212/SX builds on the strengths of the 212/SE. Upgraded alloy drivers with carbon fibre blades are stronger, a new flat passive radiator extends even deeper and the PerfectFilter™ delivers crushing low bass with greater speed and air, taking 212/SX well beyond its illustrious predecessor.
Whilst 212/SX thunders and shakes foundations, it also resolves detail and restores midrange warmth to its correct balance. At 1,000 watts with (4) 12” (350mm) drivers, 212/SX drives rooms hard and in multiple modes which allows it to create richer bass everywhere in a room.
Refinements to both the legendary ultra-fast filters and newly developed drivers produces harder slam and brings to life quieter, gentler moments, improving system performance at both extremes. Plays brilliantly with both high end 2-channel and large power theatre applications.
Lightweight carbon fibre blades firmly attached to the rear of each active alloy cone serves to both strengthen the cone and quiet it. The twin 12” (350mm) 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.
REL’s uniquely tuned passive radiators use special suspensions, now with an additional 30mm of linear travel, to produce performance far beyond conventional subwoofers. The new SuperProgressive™ passive radiator produces extremely long travel allowing for very loud output while retaining the variable stiffness of its suspension.
The down firing passive produces deep, floor-crawling bass that makes a room shudder. Mounted above the amplifier panel on the rear is the second passive. This unit produces wrap around “atmospheric” bass that adds air and shimmer to the sound. Coupling with either the rear wall or the rear corner of a room allows for bass to develop exceedingly long wavefronts and adds an ease and effortless quality unique to single-box designs.
