Nothing Continues to Say Lifestyle like Mid-Century Modern RELs

Classic 99

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.


Less Wiring?

The future meets the past gloriously in REL’s wireless offerings. For the ultimate, select our Airship II which encourages the use of REL’s High-Level Connection PLUS .1/LFE should your listening tastes run toward movies. And these days who doesn’t stream quality video content? This is our ultimate wireless design at 5.8 GHz and uses discrete components in the front end to transform your system’s sound flawlessly into totally uncompressed wireless capable of eliminating the sprawl of cables across one’s living space.

On a tighter budget? We slip the exact same 5.8 gig master chip into an affordable system that allows for Low Level or .1/LFE to deliver across the same 35’ with the same bulletproof signal delivery that we’ve become famous for over the past 15 years. HT-Air MKII Wireless is one of life’s great bargains.


The REL Classic 99 delivers rich, full-bodied bass with exceptional musicality, making it ideal for traditional 2-channel systems. While it’s designed to produce powerful, deep, and tactile bass for home theater, it also upholds REL’s uncompromising standards for musical performance. To achieve these goals, it features a down-firing 12" driver and a 300-watt Class D amplifier, all housed in a beautifully finished walnut cabinet. The result is a seamless blend of modern performance and timeless design—perfect for those who value both sonic and aesthetic harmony.


The Classic 99 is purpose-built for music-first systems, delivering natural warmth, speed, and tonal balance that elevate any high-fidelity stereo setup. While it can add depth in smaller-scale home theater environments, its true strength lies in musical refinement—not cinematic impact.


Yes, the Classic 99 can be integrated with other REL models. For optimal results, it’s best paired with subwoofers that share a similar musical voicing—such as select models from the Serie T/x. With proper calibration, it can also perform well as part of larger multi-subwoofer systems.


Yes, the Classic 99 supports REL’s AirShip II wireless system, delivering high-quality, low-latency transmission without the need for cables. This allows for more flexible placement and optimal performance, all while maintaining a clean, clutter-free setup.


The Classic 99 is well-suited for medium to large rooms, typically between 150 and 400 square feet (14–37 m²). Its 12" driver and generously sized cabinet allow it to pressurize the space with ease, delivering spacious, natural bass that complements both vintage and modern hi-fi systems.


The Classic 99 is not designed for vertical line array stacking. It’s optimized for floor placement in traditional 2-channel systems, where it delivers rich, musical bass. For enhanced performance, Classic 99s can be used in stereo pairs to improve imaging and bass balance throughout the room. If you’re seeking line array capability or theater-grade output, consider REL’s Serie S or Reference Series models, which are purpose-built for those applications.
