Chris, I have an active crossover for that purpose. The overall system efficiency is about 88-89db. I have been known to play at realistic orchestral levels at times (90-100 db). The room is L-shaped in the rear and the length is about 25-27 ft with a 7-7 1/4 ft ceiling and the width is about 15 ft but there is an enclosed staircase on the right which reduces the usable width to about 12-13 ft. No need for balanced connections. As far as biasing is concerned, putting a screwdriver in a slot is as complicated as I want to get. Also I am 6'5" tall and about 300 lbs so crawling on the floor behind some amp while balancing some screwdriver and meter is out.
AudioK, I have a pair of Sforzando JL1 speakers. They are wonderful. Here's their website.
