room setup

Two feet behind the front may be OK -- let your ears be the judge of whether another foot or two would improve things. For when you do some serious listening, you could try throwing an acoustic blanket over the TV -- it's a lot easier than moving it and may give you OK results.

OK. Let's see. A 32" TV you say? (diagonal?) And let's say the front face is represented by a 32" dia. disk. 32" is 2.6 feet. If you let that dimension be the length of the half wave it will reflect, then the full wave dimension is 5.2 feet. If you divide the speed of sound (approx. 1100 ft./sec.) by 5.2, that would be a frequency of 211 Hz.

The TV will be essentially invisible to any sound below that frequency, since it won't reflect them, and as for sounds above 211 Hz, unless you're using a dipole/planar type speaker, there probably will be minimum reflection, since most frequencies above 211 Hz (and certainly above 500 Hz) will be projected forward.

Switching to front projection was the second best thing I've done for my two channel sound.

A blanket on top of the TV would kill high-frequency reflections, which aren't a real problem because the speaker is more directional at those frequencies. It won't do anything for lower frequencies which are hitting it.
