After a long and hard road trying to get open baffles to work i gave up on crossovers and went the Vic at Transcription route. Have to say here and now Vic is a true gent and very very patient to a complete numpty like me. But after getting all the drivers and tweeter from him i went about designing the baffles.
i got a sheet of very good baltic birch ply, 18mm thick and glued these together and cut 2 rectangle slabs. Ithen bought realwood American wallnut veneer and popped my drawing and wood to a shop i have close who CNC machined the bevaled egdes and holes for the drivers then finished in a satin clear lacquer.
I fitted the drivers and tweets then wired up with cable talk 3. Bought a pro amp and a berhinger DEQ2469 for the eq of the 15" selenium neo bass drivers. I run the bastanis 12" and tweeters with my hyperion class A 18w valve mono blocks. Now from the off these sounded rather good but the bass was still playing some mid and treble. I messed about with the DEQ and got the bass drivers doing from 150Hz down the 12" does from that point upto i think its 16Khz ( not sure if this is right) and the tweets do all above that. the difference was really profound with a lot better bass and the mid although a little shouty was crystal claer.
Got a freind who know more than me ( not hard to do) and he set it up but intrduced some EQ into the bass to drive the 15" deeper and this in turn seems to have smoothed the mids. what im getting now is utterly butterly lovely with REAL deep bass no nasties at all detail to Die for and a big big sound top to bottom. I love these speakers so much so my Living Voice Avatar II's are now sulking in the spare bedroom. Only thing i dont like is the hum im getting from a nasty cheap pro amp that drive the bass. Im looking for a pwerful stereo amp to replace this so anything yoiu can recommend would be good. Something like a rotel with 180 to 200w or so and black would be good.
