I just learned from my crossover builder, Trey vr3mods.net, he's amazing, that I should not run these speakers without a dreadnought as a common ground. I just bought a preamp and mono blocks, they are on their way, and I'm trying to operate in a tight budget (these are gifts to my father). Is there ever a way to run mono blocks without the dreadnought and where do I find one that gets the job done for a reasonable price? Thank you all! I just want this to work well for my dad.

    Ummm...Trey has been a member here since he was 12 or 13. We all know Sid the Kid.

    Some mono blocks can have the negative outputs strapped, but you need to confirm that is possible by asking the manufacturer. If it is possible be aware that doing so defeats the purpose of mono blocks and raises the noise floor.

    Best to buy the isolation transformer. Search here for Dreadnought.

    BTW, on a tight budget and crossovers from Trey are polar opposites. Best not mention you are on a tight budget again.
