Speaker placement along the long wall


Does anyone have any experience with speaker placement along the long wall? My room is 15'Lx12W. The rear of the room has a 6' wide opening into the dining room. This allows me to seat in between the two rooms (about 10' from the speaker right now), though it remains domestically unpopular. I'm considering relinquishing the space between the two rooms by moving the speakers along the 15' wall. The only problem is that I'll have about 8' from the chair to the new front wall, thus forcing me into near-field listening. My speakers are sealed box design(Hales Rev3). I'm wondering, before I attempt to re-arrange the living room, how close to the rear wall can these speakers be placed with minimal change in sound quality or any other pros&cons.

Responses are much appreciated.

Gentlemen, thanks for all the encouragement/insights. I moved the speakers last night as a trial and I'm quite surprised by the result!

I placed the speakers a foot away from the wall and 7' apart (inside edge-to-edge) with a slight toe-in. I couldn't believe my ears! Much better left-right staging and precise image localization. It felt like I could reach out and grab any particular image. Oh, the thrill of having Leonard Cohen's larger than life presence in between myself and the speakers! I only listened to two CDs last night but I'm sold on the long wall method.

Some other observations:

- Lack of soundstage depth -- doesn't project out behind the speakers that much. May need to pull the speakers out a little.

- Increased bass response. May be it is all real and I just had a null before. Or, it may be the distance/driver-integration that Tim pointed out.

- I lost the dog! Amused to Death by Roger Waters, which is QSound encoded, has a dog barking behind you. In fact, the album projects a lot of images behind you. I seem to have lost all that. This is probably due to the fact that I'm seated next to the wall as opposed to in the open between the two rooms.

Looks like I'll be busy this weekend optimizing the new set up. Thanks a lot to you all.

P.S.

Bob, you're right. It even sounds better in the dining room.

Rives_Audio, I'll check out you website.

Sean, I also have a distaste for ported speakers. I can't give an educated reason for it though.

Nighthawk, this change was necessitated by demands of unobstructed access to the dining room.

Unsound, the Hales manual, though very detailed, is a study of Fields and Waves in itself! I haven't looked at it in a while, but I don't think it covers long wall placement.
Sol322,

The dog effect is on track#1. You really have to increase the volume a bit to hear the first dog effect behind you right at the start of the track. Sometimes later the dog moves to the right and the barking is more pronounced. A lot of people miss the first dog effect since it's level is much lower than the second one. There was a thread on this a while back: http://forum.audiogon.com/cgi-bin/fr.pl?cspkr&1015691388&openflup&1&4#1

BTW, do you get the old man monologue on the first and last track placed squarely to your left? Same for Merv Albert talking on Perfect Sense 2.

The speaker wall is completely bare. I may consider a thick wall rug or something. I don't think I'm allowed to place tube traps or any such materials.
