Excerpt: I bought two of these subwoofer's in a sealed enclosure and was immediately impressed by the bass they produce. The subs have always from day one produced good quality tunes. This was until the rubber surround seperated from the cone. It did not tear but the glued literally came undone. I had just passed the one year warrantly by 30 days and the seller said I had to purchase another one. I was not impressed with that at all.
Conclusion: These are fantastic subs. I have two in separate boxes hooked to a Polk 5 channel amp with 500 watts going to them at 2 ohms. They are tight and clean. I highly recommend them to anyone buying a sub.
Conclusion: This sub is the ultimate in performance. It gives you fat bass and serious lows down to it's Fs of 31 Hz. High quality sub, good surround, large magnet, and nicely built for producing bass notes. does not require much of a big box but you'll be surprised with the output that you get from this sub.
Conclusion: I replaced my two rockford fosgate 12" p1 subs with these and these out bumped them by allot!!! clean hard hitting bass!! have them running on a jensen 900 watt mono amp and these subs hit hard!!!! GREAT BUY!!!
