    I'm aware of specialty subwoofer cables (line level) available on the market. I assumed that a quality audio interconnect would suffice for this purpose. After reading some other commentary on the subject it sounds as if a higher resistance cable may be more ideal for this application (say 75Ohm). What is the ideal cable for the line level input on a sub?
    Thanx,

    For the "ideal" signal transmission between 2 devices, you want the output impedence of the source and the input impedence of the destination to be identical, and use a coax cable with the same impedence.
    This becomes important as 2 things increase:
    - The frequency increases
    - The power increases
    Neither of these tend to be an issue with a sub cable because:
    - Low frequencies are involved
    - The signals are line-level/no-power
    The sub-woofer system, with the much-lower frequencies involved, it's less of an issue to impedence match.
    So buy a quality sub-cable based on build-quality, to match your other cables, etc., but dont spend tons of extra to go high-end in the product-line. You wont get any sonic improvement from the extra $$.
    Hope this helps.
