Hi Wayne,
Did you compare -- just for fun -- your P. Wayne Sub to the ServoDrive Basstech7 "THE WORLD'S MOST POWERFUL SUBWOOFER".
(http://www.servodrive.com/basstech7.html)
I know there are different techs involved. Just for the sake of it. After all is (a work of) Art.
Some people need power -- "A single ServoDrive BassTech 7 can exceed 114dB at 100 feet away" -- to compare jets in airports.(http://www.prosoundweb.com/install/spotlight/jets.shtml)
Servo drive speck: Sound level at ten meters = 124.5dB (continuos 400W)
From Pi Speakers SPL vs Freq graphic a pi SUB (taken at 10 meters) = 118dB (1600W).
I think you name it in October 12 2005 as a pair of Servodrive BT-7 hornsubs at 136dB. Yours... 137dB at 1 meter.
From servodrive website: 2 units - 107.5dB (1W, 1m), max. rated of 2 units - 136dB
From Pi webforum 12π basshorn subwoofer: a pair should run 143dB (+/-) maximum output at one meter.
After all is there a difference of about (+/-) 7 dBsSPL at full power (rated) @1m?
I know you runned tests at 2400W "π basshorn subwoofer at 2400 watts".
What is (about) the dBSPL@1w1m of the Pi SUB if you have a pretty close idea?
