Justin, for you it would definitely be the 180 with HP woofers but you may be able to get away with the standard 160 if you cross it over at 80Hz.

I have the standard 160v4 and I can't say enough good things about it. Every v4 I've heard is amazing. I have my 160 crossed over at 40Hz by the way.

The best way to get a hold of Ian is via email.
