (according to reviewers)

  • Vs SVS-2000 Pro, the D12s has significantly lower THD at 20Hz, even at higher SPLs
  • Vs Arendal 1723-1V, the D12s sounds clearer, faster, and tighter
  • Vs Velodyne DD12+, the D12s is comparable in dynamic bass performance, but has more modern technology
  • Vs REL offerings, the D12s performs similarly in terms of speed and clarity but has more power

Takeaway: The Perlisten D12s is a high-quality subwoofer that offers a combination of power, precision, and advanced features, resulting in a detailed and immersive listening experience for both music and movies. Its versatile design and user-friendly controls make it a great addition to any high-end audio system.

Their Music Integrity Engine corrects timing errors in the speaker crossover, and their Shadow Flare technology reduces diffraction for improved detail and clarity in sound reproduction.
Expand Details

Our Summary

Product Strengths

  • The KC62 is a compact subwoofer, described as tiny and about the size of a soccer ball or basketball, making it easy to accommodate in various rooms and spaces
  • Delivers incredible bass for the money and size
  • The KC62 provides powerful, deep, and accurate bass reproduction, especially in the lower frequencies
  • Features unique Uni-Core technology to fit two woofers into a small cabinet, reducing unwanted resonances

Product Considerations

  • Small subwoofers can't do what bigger subwoofers can do, although capable
  • App control does not provide direct access to remotely control the sub's own manual settings, therefore, some adjustments still need to be made on the back
  • In a big room, it'll definitely lose some steam

Comparisons (according to reviewers)

  • The KC62 extends quite a bit lower than the SVS Micro 3000 and is going to have really good extension, especially at lower volumes
  • The KF92 has a max SPL that's double the one offered by the KC62, making it a great option for larger listening rooms or home theaters
  • The KC62 has a faster response than the REL T/9x, which enhances the vibrancy of percussions in music or exciting moments in movies

Takeaway: The KC62 is a small but mighty subwoofer that delivers impressive bass for its size, making it an ideal choice for those with limited space who still want a great listening experience. Its stylish design and innovative technology make it a standout product that can enhance both music and movie enjoyment.

  • Some reviewers note that while improved, older REL designs could have a lack of control over the bass

Comparisons (according to reviewers)

Our take on the brand

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.

Buchardt
For many who follow us, this has been a project we have worked on for over 2 years now. We wanted a subwoofer that would be less intrusive in your typical home but, in typical Buchardt fashion, perform well beyond what users expect from its size. The SUB10 features a very powerful long-stroke 10" woofer that has been designed specifically for this exact enclosure and Hypex amplifier.

Buchardt Audio is a direct-to-consumer speaker brand that uses an "upside down" design with a back-mounted passive radiator, which helps create high-end sound at more affordable prices. Their speakers are engineered with advanced measurement technology and a proprietary waveguide design that enhances off-axis listening, while delivering deep bass from compact cabinets that rival larger floor-standing speakers.

How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we  discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.
