When the pair of W3s arrived, I took them over to Lees (koiman) house and compared them to his pair of M3. To me they were so close it was diffacult to tell the differance. Once I installed them in the wall, the base was even more defined.
The blind test up at Axiom was very close between the two speakers, to me, both are good choices. In my opinion if you limited floor space, try the AS series, I doubt you will not be happy with them.
