hello everybody, is there any significant difference between the two? they look very similiar, the main difference that i noted are the bigger side woofer, the blade 1 they go down 5hz deeper, nothing to worry about imho, and the coaxial is the same unit. they have different sensitivity but not a problem as i have good amplifiers, i saw the paper published and they have slightly different directivity on the orizontal plane, of course i am looking for an used pair, what would you get? an important thing, i think i will use the speakers paired with subwoofers , i should have some advantges with dirac , thanks!
