They say music soothes the soul, but poor control on your system can kill the harmonics of a beautiful song or road-trip. If you want to extend great-sounding music from your source to your amps, then get yourself a Soundstream Digital Bass Reconstruction Processor. The BX digitally maximizes the ultra-low bass on all types of recorded material. The processor detects bass harmonics, then digitally recreates the original essentials for the incredible punch and impact of live music. Basically, you get more bass!

The crossover adjustment is conveniently located on the remote gain control.
