REL Acoustics Classic 99 Subwoofer - Walnut

What You Need to Know

A Modern Classic with Vintage Soul

The REL Classic 99 is a potent symphony of design, power, and grace—a design that captures both the eye and the ear. Channeling the timeless charm of mid-century modern stereo gear, it wraps a thoroughly modern REL in hand-fitted natural walnut veneer, with solid cabinet walls up to 32mm thick, softly radiused billet-aluminum feet, and rear-panel controls finished in white gold. Even the click of the phase switch feels like quality. Don't be surprised if your children fight over it later in life.

Warm, Deep, and Effortlessly Musical

Beneath the furniture-grade cabinet, a bespoke 12-inch long-stroke driver fires downward through an acoustic-suspension (sealed) design. Its cone is hot-pressed paper topped with a hand-thrown paper center cap—randomized fibers give the driver exceptional self-damping, and it's from that silent, black background that the most startling dynamics emerge. REL compares its big, bold character to the legendary Stentor II of decades past, at one-third the price.

Modern Power Behind the Period Details

A proven 450-watt RMS Class D amplifier, fed by an all-analog PerfectFilter front end, extends useful output well into the low-20Hz range (-6dB at 24Hz)—superb for a design of this size and price. Connectivity is full REL: the signature High-Level Neutrik Speakon input (33-foot cable included) for seamless blending with your main speakers, plus Low-Level and LFE RCA inputs for preamps and theater processors. Optional HT-Air MKII or AirShip II wireless is available separately.

Frequently Asked Questions

Is it good for both music and home theater?

Yes—that's the point of the Classic line. The sealed cabinet and paper-cone driver favor the warm, textured, effortlessly musical bass two-channel listeners love, while 450 watts and low-20Hz extension deliver genuine theater impact when the movie calls for it.

What does the High-Level input do?

It's REL's signature connection: the sub takes its signal directly from your amplifier's speaker terminals (33-foot Speakon cable included), so it hears exactly what your main speakers hear—including your amp's sonic character. Most listeners find it gives the most natural blend. Low-Level and LFE RCA inputs are also on board.

How does it differ from the Classic 98?

The Classic 99 is the larger, more powerful model in the Classic line, stepping up to a 12" driver and 450 watts for bigger rooms and deeper extension, in the same mid-century walnut styling. Call us and we'll help you choose.

Can I make it wireless?

Yes, with REL's optional HT-Air MKII (Low-Level/LFE only) or AirShip II. Note that a power outlet is still required at the subwoofer's location.
