Thank you for the comments. I am married w/ children. The finished basement has a second system (Kef 104.2, Aragon 4004, Adcom GFP 750, Rotel CD coupled w/ an Adcom GSA 700 and TV/DVD. The room is large, but the house is older and the celiings are 7' at best.
Would room tunes or some similar treatment help the living room w/ the Martin Logans? Kinda stuck w/ system upstairs, and like listening in that room. However, I've never explored any type of echo busters, etc.
Thanks again.
