I own the P3esrs and have them in a 20x15x8 size room. I have owned the 7s and IMO the P3s are better . Since you are using a sub I doubt you would need anything more than the P3!
Harbeth Question
I own a pair of GR Research H Frame OB subs and i want to purchase a set of Harbeths to go with them. I was thinking of getting a smaller unit that can sit atop the subs. Since i dont need bass out of them I was also thinking I dont need the largest system they sell. Any thoughts/suggestions on model? Do you agree with my logic? Thank you.
