I was in fact thinking exactly that; what if the extended bass I hear in other spots is in fact low frequency response error?

I triple checked; all connections are tight and secure, polarity is correct and all the drivers are working.

I don't have a subwoofer (well... I do, but it's connected to a HT system in a different room). One of the reasons for picking up the M80s was the hope that for music, I won't need a sub.

When you say you tried repositioning, how much have you moved the speakers around?

Good point, as I am not sure it was enough to make a difference.
1. From the wall: from almost touching the wall to about 2 feet. Currently they sit at about 1 ft, which sounded the best IMO.
2. Angle: from no angle to 30 degrees. Currently they are at about 5... very little toe-in. Again, the best sound, at least in regards to sound stage and imaging, which are "out of this world" to my ears.
3. Distance between the speakers: from 6 to 12 feet, currently at about 9.

I wonder if you can do something similar with one of your M80s?

I think I may have read it, but I did not try that yet. I'll leave it for last... if everything else fails. I'm thinking that my back will thank me grin

In some people's opinion, "somewhat obsessive"= audiophile laugh
Joking aside, I do have an SPL Meter, but no software yet. I will definitely would like to try the "by the numbers" approach.

The room is mine to "play", so that's in books as well; a friend of mine suggested to switch the speakers onto the larger side of the room. If nothing else seems to work, I would give that a try as well.

Thank you very much Gents for all your valuable input; my goal is to try and get the best possible sound out of my system. And of course, something to do in my spare time smile.

PS Does anyone think at this point, that it may be worth trying the automatic calibration that came with my Pre/Pro?

As long as you write down your current settings so you can revert to them, I don't see an issue with doing that.

I found it to be a straightforward, effective, and quick solution and I would recommend it to anyone with similar problems.

Does the UMC-1 have bass/treble settings? If so turn the bass up a notch or 2 to see if that helps with the lower volume play back. I like Audyssey just for this reason, it boosts the bass and treble for lower volume playback and it works very well.

Yes it does; it has an Equaliser AND separate, general Bass and Treble, but I didn't use them. I'll give it a try and report back; I tried to get the best possible sound without tone controls (although I don't think there is anything wrong with using it). But it sounds like a good, quick idea.
