    How many times can an analog output (subwoofer) be splitted without loosing quality?

    Hi James, this isn't easy to answer as the answer depends on these factors:

    a) the output impedance of your pre-amp/av-processor
    b) the current drive capability of the pre/av
    c) the input impedance of the active subwoofer
    d) the screening quality of the network you use to distribute the signal.

    Most application, if well designed, will limit the number mainly because of d).
    a) and c) can be looked up in the datasheets of the relevant products. The output impedance should be low, the input impedance should be high, hence the problem, assuming b) has been properly catered for, will fall back to d).

    Sorry that I couldn't be more specific. Maybe you can look up a) and c) and elaborate somewhat on your intended application.
