Ok, got about an hour in with just one
Josh is right, this has a very "neutral" sound, very crisp. It's also very efficient, and has no issue maxing the SPL meter at any frequency 30hz and up with just one.
It's also very efficient. With two Ghorns, I have the receiver sub out at -8db. With all the gains and volume knobs in the same position, I have one othorn at -10db, so with two I'll need to turn the gains down on the amp.
I'm very impressed, this thing slams. I was contemplating replacing a single clone with two CV-5000 amps, one per Othorn, but the clone is far more than adequate in 4ohm stereo to push these.
I can understand Josh doubling the bracing. The Ghorns and these generate MASSIVE cabinet pressures. It's unreal.
I'm done building subs for now
