At first I was dubious about the idea of attaching a one inch diameter exciter to the back of a one inch thick 3 ft. x 2 ft panel of extruded polystyrene foam. I certainly didn't expect much. Man was I wrong! The sound emitted was so clear and accurate that I was floored. I ordered three more exciters from Parts Express and ended up with two panels, each with an exciter. They were powered by my trusty Sansui receiver. Although the panels weren't properly positioned - the best place for them is hanging free from a ceiling - they still sounded terrific. I placed them about 7 feet apart and toed them in slightly. I was amazed at the fact that they had some tangible bass response, which probably in the region of 50hz. I paired them up with an Orb Super 8 subwoofer. Small but mighty. I turned the bass volume switch up just a bit and set the crossover point at 80 hz. It matched perfectly with the panels. With a live jazz recording playing I determined that the sound was the very best I'd ever heard. The piano had weight, the drummer thumping the bass drum was very lifelike. The decay of a cymbal strike was longer and more perceptible than any conventional speaker I've heard. The sound of a piccolo is something that sounds almost ear-splitting with most speakers. It was clear as a bell with the panels. I would post a photo, but there isn't much to see save two green panels resting against some tower speakers. Listening to them is an incredible experience. Eventually I will have 4 panels in strategic positions so that the experience will be similar to that of a surround sound system.
