    There's absolutely no chance of you even beginning to get by without an SPL meter I'm afraid.

    Nimby's sticky at the top of this forum should have all the information you need otherwise. :)

    Let's say I want to select filters and change the setting to suit my room and then I want to store the those setting, that is what I don't Understand. And to be honest with you IF I could find little difference just by using ears then I would defentily go for an SPL but if I cann't find any difference with ears I don't know what help an SPL would offer.

    For a more detailed explanation you'll want to go here:
    www.snapbug.ws/bfd

    Using your ears is one thing for setting channel levels with noise but they simply aren't capable of accurately measuring the volume of individual frequencies. An SPL meter is made for this. With a BFD you're trying to flatten the frequency response of your subwoofer at your listening position. This involves adjusting filters so that the appropriate frequencies are boosted/reduced.

    I'm a bit confused why you bought a BFD having not done any research at all on it? £30 for an SPL meter to setup your system would be a much better investment than £80 on a BFD that you can't use.
