Many here may believe the unorthodox design of the 180 won't work across a wide width of seating positions. The 180v4 however is not like the 150v2 which did indeed suffer off-axis.

I've heard both in v4 and both sound very good. The only reason to go with a 180 is if you need more SPL. I loved my 160v4. With active LFRs, I don't need it.
