Looking into speaker upgrade/change?

I auditioned both the Aerial 6t and 7t and bought the 7t's because i found the bass extension better than  the 6t--however, i was listening to them in a room larger than the one in my home--a very good room--i couldn't be happier but would note that at least wrt the 7t, Aerial says the sensitivity is 90dB but according to measurements from reviewers it's more like 86-87 and they do need adequate amplification as many have already said.  Does your budget preclude looking at the 7t ? Your room size is asking for it.  I've never had to use subs-- I think the 6t's cost significantly more than the F208's but having heard both, imo the 6t's are also much better.
