The improvement with an electronic crossover and separate amp over a passive crossover (even with biamping) is considerable. Get one as soon as you can.
x-cross overs HELP
I'm looking at a new sub and eventually a seperate amp. Till then I'll be sharing the fronts amp(BAT vk200) with this new sub. This is not a powered sub and I don't think I want to use the x-over from the sub company(their x-over is optional $50). Here's the kicker, I don't know anything about x-crossovers, let alone the best way to set them up. Any help would be greatly appreciated. Just cause I own audio equip doesn't mean I understand it.
