I'm looking at using an AT screen with speakers behind and can't make sense of the geometry based on the guidelines I see. The SMPTE guidelines are for a viewing distance of 1.86 times screen width, which gives a viewing angle of about 30 degrees, and the THX guidelines are for a 26-36 degree viewing angle, so they are pretty similar. But recommended speaker listening angles are around 45-60 degrees for home theater (maybe less for 2-channel). In practical terms, for a 120" diagonal screen the viewing distance would be around 16 feet, and the listening distance would be around 8 feet (to keep the speakers within the 105" width of the screen). I understand some compromise from the ideal is OK, but this seems too far off to compromise. For a normal screen the L and R speakers would be outside the screen edges, so the optimum ratios can be met for both video and audio. What am I missing about using an AT screen?
