I was very skeptical when I first bought this subwoofer. Normally I buy brands that I recognize but I happen to be at the Ground Shaker store and they let me sample a a few cars and trucks that had them installed against other brands. I could not believe the sound pressure and how clean the bass was. They compare right along side with the JL Audio W6 subs but actually a little more poweful. I have listened to this sub both in a sealed box and a ported box. I can guarantee you that in a ported box the bass is overwhelmingly powerful. With just one subwoofer in a ported enclosure, I waited 1 month to fully break the subwoofer in properly; I then cranked the music to max. I'm pushing the subwoofer with a Procision Power 2000 watt amp with 1000watts RMS. I was afraid I was about to shatter my windows! zero distortion so I am very impressed with these subs.
I have an Orion XTR PRO sub also, and hands down these subs are more powerful!
