Amazing Sub Woofer

I bought this for my house and am blown away with its performance. I have very high expectations, but this just took it to another level, in fact I see myself purchasing a 2nd one. I don't like my neighbors so with a 2nd one I should see for sale signs going up soon. One note for any of you that are installing this in your home, you will run into a problem if your trying to run it out of the back of your AVR, the signal to the sub will not work as it is not strong enough. I had to purchase a small mixer, ran the sub ouput from my AVR to the mixer, and a 1/4" jack from the mixer to the Sub. Dont use a XLR connector is it is a balanced cable and does not work as well as a 1/4" unbalanced as I had to plug it into a RCA jack in my wall which is unbalanced as well. With the mixer this sub just flat kills it. It is amazing and I highly recommend it. 5 Stars.
