    I am trying to setup my system,
    Just replaced my Technics SA-DA10 with HK AVR-430 , I tried AVIA but I wasn't able to get the test signal just to LFE.
    What do you use to set it up?
    Should I get something else like DVE ?

    Thanks in advance

    In Avia there is a Subwoofer Sweep that will effectively sweep from 100hz down to 20hz that is LFE only.
    In calibration it is usually the idea of getting your subwoofer levels to match your mains so this is why Avia has them mixed together.
    If your just trying to Parametric Equalize your subwoofer then you can use a CD called Autosound 2000 CD 101 which has a few subwoofer only sweeps and every single frequency from 20 to 100 in 1 step increments.

    Ok let me try to explain my problem,
    maybe someone with HK may have idea what is going wrong.
    When I try to setup the sub, the fronts try to pass low F. too. I don't know why, even I have set in HK that the sub is just LFE not LFE +L/R but still the same problem.
    I remember someone else had this problme before but I couldn't find the post

    Do you have your main speakers set to Small in your receiver? If they are set to Large, they will pass bass.

    yes, I set them to Large, but is that bad, here is the spec, on my fronts
    Recommended Power Amplifier Range: 15 - 175 watts
    SUBWOOFER - 100W
    Frequency Range: 32 - 20kHz
    Sensitivity: 92dB (2.83 volts/1 meter)
    Nominal Impedance: 8 ohms
    Woofer: 8"
    Mid-Bass Driver: 6.5"
    Tweeter: 1"
    Crossover Frequencies: 110Hz, 2.7kHz

    Should I set them to small during the setup, and switch them to large after I finish with AVIA, what would you recomend?

    Thanks

    If you set your receiver to Large speakers bass will be sent to your woofers in your speakers. Its not necessarily a bad thing, but since you have a subwoofer you may want to set your speakers to small (even though they may physically be large) so that bass will only be sent to your subwoofer.
    I would keep them at one setting either small or large depending upon how you like the sound when you calibrate. Changing your settings after you calibrate is never a good idea. Personally, I keep my speakers set to small even though I have large speakers, its so that my subwoofers handle all of the bass that is being fed to them below the crossover of 80hz in my 5.2 setup.
    Also check your crossover setting for your subwoofer. THX recommends crossover set to 80hz which may not be the best setting for every setup out there, however it is a good place to start.
    Listen and see what works the best for you, your let your ears decide.

    Personally, I'd still set them to small and experiment with whether a 60 Hz. or 80 Hz. crossover sounded better.

    Oops, Glenn was responding just as I was typing. Sorry, for repeating some of what he said.
