 REL subwoofers are engineered to deliver deep, powerful bass in both stereo and multi-channel systems. Even full range loudspeakers can often not extend to the lowest bass frequencies, which reduces the impact and involvement for the listener in both music and movie playback.

 One of REL's most innovative releases yet, the LongBow allows you to integrate a high quality subwoofer to your existing home theatre or hifi system completely wirelessly without compromising on quality.  LongBow is designed to transmit signals at a phenomenally quick speed without compressing the file, so a truly accurate bass can be sent wirelessly within the same room up to (approximately) 45 feet away.  

Traditionally, wireless subwoofers work by having a largely compressed file transmitted to the subwoofer, where the compressed signal is then expanded and put back to it's 'original' form. The issue with this is that it results in a noticeable level of latency and quality loss. LongBow is unique in that it uses an entirely different process, upgrading the signal from 16bit to 24bit and then sending uncompressed 48kHz signals to the LongBow-compatible subwoofer. This is achieved via the LongBow audiophile-grade analogue to digital encoder, ultimately resulting in a much faster (around 80% faster in face) performance than can be achieved via traditional Bluetooth or WiFi wireless sub systems. 

LongBow has been developed to work with both high level and .1 channel simultaneous delivery, so a rich and room filling theatre experience is achieved at all times. Shifting back and forth between music and film sound requires NO switching of inputs, altering subwoofer settings or the like.
