Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Paradigm designs and manufactures their own drivers, including the rare and expensive Beryllium drivers used in their higher-end Persona and Founder series, allowing for precise control over performance characteristics.
- They utilize Perforated Phase-Aligning (PPA) lenses over tweeters and midrange drivers, a visually distinctive technology they claim smooths and widens dispersion while protecting the drivers.
- Paradigm is known for integrating Anthem Room Correction (ARC) technology from their sister company, Anthem Electronics, to optimize bass performance and room integration of their subwoofers.
- They focus on delivering high dynamic range, enabling their speakers to play loudly and cleanly without compression or distortion, even at mass-market price points.

Product Strengths
- Impeccable and top-notch build quality and design
- Clean, tight, and powerful bass from a surprisingly small package
- Performs very well for both music and home theater
- Anthem Room Correction (ARC) is included for room calibration
- Sleek design fits into modern decor
Product Considerations
- The XR13 is not designed for someone that prioritizes performance and price to performance above all else
- Physics still apply and it will not outperform a larger driver subwoofer in SPL alone
- The 3m USB cable supplied for ARC may be too short
- App control may lead to end-user settings calamity
Comparisons (according to reviewers)
- Vs Perlisten R210, the Paradigm is smaller and just as snappy and articulate
Takeaway: The Paradigm XR is a beautiful and well-built subwoofer that delivers excellent sound quality in a compact size. It is a great option for those who want a subwoofer that looks as good as it sounds and still delivers powerful bass for both music and movies.

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 take on the brand
What competes at this price?
Our Summary
Product Strengths
- Uses two slim 'racetrack' drivers in a bipolar arrangement for vibration cancellation
- Housed in a 5mm thick extruded aluminum enclosure, contributing to both aesthetics and heat sinking
- Can be placed flat, mounted vertically, or attached to a wall, offering versatile placement options
- Delivers taut and tuneful lows, even reaching into the mid-20Hz region, especially when used with the Perfect Bass Kit (PBK)
- Maintains depth and power while providing well-spaced instrument separation
- Requires skinny speaker cable insulation without plugs for stand threading (MilleniaOne, applies when using stands)
Product Considerations
- The price tag may be prohibitive for some customers
- The MilleniaSub may be the relative weak link compared to the MilleniaOne satellites, as other subwoofers offer more punch
- A better subwoofer can be had (Seismic 110), without sacrificing much in the way of size
- Needs the optional Perfect Bass Kit (PBK) for optimal performance and EQ
Comparisons (according to reviewers)
- Compared to the B&W 800 series, the Paradigm system was limited in sheer scale
- Compared to a Velodyne 1,200W sub, the MilleniaSub is much easier to hide
- Compared to the Paradigm Seismic 110, the Seismic 110 possesses near nuclear punch
Takeaway: The MilleniaSub is a stylish and versatile subwoofer that delivers impressive bass from a compact design, especially when paired with its matching satellite speakers and the PBK. Its unobtrusive nature and ability to be placed in various orientations make it a good choice for those seeking performance without sacrificing aesthetics.

- Attention to detail in the design, including the fit and finish, and quality components
- Speed and transient response are praised, allowing it to start and stop quickly
- Multiple connection options, including high-level, low-level, and LFE inputs, increasing its versatility
Product Considerations
- May not provide the same level of 'body rock' and tactile feel as larger subwoofers
- May not be ideal for very large rooms where more output is needed
- The finish, while high quality, is only available in a limited number of colors

- The T/9x provides a more consistent experience overall, while the KEF KC62 is more versatile
- Performance rivals REL S3.
Takeaway: The REL T/9x is a well-designed subwoofer that can enhance the sound quality of a music system, especially in small to medium-sized rooms. It brings detail, clarity, and extension to the bass, making it a worthwhile addition for those who appreciate high-fidelity audio.
Video review
Our take on the brand
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
- The KC62's standby mode may not always engage, requiring manual volume adjustment to wake it
- 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.
