Does anybody recognize this Polk powered sub-woofer? It's up for sale on an online classified ad board for $80.00, and I'm in the market for a sub. So I'd like to know the model number, year of production and anybody's opinion on what I can expect from this speaker. Any help/advice would be appreciated. The seller says it's an 8" powered subwoofer with 100 Watt Output.
I also found another ad for Polk Audio PSW10 for $100.00
Which is better? I currently have a pair of RTi4's, with a new pair of R50's on the way.
