Hi Scott, Thanx for the encouraging words. I love the vintage drivers. The EV drivers I have are not too vintage, and their T/S parameters indicate 20 cubic foot boxes. Of course, If i power them separately and have an active crossover, all i need worry about is flatness in teh 30-60 HZ range, and not SPL. Maybe a small sealed box would work with an active crossover and a large enough amp. might try that in the near future. Sounds like a good idea! -akhilesh
