I bought this subwoofer from a local dealer for 69.99 and i must admit for that price i was a bit skeptical. I have owned this for about 2 months now and love the sound quality it produces. You have to take in mind this is a base model. This subwoofer is also one of the subwoofers made in china. I owned a w7 and a w3 before this and they were both american made. But still for the price this is still a very good subwoofer, but if you have the money i’d recomend the w3v2 over this for a little bit more money..

So i purchased this sub with the sole purpose of installing it on a Home Theater Subwoofer enclosure. I am currently only using a 100w plate amp until i get the 200w one, but i must say WOW! This sub was able to reach 107dB on a 1.88 cu. ft enclosure. The subwoofer is not tuned yet. currently is tuned to 33hz, but when i increase the ports, i shall be able to go to 28hz with no problems. The construction of this speaker is just impecable. It looks hot, and the sound is solid. Best $89 i spent on a subwoofer. I would recomend it. JL subs have never failed me and i have used them for over 9 yrs.
i was debating between this and the Infinity 1250w, and i am not sorry about my purchase.
