I have an addiction making speakers, wanted to try some high efficiency drivers, so made these. I was using a MiniDSP 4x10 for these speakers and tri-amping them so you too would need such a setup. The drivers are: - JBL 2226H in custom larger ported cabinets. Pretty cool looking but not full on spray booth furniture grade. Very heavy though with 1.75" thick baffles. Well built and braced. Covered in black solid core arborite on the sides and finished baltic birch for the backs. Speakon connector. Bought these used. - JBL 2445J midrange compression driver and horn. These fit into the open baffle (they don't really radiate back) setup. Direct wired. They work properly and measure the same. I installed new aftermarket diaphragms a couple of months ago. Bought these used. - B&C DE250 Compression drivers with horns. The premier tweeter for projects like this. Widely regarded as having some of the best specs and sound at almost any price. These tweeters/Horns fit in the open baffle and then can be switched to the sealed midrange box. I bought these new. - B&C 8PE21 Midrange Cone Drivers. These go in the sealed cabinets with the DE250 tweeters. The cabinets were repurposed and are 1.75" thick. Very heavy, completely inert. Black solid color laminate. These drivers I bought new. The Minidsp will be unneeded but would be $700 extra. It is a modified version I bought off canuckaudiomart for a significant amount of money that was modified by the previous owner. Crazy thing to do, very difficult, but essentially upgraded the capacitors in the signal path and maybe some op amps. I truly don't remember. The mods only affected the Balanced Outputs. Completely changed the soundstage I thought when testing it against my original unmodded one. I don't really want or need to sell it, but will if the person is interested enough in the project. It would have my settings programmed which would be helpful.
