With an aesthetic and design based on those of the celebrated 212/SE, the REL 212/SX is a true reference achievement designed not only to provoke literally visceral sensations when listening to music, but also to maximize the resolution of details and restore the warmth of the media. It combines a total of 4 newly developed 305 mm speakers (2 active and 2 passive) with 1,000 watt continuous NextGen 5 amplification electronics, developed by the British firm, and sophisticated management circuitry. In the case of active speakers, ultra-light carbon sheets hermetically fixed in the rear area of each cone "Continuous CastAlloy" exclusive to REL make it possible to harden and at the same time soften the behavior of the latter, while updating the geometry of the cone. Peripheral suspension and superior power handling capacity allow it to increase its already extraordinary displacement capacity by 12 mm.

A special mention deserves the impressive "Super Progressive" lower emission passive bass radiator, which by combining a flat diaphragm with REL's exclusive "Carbon/Carbon" structure, a steel chassis and a newly developed special internal double suspension It allows you to further increase the maximum sound pressure level and bass extension thanks to an additional 30 mm of travel, while preserving the most subtle spatial details with extreme precision.
