    Default XO freq setting

    So I just moved and am setting up my 5.1 system again and I cant remember how I had everything set up. I know this will be a stupid question, but could those in the know on here tell me how my speakers should be setup for the following:

    Size: small or large
    Crossover frequency: I think I had it at 120Hz but for my LSi25's what would people recommend I have it set at?

    I know these are total newbie questions but its been so long since I moved I forgot how all of this works. For some reason, my reciever went back to all the default settings so i dont remember what everything was set at before. Thanks for any help you can give!

    On my mains, does it matter that the 25's have a powered subwoofer? Should I still set them to small?

    My recommendation:



    ① ⇓-Preference-⇓
    ◊ Main speakers - SMALL - crossover to 60 Hz,
    ◊ Center - SMALL - crossover to 60 Hz,
    ◊ Surround - SMALL - crossover to 60 Hz,
    ◊ Subwoofer - crossover to 60 Hz,
    ◊ LFE (Low Frequency Effects) channel - crossover to 120Hz.


    ◊ Main speakers - SMALL - crossover to 80 Hz,
    ◊ Center - SMALL - crossover to 80 Hz,
    ◊ Surround - SMALL - crossover to 80 Hz,
    ◊ Subwoofer - crossover to 80 Hz,
    ◊ LFE (Low Frequency Effects) channel - crossover to 80Hz.


    ◊ Main speakers - SMALL - crossover to 80 Hz,
    ◊ Center - SMALL - crossover to 100 Hz,
    ◊ Surround - SMALL - crossover to 80 Hz,
    ◊ Subwoofer - crossover to 80 Hz,
    ◊ LFE (Low Frequency Effects) channel - crossover to 120Hz.

    ④ ⇓-Preference-⇓

    ◊ Main speakers - LARGE,
    ◊ Center - SMALL - crossover to 60 Hz,
    ◊ Surround - SMALL - crossover to 60 Hz,
    ◊ Subwoofer - crossover to 60 Hz,

    LSi are speakers at 4 ohms. Check processor.

    So I should set my mains to "small" even though the Lsi25's have a powered subwoofer in each speaker? I assume the subs in each are separate components even they're housed in the speaker rather than being a seperate sub? Just want to be sure before I make the switch!

    Honestly i've never used powered speakers so someone can answer that better than I can.
