Speaker distance and tow in?????/


My room is big / 18x30. But due to arrangement I can only bring out my speakers 2 ft from back wall..... side walls not an issue. My 2 main L-R are 8 1/2" apart ( center to center of speakers ) . How far back should my seating be? I "think" there is some "basic" math to work from for far field seating. In my "near fields" it is all equal.... as a rule of thumb. Tow in is another adjustment. I am just looking for some "basic" good info and hope I don't start something... You guys have spent a lot of time on these issues..... and I am glad to have your suggestions!

On one of these august sites I read advice on toe-in that I've found works for my KEF 104/2s: Aim the speakers at half the distance between the prime listening location and the rear wall.

My room is about 14' by 19', and the front of LR speakers are about 4' from the wall behind and 3' from wall to the side. The listening positions are about 3/5 of the room length and centered laterally.

The best rule of thumb I know of is the speakers and seating should both be at i/3 the room depth. If that is not possible 1/5, 1/3 works. The next would be 1/7….
In you 18x30 room I assume your speakers are on the short wall, thus you have a little under five feet to each side wall? If this is true the 1/3 dimension is 10’. Meaning the best would be to start 10‘ to the speakers and 10 more to the chair. As you said, this is not practical. The next best is the speakers at 6 feet from the back wall to the tweeter face. This would still provide adequate soundstage depth. If this is not possible, the 1/7th dimension is 4.2 feet. If you need to go even closer keep trying the odd factor of dimension.
As per toe in, start straight out and test it. Keep toeing in until the center image becomes clear and defined. Small amounts from that point will allow you to tune it closer, making a solo vocalist’s mouth appear the correct size.
No... my room is for math..... 18x24 with my speakers on the 24" wall. My room is all angles and wraps around to the kitchen and on the 24" side is dining room. I have a semi cath sealing and a tre ceiling in the dining area. I don" think I have a side wall problem or the "box" type room that gives that kind of problems either. I have what I guess is called a kinda great room. Like I said..... my speakers are at 8.5 feet apart..... I am going to have to live with that. I guess it's just a matter of "WORK" to get it to sound the best I can.
can you place your seating area (ear) 12' from the speaker wall? That's where I would start, giving you a greater distance from the speakers that they are apart. the ceiling and angualar shape will help in many regards, but the 1/3 rule will still give you the best starting point.
If pulling them further out into the room is a problem, I would consider a different brand of speakers. A friend of mine has NHTs and they like it close to the wall.
It's either that or....how long have you been married?
