The bass and overall clarity improved significantly with the modification in my opinion. I did them one at a time and did A-B after the first was completed.
The big speaker in the right hand corner is a jbl 4648 that I introduced for the home theater. It adds a lot of "mid bass" frequencies. Right now I have the two systems completely seperate (2 channel vs HT). I think the 801s have the potential to make good bass, and would rather not keep adding more big speakers :)
I am intrigued by the room treatment ideas, not sure how I would give a treatment to the vaulted ceiling? I can certainly move them away from the wall some, and I have heard getting them up off the ground (with some stands) helps too.
I really don't sit in the chairs to listen, this is our "community room" and lots of time spent there working around the kitchen/island.
I will try moving them away from the wall, closing the drapes, and maybe nocking together some short stands out of 4x4s. I have read that they like to come up around 3-4 inches.
thanks for the input!
