Thanks, Curtis. I think you may be correct about the rolloff. I have not heard the sound enough to duplicate, so, I'm thinking it probably isn't speaker. I'm thinking of redoing everything. Maybe you can help.
I've measured my room. I saw someone do a map layout, it that will help.
I'm beginning to look at options...I'm leaning toward the Denon x4000. What do you have, if you don't mind?
I'm also thinking of possibly the upgrade to sierra 2...but, what all does that include?
I'm thinking of a sub, but, don't know if the one on sale is the right one. I'm open to all suggestions.
My room is: 23'3" x 17'x 8'...is that enough info? I think the map thing will help.
