Speaker placement for 2-ch AND 5-ch same room

The screen is retractable, which helps a lot.

I was trying to figure out how to get the 2-ch and 5-ch together in one - in fact, that was my original intent. But tube gear generally is not good with remote controls, and useability of the 5-ch stuff is CRUCIAL as my wife is simply not going to fiddle with more than one remote. In fact, at the moment there are three buttons to push and this is nearly ruining it! If I separate things, then I have an easy-to-use solid state system for movies and an old, muzzle-loading analog tube system for music. The common components are the room and the subwoofer. I was astonished to find that the Descent has provisions for this sort of thing!

Anyway, I'm asking now because the room isn't built yet and I'm more than a little suspicious that my current temporary room won't let me evaluate this. (It's 13x14x7 - can you imagine that with 7 speakers in it? Especially with the Odysseys 4+ feet from the 14' wall?!?!) I should post a picture of it - it's a riot, but all I have until the addition gets built.

"Necessity is the mother of invention" and "Where there is a will, there is a way" come to mind. With 7 speakers in the present room---I'm betting you'll be going for 9 in the larger room.PS, don't forget that extra center for the rear;for "pro-logic-2".

Blw, with the "remote" constraints, I can only say that you have done a masterful job managing the situation. You still may wish to experiment with moving the HT front speakers later (i.e., away from the main speakers when playing music and then back again for HT -- see if it matters and find a simple, wheeled?, way to do this if it does), but apart from that, it sounds like you are far from nuts.

Here is some food for thought,before speaker placement issues,note that your dimension of 15x21x9 have a commom denominator of 3,meaning all dimensions are divisable by 3.When this occurs(all dimension having the same common denominator) there is a chance of peaks(boosts) and vallies(suckouts)at certain frequencies do to the room dimension excessively renforcing each other.Is it possible to stretch the room to 16x23x9 ? I would contact Audiogon member RIVES,and run it by him.I may be overracting,but an ounce of pervantion is worth a pound of cure.
Good Luck

Davehrab is correct. Dimensions which are exact mutliples do tend to reinforce or boost the same frequencies and create dips in some others -- in a 9x15x21 room, those boosted frequencies are at 188 Hz and 377 Hz with some fairly big gaps or dips in the ranges of 81-107, 161-188, 188-215 and 269-296. If the dimensions are off a bit (e.g., 8'9" rather than 9'), it will affect these in a relatively positive way. My understanding is that anything above about 300 Hz is not a big deal so the only real peak is at 188 Hz and that could be managed with specialized treatments. The 27 Hz gaps might be a bit of a stickier problem. Rives knows more about this and will undoubtedly have more to add. Feel free to ask questions though and I'll give it a shot as will other more learned Audiogoners. Good catch Dave.
