I have some of their info but it was on a computer that crashed and might be difficult to dig up. They are good speakers, and they have some of the large scale quality that vintage Bozaks do, but with much less panel resonance (the front baffle is something like two inches thick and the rear of the enclosure is actually a sonotube cut in half and built (with sound absorbing foam) into the external enclosure. The drivers and crossover components are excellent quality. Vifa and Seas and Peerless? I think.
I found the pair I have to be a rather difficult load for for some amplifiers -- a Toshiba integrated just couldn't handle them. Their looks are not met with universal approval -- to my suprise the WAF was low in this house, so out they went to the shed. (Not sure the ESS Transtatics that replaced them were any lovelier, but they are so freaking heavy they are staying in place until someone takes them away.)
I think that the asking price may be significantly higher than is realistic. Whatever their audio qualities, they suffer from the disdain of 'real Bozak' lovers and the blank unknowingness of any other potential buyers. For that kind of money you can get some nice vintage Bozaks, and be able to get your money more or less back again if you decide to sell. Not likely with this pair.
PM me if you want me to look around for more info.
