Okay, I admit it. Reading your link initially made my eyes glass over and I am normally a pretty smart guy. Then I hunkered in on the details and before you know it, I was on a step ladder with a tape measure and calculator trying to visualize sound waves with the obsessiveness worthy of medication. Then my wife caught me. HA! I am not a true audiophile. I just want my surround sound system to sound as good as I can make it within reason and yup, laziness. At the same time, I so appreciate the ears of those with a more discriminating taste in fine audio quality.
My dedicated mini theater is a 14' deep by 15' wide (and 9' ceiling), with doors and windows making it illogical to place the couch anywhere other than up against the wall that it is. I have four Polk RM8 satellite speakers available to use for side/rear surround sound units (with Polk RM 7500 front speakers and PSW350 subwoofer). The RM8's also have Polk's wide dispersion array feature, further "deepening" the sound, HA, at least as far as my marginally trained ears can tell. My idea was to buy in-wall speaker covers for two of the RM8's and set them in a larger custom built cavity either directly behind the main seating position or more laterally. This would at least give some distance to work with; 18 inches normally and maybe 36" if I moved the couch out from the wall when I really wanted better sound effects.
So, I know that you want to boost my Volkswagen Beetle to the performance of a Ferrari, but can you (or anyone else reading) just help me make the drive to the store relatively efficiently?
