I have the opportunity to acquire a pair of 8256s. Now, this is obviously only part of the story - the 3156s are rated as far as 2kHz.
I also have a pair of JBL 2426Js, and a pair of the complementary Bi-Radial horns - the 2370As. This looks, in frequency response terms, to be a good match.
There is an obvious impedance mismatch, but as I was planning to use tubes for the 2426Js, and a class-D amp for the bass, would this be less of an issue? Or is this a fundamentally bad idea?
Ultimately I would probably look to use the 15" drivers in a different way; one driver in a cabinet underneath the horn, and the other in a second cabinet above. A sort of d'Appolito pair of smaller 8182s or 8184s, sandwiching the horn. Something like this:

Perhaps a little smaller than these... And I'm not going to be trying for a curved baffle! These were made by a friend in Japan.
Thoughts? Comments? Suggestions for strong medication?
Thanks,
Graham
