This thing is a BEAST! Great build quality, super low extension, clean bass. Love the fact it comes in two pieces as I am on the second floor. Moving this up there in one piece would have been a chore. Love it so far.

So far so good, currently running it with all four ports open. at this time we are still in the tuning and testing phase of things but i will say the bass is tight and we have no regrets.

A magnificent beast!
I love this thing! It seems to me that it easily blends into about any system if you configure it properly (quite easy in fact), but oh boy can it crank. I have never experienced anything that hits this low, fiercely and cleanly for a home audio product. Not a one note bass generator, this is a truly capable subwoofer. I have absolutely no regrets about the purchase, and will probably be picking up another for my standalone hi-fi system. For that , I will just need figure out the proper placement so my records don't skip.
