I finally installed Acoustic Panels from ATS Acoustic Company.
And my home theatre does sound better than ever. I can hear sounds that I did not hear before; for examples, in "007-Royal Casino" movie I heard crickets making noise in the background at one of night scenes that I did not hear before, or such subtle sounds as a deck of cards being dropped down on a table. I felt like I was actually there with the actors at the scenes. The overall atmosphere feels and hears more like in a real theatre than ever before! I think it was worth the money spent to have treated the living room with these sound panels. :)
I want MORE to be COMPLETE!!!
These acoustic panels really made such a huge difference in sound quality beyond any of my expectations that I am seriously thinking of spending more money for more bass traps next time. I am very happy with the improvement I experienced with these acoustic panels; so I am sure that there is still a room for additional improvement in my Home Theatre sound quality. It will take me another two months to get more though. This time, I will get from GIK Acoustics because they have ones with stands that I need to place in front of curtain areas so that I can move them around in case I need to get out to the balcony. And I will also get one RealTrap Tri-Corner for the front upper left corner for the look and bass trapping. :D
And, I know that my cables can't get any messier-looking, and my living room is actually carpeted. :)
