Altec 604e/Alpha 15 OB?
I'm way over my head here but have an idea prompted by the recent OB thread.
I have a pair of 15" Altec 604e coax drivers in need of an enclosure. They are suited for a vented 9 ft box - but I don't want to do that and my wife really doesn't want that.
I was thinking about an OB with the 604e on top with two Eminence Alpha 15s to augment the bass. The 604e is not ideal in a narrow baffle (20"-22") OB - it's QTS is .21. So, from what I've read I would get an early rolloff especially on a narrow baffle - hence the two Alpha 15s. I understand that the Alpha (qts >1.0) is well suited for an OB.
This concept is kind of a cross between the Jamo 907, http://www.stereophile.com/floorloud..._loudspeaker/# and the Emerald Physics 2.3.
I'm thinking that the Altec xover handles the coax slope and I use an active xover between the coax and the two Alphas.
Any help would be much appreciated.
