I am soliciting input on placement of in-wall L/R speakers for a modest HT setup. My question revolves around whether putting the speakers closer to the TV but lower will be better than farther away from the TV but higher. Due to room geometry and positioning of an existing A/V component wall cutout, that is my tradeoff.
-- L/R speakers are in-wall BIC Acoustech HT-8W (link)
-- Center speaker is BIC VK6-LCR (link)
-- Surround L/R are also HT-8W. These are not optimally positioned in any sense, due to room geometry.
-- Sub is BIC VK-12 (link)
-- TV will be 55" Samsung (UN55D6300)
-- Receiver will be Denon 2112ci.
Room is 22 feet from TV wall to far wall.
Viewing distance is about 10' - 12' from TV.
Vertical viewing angle is approximately 10-15 degrees (bottom edge of TV is about 36" off of the floor).
Below, you will see the general proposed positioning of the TV (shown below with the display corners shown with blue painter's tape), and the possible "closer" left side speaker position (shown below with a speaker cutout template temporarily taped in place in the left position).
Originally I had planned to put the L/R speakers horizontally where you see the speaker wires dangling (see far right and far left, the latter is above the component recess). I came to my senses and determined that putting them vertically would be "better", but that entails bringing the speakers in closer to the TV. In this configuration, the maximum offset from the TV screen edge to the centerline of the L/R speakers would be about 16". This gives a centerline to centerline distance between speakers of about 7 feet. Is this too close together given the viewing distance? But is it better than having the speakers farther apart but horizontal?
The FIRST picture below is taken from the APPROXIMATE viewing position.
I also want to get some of your thoughts on the height of the L/R speakers relative to the TV and the under-TV center channel speaker.
