Man this is really murky water on this subject. The thought of a line array with inexpensive surplus drivers has really got my attention. I'm thinking 8 4" Peerless Mid-bass with 8 1" titanium domes (only 2" overall diameter) in close proximity to each other on convex open baffle with stereo subs of 2 10's each. I can purchase all the drivers for a stereo pair for under $500.00. All the negatives on the subject of line arrays from 'audiophiles' really confuses especially when i look at McIntosh's line of speakers. Any thoughts ??
