I have a very large room, and at this point I still use small on everything and 80hz crossover on my Denon. I played around with setting my 80's to large and using LFE+Mains to see if that would help with the nulls/peaks. I did not see much of a difference if any.

Some day I hope to add additional subs on the other 3 walls. \:\)

Thanks John. That explained a lot. My Sony receiver, that will soon be replaced by a Onkyo 875 as soon as it arrives, has only 60, 90, 120, and 150 crossover settings. Right now I have all set to 90, but previously I had it set to 60 for mains and 90 for the rest. With music, all 2 channel, I prefered the 60, but I listen to movies the most and so I didn't want to lose the LFE and I set it to 90 for everything. I didn't find any difference in quality for movies, mostly because I don't really listen for that during movies, and the music is not as repeatable like with a nice bass guitar while listening to music. I'll try 60 again. With the Onkyo, I'm thinking 50 will be a good crossover point for my m60s and 100 for the vp100 and qs8.

If you had the capability ie a stereo direct mode for music, how about shutting off the sub and just listening to the M80s large as a stereo pair. While its not as important for HT listening a single sub does introduce phase differences when listening to stereo. Nothing beats floorstanders for music IMO and the M80s are great floorstanders.

I managed to get rid of my phase issues by increasing the sub distance in my Denon's menu. My sub is 11 feet away but, through trial and error, I upped it to 19.

I do indeed have stereo direct but I find that even though the 80s have great low frequency extension, without the sub, they sound thin. Thin is perhaps too harsh a word but you know what I mean. I can't live without a sub now...even for just music.

I discovered that the M80s have significantly more low frequency prowess (in the subjective sense of gut-thumping bass) when the A1400-8 powers them at higher volumes vs my Yamaha DSP-A1 (110W/ch). For this reason, I prefer the EP-500 off for stereo mode while listening to music.

Showing off is over at the Community section \:\) . Merely pointing out that M80s don't have "thin" bass to my ears in my system.

Thin bass on those full range M80s is a sure sign that Mojo is underpowering them. There is no getting around having power on tap for accurate and full bass response.

Good post John. The A-1400-8 let's you realize the full dynamics and deep bass of those M80s. Adding a sub to floorstanders just muddies the music unnecessarily when the real problem is lack of power for bass control.
