I finally got around to mounting my Polk Audio RM101 surround speakers at what I think is the proper height, roughly a foot higher than ear level from my listening point. I also raised my LF/RF speakers about 4 inches, putting the highs and mids at eye level to where I sit. I don't have a sub, just the CV speakers. While waiting to sell a few things to finance a properly matched center channel speaker, I wired my two older KEF K120's together, connected them to the center output, and placed them directly under the television.
After doing so, I ran the system's set-up again with the microphone literally sitting on a tripod, on top of my head. I know, it sounds odd, but it worked!
I now have a system where I can't hear where the sound is coming from any one point, because I'm fully enveloped in it. I've heard bullets whizzing by my head on each side, heard a knife thrown on my left side, and a monkey scream on my right.
I'm currently watching "The Rundown", starring Dwayne Johnson, and have had to turn the bass down twice, because my windows rattled.
Yeah, I know there's systems much better than mine on this board, systems with more power than mine, etc., but mine was mostly financed by selling items I already owned in my house...so I haven't had to put out any cash from my wallet other than speaker wire.
I'm a happy camper.
