    I've noticed the SVS subs are available with different tuned port configurations. What does this mean?

    Will the 25hz version not produce sound under 25hz?


    [edit] Been looking at the SVS CS-Ultra, pretty good spec- 12" driver, 1KW amp, $1300 + postage & import duty (bah)

    Anyone own this model? Is it great for AV?

    What is the overall build quality like? (is the cardboard tube thin?)

    Thanks

    I just found a PDF on their site that explains the tuning.
    With simulated response graphs! Port tuning PDF

    I understand what the the curves show but not why the port tuning alters the response curves.

    I am now thinking that a 25hz tuned model would do all that I need and save me some money.

    Mat, I've read a bit about the different models- the 25hz versions will go louder, but not as low.

    Wheras the 16hz will go much lower than the 25hz version, but not as loud.

    I would say the 20hz model is the best, as most DVD's are in that area, and it only looses a couple of dB against the 25hz model (and possibly 25hz is a bit high anyway)
