room too small for a 92" screen. Not much space left to position spkrs. I would rather go for smaller screen. If it is indeed a 10' x 10' sealed room with a ceiling height of about 10', TS will have acoustic nightmare even with THX system mentioned above.

Does the room size come into consideration when determining whether to go for a 5.1 or 7.1 setup? If yes, then what size is required for a 7.1?

Yes, if the room is not long enough, a 7.1 system is not feasible. Ideally, the rear surround should be a few feet away from the LP.

There are differing recommendations. Some recommend to have the tweeter of all spkrs at same level while the general and more common is 2ft above ear level.

I am not following the 2' rule.
I put mine at 30" height (following J-29 specs).

If the setup is in the living room that also opens to the dining area; common in all link houses, is it advisable to go for the 7.1 system if there are say 3-4ft behind? Or should it be just 5.1? hmm.gif

Err.. 30" is 2' 6". If 2' above ear level, the stand is a bit too short. When seated, our ears are about 2' 6" to 3' from the floor (depending on sofa and listener's height). I am using 4' stands for my surround.

In this instance, the rear surround can be considered since it is long enough with ample space.

The problem in a small room is lack of wall space to hang up surrounds/back speakers. When I started off HT, I initially followed the 2' above ear level rules as a guideline. But in the end what I did was to keep on repositioning them at different heights and listen from the listening position. . The final position is the one that gave me the best full bodied and ballance surround effects smile.gif . That is what I did. My current surrounds is 1' to the back and 2.5' above the ear level. nod.gif

Back surrounds should be at least 4' from LP for optimum dispersion.
Having back surrounds too close would have localisation of sound.

Mine dipole is mounted 2m above the floor with 8 feet apart while still within the front speakers spacing.

There're some dipole speakers can be triggered to be monopole or bipole for different type of materials you're listening to brows.gif
