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
Ok, so what measurements do you have for the underseats to your listening position if you have them? Thanks.
