We're weekend warriors to be sure. We play college theaters seating 400 mostly. Largest was 1500. We have 8-18s, 4 mid horns, 4 high horns. We are a classic rock tribute and use a 40ch Allen and Heath GL2800, tri-amped passive speakers and old fashioned effects, eq etc. I have a three way crossover, but also have a DBX Driverack2. I should be able to use this gear as a cross over as well as using it to manage my speakers right? Thank you for your input.
