They are great, a huge upgrade over the pair of 8 inch Yamaha subs I have. I put one in the right front corner and one in the left rear and use audyssey on both at the same time and it works quite well. I have considered getting a antimode but am really happy with the way it is right now. I find the bass to be taught and refined , very musical. That's not to say it they cant bring the house down . Honestly 1 of them would have been more than enough given the size of the room. The woofers have XBL2 tech ,and are supposed to be the greatest thing though I don't have proof of that . I think they are the best compromise between ported and sealed and the passive radiators are adjustable.
