I was running the 20-30PCi through Avia and noticed that around 70Hz the SPL dropped off, then came back at 60Hz.

Is there a way to fix that? Is that crossover?

20Hz? perfect, and AWESOME!

I place the monolith in 4 different spots and this seems to be the best . . .at the moment.

BTW - new stands are next and after those you will start hearing questions about new surrounds.

It could be the crossover. What do you have it set to? It could also be room issues. I would try setting it to 80hz.

Try adjusting the phase control and re-running the Avia sweep. Try 180, and 90 first. Then try to hone in on any possible sweet spot in 15 degree increments. Some drop-outs can be corrected with phase; others can't.

The only way to really tell what is happening in the room is to plot the FR with some test tones, the SPL meter, and a spread sheet with correction factors.
