Still loving my Thiels, but I had a calibrator in today and he discovered something strange.
Currently I am using three 1.6's across the front, two PowerPlane 1.2's for the surrounds, and a SW1 sub. And the PX05 -- though it was configured for when I had 1.6s all around, so now I bass manage surround music in my processor, and just play two channel in full range.
So the PowerPlanes are new and it was time for a professional once over. (I needed floor space, so the 1.6s I had been using for surrounds got replaced.)
The integrator found that the PowerPlanes in room response dropped off pretty quickly below 120hz, even when the pre-pro crossover was set to 80 or 100hz.
So he tried to raise the crossover for my surround channels up to 120hz.
But the SW1 had a pretty fast drop off above 100hz in terms of in room response. (This is via the LFE input, coax, from the pre-pro.)
I realize that in room response can vary greatly from the specs.
But since the PowerPlanes are rated to get down to 70hz and the SS2 (essentially my SW1) is rated to go up past 200hz, I was surprised by this behavior in room.
Are there any high or low pass filters in the sub or the powerplanes that might be configured in a nonstandard way. Or perhaps there is another nuance I am not considering.
My suspicion, but I didn't have time to test it, is that even though there's no rational reason for the PX05 to do this, maybe it is....
(I've also got a msg in to Gary, who has been very helpful in the past in areas like this. But I'd love to get it sorted for this three day weekend.
