Your reaction, Zd, is somewhat understandable, since almost all active systems ARE in the pro world. They need efficiency and volume...maximum SPL per watt. They use Crown and Crest amplifiers, which sound like hell. Pro audio anything means reliability, it HAS to just WORK above all else, sound quality be damned. Lots of protection circuits. I started 3 threads by accident, so if you look at one of the other ones, the guy with Maggies says it all...he's running 2 Citation amps actively crossed over, and is realizing far more slam, dynamics, power, clarity...everything you'd want, and it's almost all due to the power drinking, time shifting, dynamics robbing passive crossovers. If you ever get to hear two systems side by side, one active and one passive, the difference is stunning. You have no idea how much is lost in those circuits between amp and driver.
