Seamless Sound

NextGen2 250W Digital Amplifier

Beyond the drivers, the performance of a REL is determined by the input filters and amplifiers. REL S/2 uses a simple filter-type that is very fast—about 8 milliseconds in group delay to get through to our driver. This speed and carefully sorted filters allows for seamless blending of RELs with the main speakers.
S/2’s power amplifier is a powerful NextGen2 250W digital amplifier. This design has proven exceptionally reliable and very fast with deep, extended lows—it provides a perfect mate to its driver.

Freedom

LongBow™ Wireless Connectivity

LongBow permits very fast, uncompressed bass to be sent wirelessly within the same room approximately 45 feet (somewhat dependent upon room clutter). We have selected an un compressed format as it results in natural, quick delivery compared with conventional wi-fi or Bluetooth systems. Because it is a REL, we developed LongBow with both high level (or low level with crossover intact) AND .1 channel delivery so that REL Theatre Reference performance can be maintained even when using our wireless delivery system.
