    Greeting all. I am a complete novice at all this HT stuff, but have been reading the forum for a while.

    I will admit that much of what is said is still going way over my head.

    I have a simple Pioneer HT system and I do enjoy it but am confused regarding how to calibrate my subwoofer. I have 3 choices for the LFE setting (off, 0 and -10). The -10 says that it will reduce distortion, but I haven't heard any. I also can't really detect any difference between the 0 and -10 settings.

    I watched JP III last night and was flipping back and forth on the LFE settings and really didn't notice any difference.

    Granted, its a low end system and I don't have a trained ear, but which setting should it be on for the best possible bass sound?

    Please provide me with an answer is simple layman's terms. I have searched out some former threads on the subject and regretably, I don't understand much of what is being said.

    Other than that I do enjoy my system and don't see myself upgrading in the near future.

    Thanks

    Does your system also have a SUB level adjustment? If so, then that's the one to adjust your calibration. If not, the leave it on 0.

    Are you using a SPL meter and the internal test tones?

    Joseph,

    Sub-woofer settings can be very confusing, beacuse you must

    make adjustments both on the sub and in the receiver's set-up

    menu. Its usually best to set the sub switch to 'on',

    the volume to 1/2, and do the rest of the adjustments with

    the receiver menu.

    I would highly reccomend you to purchase, study, and use

    two additional HT items:

    1) Avia guide to home theater DVD. (45 USD)

    2) Radio Shack Sound Pressure Level Meter (40 USD)

    The Avia guide will quickly make you very competent with

    HT and the test tones included are great. The meter will allow

    you to calibrate your system to the Avia test tones.

    Thanks for the info guys.
    Bruce, to answer your question. No it doesn't have a sub level adjustment that I am aware of. I am also not using a SPL meter, since I didn't even know what one was...lol
    However, the unit does produce its own test tones and recommends setting each speakers volume so that they all sound the same. I also had to individually set the distance of each speaker to my sitting point.
    Jim, thanks for the tips. I will look into them. [​IMG]

    Could you post the model number of your receiver? It's possible some here has one or has had one in the past.
    I keep forgetting that not everyone knows about the Radio Shack SPL meter. It's kind of ubiquitous around here. [​IMG]

    OOPS!
    I messed up the Avia reference.
    Try this:
    Avia DVD
    Sorry,
