I really wanted this to work, but I think there is no way. This would have been for a guitar amp cab.
What I wanted to do was build a large array of small-diameter speakers in a tri-angled cabinet. I wanted to use speakers of 4" diameter or less. Hopefully very cheap speakers, as I was thinking that about 30 or 40 of 'em would be necessary to move enough air.
Try as I might, I could not find any speakers that fit all of the following criteria:
-- 4.5" diameter or less
-- High-efficiency (min SPL of 95dB @ 1W, hopefully much better than that)
-- Full-range - full enough to cover the guitar frequency range, anyway
-- Cheap - and I mean dirt cheap
I found some 3" full range drivers (OK, OK, they are computer speakers) that cost like $4.95 each but their efficiency is very low, like around 84dB, so that won't work. And Fostex makes some very small full range speakers in the 5" - 6.5" range but they cost a fortune and require a transmission line enclosure, which would be enormous.
Unless someone can point me to some small, cheap, efficient, full-range drivers that I haven't been able to find, I don't think this is going to work out.
Sure would look cool, though.
