Finally got my Polk PSW10 Powered Sub delivered to the house today. Debated buying a FF or PP speaker kit but finally decided to go with a powered sub instead. Mainly so I could keep the sub whenever I trade pins in and out. Anyway, so I hooked it up to my Met Pro and NGG, and I must say I'm very impressed. Changes the whole gameplay experience IMHO. If your on the fence about trying one of these, do it!
