[Testpattern]

Forgive me. Poor wording on my part.

When I said I was sweeping up to 400hz I meant I had set up REW to sweep to 400hz. I did this to check the transition from sub to mains when running all three. However, when disconnecting the mains I still see acoustic response past the cutoff up to where the sweep terminates. I was expecting the rolloff of the A/V LFE filter to quickly eliminate signal after the 80hz crossover frequency. It does follow the filter's rolloff down to about 56db then things randomly fluctuate between 56db and 46db on out to the sweep termination at 400hz.

I can play with filters and various curves and see direct effects in the area below the cutoff where I'm working, but every graph I get has this acoustic information out beyond the cutoff for some reason.

Thanks for the patience on this.
