I have some 2 X 12" subs, and one is about 6 dB too low (just a guess, using my ears. Each sub has a dual-channel Hypex plate amp.
I've tested all 4 amp channels and they seem reasonably close. The drivers also seem OK, so I'm wondering if perhaps one of them is out of phase?
Sure, I can just reverse one and listen if things improve, but is there actually a way run a signal through an amp, and see if the output is in phase?
- I'm guessing, yes, but I'd need a scope, which I don't have. - but I'm hoping for a software solution.
SO?
thx.

Face two of the subs together, an inch or two apart. Feed them both the same signal.
If the acoustic output drops significantly compared to when they are separated,
they're out of phase with each other.
