I am the original/only owner of this excellent 4-year-old sub. I am upgrading and need to sell. I checked eBay to see what the going rate is for Paradigm subs. I found a couple of PDR-10s that sold for $300 and $345 respectively. Considering that the 12 is a step up, I am asking $330 plus shipping. That seems to be a fair price. No original box or manual. Paypal accepted. I can e-mail you digital pics. Thanks.
