The only thing I can think of is that I'm using a DD1 to set the gains on the channel that those woofers are connected to and using a dd1 and a 1000 test tone to set them, when I should be using a tone that they will be playing. I'll be bandpassing them at 80-200hz.
Yeah that could be it, since the APBMWs response is up to 500hz
