The W0's are hard to beat for the money. These things absolutely knock. Sold a couple of them this week to different customers that didn't even come in to purchase subs-just can't believe the sound for the price (happens all the time). Everyone just assumes that JL still only offers really expensive stuff. W0's are the best of both worlds. JL struck gold with this one. They are projecting this to be the best selling subwoofer in America by the end of 2010. They might be right...
