Let me first qualify by saying the more I read about SVS, the more I am leaning towards the PB2-ISD, but having said that, I must admit that before I ever heard about SVS, I was really interested in the sunfire line of subs... I try not to fall for the marketing hype around audio components, but I have heard and held the sunfire subs before and it's amazing what such a tiny little package can do... These things are built like tanks and the power ratings on them are absolutely sick (2700 watts)... Now there's a sunfire true sub signature on sale... I'd have a hard time justifying the $1300 asking price for this sub, but it does retail for $1999... Anyhow, just thought I'd get some of your opinions this sub???
