I guess I should have specified that, sorry. I had the speakers hooked up (without the sub) in "large" mode. I'm still pretty surprised that an HK AVR520 can't drive the M80's in large mode with no other speakers connected. However, with the EP350 hooked up and the M80Ti's in "small" mode, everything seems to be OK.
Since "small" mode cuts the frequencies below 90hz off, is that where I should set the EP350 crossover?
And you're right, the EP350 is quite a capable sub.

First, the x-over doesn't cut-off, it rolls-off, so your speakers will still be getting a signal below 90hz, just not as much. Second, if you're using the receiver's x-over, you don't want to use the sub's x-over, so either turn it off if possible, or set it as high as possible to get it out of the way. You don't want both the sub and receiver x-overs active at 90hz.

Doug, I agree with Jeff. To get the EP350 crossover as far out of the way as possible, the best procedure in general is to turn it to the 150hz max and leave it there.

Doug, I should also add that I share your surprise at the problem. Marc reported here that he's sold many M80/520 combos with no problem, so he's certainly knowledgeable on the point. It may still be that something in the protection circuitry of your 520 sample is out of whack(to use a technical term)but maybe it's best to leave well enough alone.

It would be interesting to find out if Marc has actually tried running them set to large or knows if any of the customers run them set on large, or have they by default just gone and set them to small without even trying it as Doug has?
