Holy bshiznit that exhaust was loud! The fact that you claimed resonable HP (not 650) automatically gives you a thumbs up!
What generation are you talking about? V1 or V2? Just remember, the v1's are 12 yrs old! The v2's look nice and have the same model #, but I don't think they are much better than the w3's. This is my experience as an Installer, and acually playing with the stuff. I was accidently "boinking" one during tuning. It was in a sealed enclosure with a 500/1. This shocked the crapoutta me! The Treo subs just flat out perform above expectations. I would recommend a single tsx 12 in a fat ported enclosure. Say hello to 30 hz.
Yeah man, I'll mmake yyour ttrans aam hhuurt yyou!
