A pair of speakers built by a local speaker builder (Joe Berky) in Baltimore. They consist of separate monitor and subwoofer cabs. Monitors have an MTM design with a ScanSpeak Revelator tweeter between 2 Audax 5.25 inch carbon fiber midranges. Bass cabs have a single Scanspeak 8 inch driver. Hovland caps and alphacore inductors in the crossovers, about 89-90 db.
I bought a pair of ProAc 2.5's over Audiogon last year. UPS gorillas appeared to have dropped them from about 10 feet. Took them to Joe Berky at SoundProjects to see about repairing them, but ended up returning them to the seller. In the process I got to know joe and was impressed with his speakers.
