Do you like electrostatics? If so, consider either of the Janszen models. The controlled directivity minimizes wall and ceiling interactions, which is helpful in a small room. They sound great, too! --very low distortion and maximum transparency.
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!
