Nah, it is a 15"  sub.  I believe it is discontinued right now though.  I was really looking into this guy as a sub before I moved.  Now it is on the back burner for a while but this is the top contender.  The specs I finally got as official from a dealer up here in Canada say that this sub can hit 23hz with real authority and that it weighs 53lbs.  I was talking with Mcman about this guy months ago, it was going to be my big secret.  Thanks a lot for spoiling it Buck 

 .  JK.  This sub really seems like a bargin but I would have to get it sight unheard if you will.  I have pushed back the sub purchase for a while.  My new TV room has breathed some life into what I used to think was a very anemic 10" polk that I'm currently using.
