Help with room treatments


I have alot of glass behind my speakers and also a TV between (see - beauty and the beasts under systems for pics), yet my system sounds great to me. The speakers are forward of the TV by at least 8 inches.
After hearing all the stuff here about room dynamics, today I placed very heavy blankets over the windows behind and also over the TV to see if acoustic absorption panels may give me better sound. I did not hear any differences on several of my favorite test cuts in near field listening.
Could it be that my SRS-SDA Polk speakers are better than most at eliminating the reflections given that they phase cancel signals coming from the left speaker to the right ear and vis versa for the left ear?
Or am I that untrained to hear differences. I think I have good ears, am a musician etc. Perhaps I picked up very subtle increase in the solidity of instrument placement. but that is all I heard.
Comments?

first, nice set-up and beautiful room.....that looks like a great place to listen.

you have a few things going on there.

the two biggest influences on your sound are the TV and the ceiling......neither of which you likely want to fool with. if it is not too heavy, try listening without the TV.......or try covering it with a blanket. another consideration would be some sort of tapestry that might hang from the ceiling to eliminate first relections.

if you do remove the TV, NOW those blankets over the windows may have much more effect. the solution i would recommend however would be a pleated window covering from Hunter-Douglas called Duettes......which will break up reflections without over deadening things. these can be lowered and raised so they will blend into your window casements and you will barely see them.

you will not believe the effect of controling the ceiling relections.....maybe experiment with some towels or blankets.

your speaker design, where the front baffle is very flat and broad, actually is helping by reducing the backwave toward the window of mid to high fequencies. you pay a penalty in perfomance compared to a narrower baffle but get the benefits of the reduced reflections.

overall, your speakers are far enough away from the room boundaries to sound pretty good.

good luck.
