DO NOT BOTHER WITH THAT SUB!!!!!!!!!!!
Take it from a guy who owns a E250P with a 12".. Now this one is ok.
The E150, will bottom out very easy....AND WILL DISTORT AT LOW VOLUMES
I have demoed it.... DO NOT BOTHER.
The E250 is great, it is not boomy as most people state about consumer line of JBL. I have given small reviews of it here at Audioholics, I can point you in the direction of those posts if needed...
You can get the E250 for
$232.00 shipped to your door. From a authorized dealer...
EDIT::: Here is a link you can get the E250P 500Watt 12" sub with a Frequency response of 25hz to crossover selection (80,100,150,200Hz Basically variable 25hz to 80-200hz)
