I have M60's, QSv8's and VP 160 speakers mated to a Emotiva MMC1 and IPS1 amp and processor. The Emotiva has "Side axis" capabilities, between the fronts and rear surrounds. I am wondering if a pair of Mirage in ceiling speakers between the 60's and the 8's would really "open up " the sound. I have a regular living room, 13x18. Any suggestions?

So are your Qs8's mounted to the sides of the listening area (as they should be in 5.1) or when you say "rear" are you referring to the sides and back surrounds in a 7.1 setup? If you have side surrounds, not really sure what "side axis" is as Emo calls it.

The Qs8's are on the sides, left and right,facing the center of the room, about 8.5 feet up. Due to the room they are about 2 feet away from the rear wall. That leaves about 15 feet between the M60's and the 8's. The "side Axis" speakers can be used to "fill' in this area, between the 60's and the 8's. I thought that ceiling mounted omni's, like Mirage might make a much fuller sound stage. I don't have the ability to add 2 more 8's as there is a fireplace on one wall and a formal dining room on the other. Also my wife doesn't want more speakers on the wall, we settled on two in-ceiling speakers. My main question, I guess is will omni's work well with my wonderful Axiom's?

arch, I'm not sure you'd see much benefit adding 2 more surround speakers in a 13 x 18 room.
Half of communication is listening. You can't listen with your mouth.

Assuming you haven't acquired them already and are itching to install them, you would probably do better to take a close look at your current speaker placement. You have plenty of speaker for your space. cool

Our rooms are close to the same dimensions, so 5.1 should be very enveloping and effortless in yours. Mine is 12' x 17'

First I will say that optimising your mains for stereo listening will create an immersive experience alone. wink So I recommend staring there.

Before doing any adjustments turn room eq off (audyssey, Mcacc, ypao etc.) Axiom speakers are relatively flat, so with proper placement you may not need "help" from an eq.

First move your front mains 2' off of your front wall if you can. The center channel will also benefit from getting off the wall. This should improve any bass null and cancelation issues-- while moving the soundstage forward.

Next look at speaker toe in and distance from your listening position. For my setup, the mains are approx 90" apart and my seating position is 13' off of the front wall. Experiment with messing with the toe in angle-- makes a huge differnce. Even a couple of degrees one way or the other will often make appreciable differences. Grab a cheap line lazer or pointer to align the speakers with your seat and track adjustents closely and listen. A string taped to the back of the speaker and stretched out also works.

Use a good stereo mixed CD to make adjustments. I used Mumford and Sons sigh no more for mine. The main vocals should be centered even though the center is off. It will give the illusion of a single singer surrounded by the band. Now that that is set, level your speakers using a bubble level on top (level sideways and front/back.) It makes a big difference with detail and transparency when your speakers are properly aligned with your ears and eachother. The rest falls into place-- as center channel and surrounds are easier to place.

You should get leaps and bounds better if you are out of whack.

Hope this helps. Why am I always so long winded?..... laugh

Arch, I knew nothing of that Emotiva feature, which doesn't appear to have excited much interest. A quick check showed that instructions here were to use direct radiating rather than surround type wide dispersion speakers. The proposed setup with Mirages doesn't sound promising. Properly located M60s and QS8s really should provide an enveloping soundstage, especially in a mode such as DPLII.

Enjoy the music, not the equipment.
