REL Acoustics 212/Sx Subwoofer

Our Take 

The REL 212/SX is a stellar performer redefined, now delivering more power with effortless clarity—elevating volume, enhancing precision, and preserving the finest nuances of air and space like never before. Powered by a cutting-edge 1,000-watt NextGen 5 Class D amplifier, this subwoofer features an impressive array of drivers: two 12" Continuous CastAlloy™ Active Drivers, a 12" rear-firing passive driver, and a 12" down-firing passive driver. Together, these drivers produce deep, room-filling bass with exceptional control and balance.

At REL, a deep understanding of quality underpins every aspect of the 212/SX’s design. While it thunders and shakes foundations with authority, it also excels at resolving intricate detail and restoring midrange warmth to its proper balance. With its powerful 1,000-watt amplifier driving four 12” (350mm) drivers, the 212/SX is capable of driving rooms hard in multiple modes, delivering richer, more immersive bass throughout any space.

Product Details 

Refinements to REL’s legendary ultra-fast filters, combined with newly developed drivers, enable harder slam and bring quieter, more delicate passages to life with remarkable definition. This subwoofer performs brilliantly with both high-end 2-channel stereo systems and large-scale home theater setups, elevating system performance across the frequency spectrum to new heights. The 212/SX delivers powerful, precise bass performance that transforms the listening experience, whether for music or movies.

Double Down
Lightweight carbon fiber blades firmly attached to the rear of each active alloy cone serves to both strengthen the cone and quiet it. The twin 12” (300mm) active drivers now offer an additional 12mm of stroke and also benefit from updated suspension geometry and greater power handling. And a brand-new double-spider, high powered passive unit on the bottom delivers floor rippling low bass. The result is a major step forward in the 212 design, an already brilliant performer now playing louder with greater ease whilst better preserving the tiniest details of air and space with even greater precision.
