It's a sound reinforcement processor, similar to , but much better than the Aural Exciter. This single space unit plugs in between the source and the amp and adds an octave of bass BELOW the lowest note, a thunderous lower mid punch, and expander that opens up, separates and imporoves the highs, AND a dedicated subwoofer output.

All I can say is WOW. I tried one today with the Barbettas and it was a night and day difference. I didn't like it too much with the 12" speakers in the past (Mackie, EV) but with a 15" - it really shines.

Check it out today ..... IF you use 15's, that is. It is simply awesome. Brian - YOU need this for your DJ rig. It is wonderful. Simply wonderful.
