The thing about the Proac is the Scanspeak drivers. This 7" inch driver is the best I've ever heard. It was used in a package called the "Solist" from Madisound (WWW.MADISOUND.COM)and it just stole my heart ($1500/pr). It was demo'd at out audiophile society meeting and I just couldn't believe what was coming out of it. I just don't understand why Proac, et al, think the lumber they surround the drivers with must cost an extra $6000...
