Napkin math inc:Ugghhh see this is what I think was the issue they are 86db efficient and the 590 are 92db efficient I'm at 3 meters back from the surround speakers
So I had to run the channel trims on the AVM 60 up like 7 to 8 units higher for the 530 maybe a little more to level match them to 75db with the 590 mains
Top that off those rears were on the PVA 7 which with all channels driven is not putting out much juice yeeeaaahhh I'd say it's probably safe to say I clipped them and blew the tweeter oh well not my first goof up sure it won't be my last
According to Anthem, the PVA 7 has ~100W @ 8Ω per channel - all channels driven -.
If you calibrated to 75dB, add +25dB headroom for peaks = 100dB max SPL.
86dB -> 92dB (sensitivity match) = 4W (while you other speakers get 1W).
IIRC you lose some 3-4dB per doubling of distance in a room, lets make that a simple -6dB for 3m distance.
So you are back to 86dB (at already 4 watts, mind you) but you want 100dB, and amp power doubles per 3dB:
101dB would equal to 128W of power.
Mmh it's possible you overtaxed the amp but that would depend how it would re-route power from the other channels that need 6dB less output due to higher sensitivity.
I'm sure some other member could calculate that much more precisely.
