impact of room treatment

dodge Im in the same boat. I have to consider looks and function as well as sound. Luckily I have a pretty understanding wife.....so far.:)
I just ordered a swatch pack from ATS ACOUSTICS. They have several options of material to cover panels, traps, or whatever you go with. You can customize them with art or photos for extra $. They seem reasonably priced as well.
I have tile floors and the right side of my living room opens up toward the kitchen. Is the open area a plus or negative??

So it seems the first course of action is to treat the first reflection point?? How big should panels be?

I was using also Acoustic Revive products panels with very good results in my room for different set ups. Easy to place and very good looking wall treatment...they are stand or hang, so you can try them on any wall.

Ready Acoustics have very effective and good looking panels at a reasonable price and give free advice. My wife actually told me to buy some more of them; enough said! You will not believe the difference good room treatment will make.

I use Ready Acoustics also. Helped my sound tremendously.

I have several ATS Acoustic panels in my room. The company has been great so far for me with quick shipping and quality build. One of my panels is a custom order which the web site says may take a bit longer. This custom panel arrived as quickly as the other panels.
