I have a room about the same size as you do and the Legacy Audio Studio HD's work GREAT....I actually have compared the Legacy to KEF and the Paradigm bookshelf speakers and found the Legacy performed much better. The Legacy are some what heavier (about 32LBS ea) then most other bookshelf speakers that I have looked at. Frequency range is listed at 41-30k, with 91 db. This is a 4 Ohm speaker which can be order in multiple high grade finishes and it won't " break the bank " while doing so.
The best speaker for a small room...at any price point.
I am wondering which would your choice for the best sounding speaker in a small dedicated room..say 10'X11', or maybe up to 11'X13'? Assuming that budget was not a factor!
