What an interesting thread this is, I have followed this one from the beginning. Some excellent points have been brought up, mapmans last post is spot on IMO. As for my speakers I own a pair of Gedlee Abbey 12A speakers that use a waveguide along with a 12 inch woofer, I also employ the multi sub (4) approach that Dr Geddes advocates. Best sound I have ever had in my room.
