I think someone like TTocs, Chops, or Twitch posted a video on a class on how to set up speakers using the guys technique that he teaches. I would like to keep that but I don't know where it is in the forums. Can you repost it for me? Someone contacted me for the info and I don't have it. Thanks for the help.

Speaker Placement Is King!

I'm in the process of once more proving this to be the case. I've been working on this big dip, no - not my buddy, a really deep dip between 60-70Hz that only shows up when both Large Fronts are playing the same signal. I go through the process of tweaking with no correction, then only after running Dirac does the dip show up. Dirac is only correcting "each" speaker, not multiples, so there's cancellation going on here.

I've played around with some absorption panels and some extra bales of rock wool and have gotten mostly minor improvements, but nothing that would indicate any "a-ha" moment. Today I did discover a half a-ha with placing one panel inboard of the Right speaker that is close to a corner, but then decided I needed to move the speakers first, something I have not wanted to do! But I did it anyway. So after a half hour I started getting some remarkable improvement!! The speakers are closer together - something I DON'T want but form follows function, and 7" farther from the front wall. I did no tweaking other than moving the speakers, then ran Dirac, and viola! (voila') the dip is less wide and a lot less deep!

Again, no tweaks to the subs or speakers, no room treatments, just moving the speakers. If Dirac is happy, then so am I. I use the Curtains in Dirac to keep the correction to below the crossover of the 13A's. I have yet to be happier with using Dirac on the stat panels, it's just not quite as "lively" sounding, but I'll take all the help I can get in the bass region.

I'm not finished, just taking a break, but wanted to post some good news.

That's excellent news! I'm still fussing around with the positioning of my 15's in my 'uncooperative' room. Since I think I've done just about everything I can (short of room treatment), I finally decided to start learning REW, and bought a mike from the guys at miniDSP. Arrives tomorrow so soon I should have a better idea of what is actually going on. As for how to fix 'my issues'... well, that is likely a whole different story... :D

I recently began playing with room treatments, specifically porous absorbers, really thick absorbers. Anyway, in the act of measuring different thicknesses, placing them here, there, and everywhere, I finally tested something I wondered about in the back of my mind but hadn't yet gotten around to doing.

Do the floor standing Width speakers cause any damage to the sound coming from the Main L&R speakers?

Yes.

They weren't causing any issues I could discern with frequencies emanating from the stat panels, they were causing problems with the bass. Those speakers just being where they were was worsening a problem I had set about to solve. So, I removed them. So instead of a 9.1.4 system, it's once again a 7.1.4 system. But it's the 2.0 that I care most about, so that's why it's such an easy thing for me to take them out of the system.

I bring this up because it has become more apparent to me lately that home theaters are better served by speakers built into the walls. This is something I've searched about and found info that supports my findings that when speakers are placed a distance from walls it brings unwanted interactions into play.

Width channels are a nice addition to an ATMOS setup because it brings another level of cohesiveness to the system. If I had a dedicated theater it is a no brainer to have at least the 9 bed channels. Oh well.
