Gotta Say, that I was not wholeheartedly impressed with the eD drivers SQ.
Never heard the Quad Drive yet.....
Accuracy of the Fathoms is amongst the best I've heard but they certainly aren't going to fill the room or hit the low notes like the other suggestions.
What is the size of the room and what are your goals here...? HT or just music or what.....
Too many people like to just throw out suggestions without getting more info.
More info please
