I have just finished my home theater and looking for some advice on potentially changing my surround speakers to Image S50's and also some guidance on their placement.
Briefly, my theater is 11' x 15'. Equipment as follows:
Panasonic PT-AX100u Projector (1280 x 720p native)
120" Diagonal Fixed Frame screen
Onkyo TX-SR705 Receiver (3 HDMI In, 7.1 capable)
Oppo 981HD Upconverting DVD (will be replaced by Panasonic DMP-BD50 Blu-Ray when available)
5.1 Speaker Setup as follows
Fronts PSB Image 4T
Center PSB Image 8C
Surrounds - PSB Image 1B
Sub - Subsonic 6
I've had these speakers about 6 or 7 years and I'm very happy with them.
It's a somewhat tight space, I only have about 2' behind the couch and about 3' in from the side to the sweet spot (right seat of the left-hand loveseat). So I have my surrounds 1B's in the rear corners about 2' above ear level. The result sounds very good but I'm wondering if I would see significant improvement in the rear sound stage if I switched the 1B's for Image S50 bipoles and mounted the S50's on the side walls 2' above ear level and as far forward as possible (that will only be about 22" from the rear wall because of a large opening on the left wall of my theater).
The attached sketch shows my current layout and the RED X's toward the rear of the sidewalls shows the proposed placement for the S50's. From there one of the speakers in each bipole will fire across the seating area and the other will reflect off the rear wall and then across the seating area.
I've also attached specs of my more vintage Image speakers. They are very similar. My Image 4T's sound very similar to T45's.
Please let me know your thoughts.
