From the manufacturer:

The modern era of REL began in 2005 when John Hunter and Donald Brody acquired REL. Almost immediately, they identified several key paths to take the strengths of the core REL philosophy and build upon them. First, the designs had to be updated and made to look as wonderful as they sounded. Second, for all their robust qualities, there was room for improvement in the area of electronics and driver technology. Accordingly, they set about on a comprehensive plan to upgrade and improve every aspect of the products; focusing on reliability, clean styling and robust mechanical construction–a path that continues to this day.

Today, REL is one of the fastest growing product ranges in the entire high end with strong international partnerships all over the world and acclaim coming from virtually every high end audio and home theater magazine. At its cornerstone, fundamental reliability remains its core strength, blended with a unique approach to design that results in what many consider the most musical and powerful sounding subwoofers available.

“The subwoofer’s task to deliver musical fundamentals below the reach of ordinary loudspeakers. It’s an approach that can work well with compacts, but often works even better with large speakers…” Alvin Gold Gramophone
