UPDATE: just installed the vp180.. what a difference from the vp150 v2.. thanks for the advice on that, really worth the upgrade
need to know about subs... has anyone compared vtf-3, ultra-13, and ep500
what about 2 x ep500
Happy you're happy!
If I'm not mistaken, I believe Jay (jakewash) has compared the PB13-Ultra and EP-500. He's unfortunately not around as much, so you could try sending him a PM.
Inquiries about comparisons between the two aforementioned subs are quite common. Maybe one of the guys here will be able to provide you with a link to an old thread.
