I have a Denon X4000 and an Outlaw LFM-1 Plus sub.
I ordered an SVS PB1000 to help with some nulls. I am going to soon sell the outlaw so I will have dual subs of the same brand.
The SVS doesn't have the same extension as the outlaw, only by a few dB, but I was curious if I could somehow set the low crossover point on the SVS to 20hz or something like that and get the outlaw handle everything below that.
