    I'm not sure I would. Usually, the best place for a sub is not where the speakers are located. If I wanted a floorstander...then I would get a real floorstander.

    That said, a floorstander from Ascend would be interesting.

    I got about the same answer from Dave regarding an Ascend sub. Something along the lines of while he's designed subs in the past with the SQ for the dollar of Hsu there isn't any real reason for him to do a sub.

    I own the HW and SW to do this, but I know nothing about how to properly make this measurement. Maybe once I learn more about measurement, I can check out the decay and other aspects of subwoofer response.

    OK Brad....we should put a deadline on your learning.

    No measurements from me tonight...I played tennis for a couple of hours and I'm pooped.

    So Curtis.....

    Why'd Hsu say that the BFD may not help you? It should, at the very least, help flatten out any peaks. Nulls are a different story, but you may not even notice the one you have.

    I'll have a little time tomorrow to take some quick sound levels with the latest test disc(1Hz increments) and get better resolution.

    Because I really do not have any nasty peaks.

    Yeah, with the exception of that canyon, your response is pretty decent.

    Did you use a mode calculator to see if that frequency matches a room mode and which one it matches? That might be helpful in investigating room treatment options.

    That's an understatement! If Ascend came out with a speaker whose frequency response extended down to 35Hz or so, I think I'd take a pair without waiting for reviews and without asking about the price. Hope you're reading this, dave f.

    Nope...have not done the mode calulator yet...I will. I have to finish my taxes!
