I'm moving into a new apartment with a main living room sized at 12' x 22'. I'm curious if the Harbeth p3esr is too small. McIntosh MA5200 100watt amp. I would love the HL5plus. I've heard and loved them, but I'm afraid those might be overkill for the space -( not to mention the wife factor.)
you have quite a big room. I wouldnt recommend for such a big place. if you have the budget, stretch it for a used C7.
My room is about that size and I have no issues with my P3s and a REL sub. My couch is about eight feet from my speakers. The floor is carpeted. I think it sounds fantastic.
