Ahem...the audio-pro B2-50 subwoofer uses (2) 5-1/4" drivers and I believe it is fairly flat down to 20Hz. A friend of mine designed a subwoofer based on the audio-pro idea. He used 2-6" phillips drivers in acoustically isolated, ported, cabinets. One driver faces inward and the other faces outward. They are connected electrically by a motional feedback circuit. The woofer has it's own mono amplifier. My friend measured the frequency responce as down 3db at 20Hz. It sounds VERY GOOD! Go listen to any of the audio- pro subwoofers. You might be surprised at the bass you can get from a moderately sized driver. -- __________________________________________________________________________ Tom Levin {ttidca|sdcrdcf|logico|scgvaxd|bellcore}!psivax!tommie You've seen those car stickers that say "Baby on Board"??? _________ I want one that says: / \ / Psychotic \ / On \ \ Board / \___________/
