I agree with Latik regarding the Tannoys. I use 12" HPD drivers (dual concentric from 1975) in my large listening room ( 16' X 34', with cathedral ceilings). They are in custom 150 liter enclosures that are built on the massive side, at nearly 2" in thickness, and 192 lbs. each. Situated on the end wall though, but boy, do they do the job!
