Which Harbeth?


Based just on room size which Harbeth would work best, Compact 7's or P3esr's?
Room is 18x11, 8 ft height. Moderate listening levels.

Thank you

Just wanted to say THANK YOU very much to all who responded.
Very helpful to me indeed.
My 5 cents with Harbeth SHL5 is that room treatment on bass a must as I found they will relflect the room's acoustic more than other speakers.
An interesting assumption, Luna....how many different rooms have you tried a pair in? I totally disagree. but that's me.
