Hey Mitch, I went to UVM back when most Vermonters were packing.
If you are blowing subwoofer amps I will assume you like rocking in which case a full crossover is mandatory if you do not want to overload your Salons. I would never go without a crossover. I also use passive subs with digital bass management and Two QSC amps driving 4 12 inch subs. Each one gets 2000 watts. Digital bass management is a huge step forward. The dbx driverack is a relatively inexpensive way of doing it. But the Anthem STR preamp comes next followed by the Trinnov Amethyst which IMHO is the very best unit available today. I use a Tact 2.2x. Unfortunately Tact went under. It is very similar to the Trinnov. If you ever do room control you will need more power for your subs. The correction process requires power. At any rate forget the passive route. Bad idea. It is the cheap lazy solution.
