Introducing RELs LongBow™ the easy-to-use ultra high quality wireless system that frees your system from placement limitations imposed by conventional cables . LongBow permits very fast uncompressed bass to be sent wirelessly within the same room approximately 45 feet (somewhat dependent upon room clutter). Conventional wireless systems operate by hugely compressing the sound shipping the compressed digital bitstream through the air and then expanding it back to its \"original\" form.
