Founded in 1990 by Richard E. Lord, REL is the only sub bass system on the market that restores missing bass detail from main speakers, reflecting the full expression and power of what instruments sound like in real life. REL is a step above its competition in its ability to play both low-frequency effects (LFE) and amplifier level to restore the missing bass detail of main speakers. This unique ability to play both signals at the same time transforms movie soundtracks into more spacious, detailed, and dynamic experiences, making REL speakers the ideal sub bass system for both hi-fidelity stereo system and surround sound system. REL's proprietary crossover designs mean you’ll never have to experience sound smearing or audio lag – instead, you’ll get superior tonal density and perfect sound integration. REL makes top-of-the-line speakers for a top- of-the-line listening experience.
