Good deal. I could never get mine to blend well with the mains cutoff at 80. Now it works fine. For HT, it does not matter, but for music I just could not get used to the sub reaching up so high. Big point here is the B&W sub may not be as good as the others mentioned here. I does its job, but I find its sweet spot is below 50.
