A little late to the party, but I use the dbx driverack PA+ in both my home and office setup. I dont always agree with the auto-eq wizard, it thats why I use the Omnimic from Dayton to optimize the frequency response. 8 parametric bands per channel after the active crossover, PLUS another 8 bands to shape the signal even further before the active crossover and it makes for an awesome system with great capability.
