Great sub, truly in a class by itself. Only reason I am selling it is that a found a great deal on a bigger SVS sub and couldn't resist. No need for two massive subs (according to the wife ), so I wanted to offer this to the good folks here first. You can peel any info you need on this beauty from the website: http://www.svsubwoofers.com/subs_pcplus_20-39.htm You can read some 3rd party reviews here as well: http://www.audioreview.com/Subwoofe...58_2741crx.aspx Sub is a hair over a year old, it's fully broken in but I've never had the gain over 1/2 and never really approached the limits of what it can do. It is in near perfect shape (little dust?) and comes in original box (with ship padding) with power cord and port blocker installed. Don't have the receipt, but it is still under warranty for 2 years (SVS is very good about this) and I am the original owner in a smoke free home. Asking $650 shipped to anwhere in the continental USA. Don't want to send to Canada, customs for this would be a pain for all parties involved. I want to offer this to the good folks here first, in a few days I'll post it to Audiogon (and then it will be GONE.) So let me know if you have any interest with a PM ASAP.
