    What is the sub setting on your amp? My crossover is set to max on the sub. The amp dictates what frequency is sent to it.

    i've set it to full on the sub. the amp offers 50, 80, 100, 150, 200hz cross over, but which should i choose? it says 80hz for THX speakers.
    Tha amp is an ax3 and the speakers are kef 1005s

    80 sounds like a good setting to me. With all speakers set to small.

    In that instance I would choose 150Hz.

    What's the point in setting an 80Hz crossover if his speakers only go down to 120Hz. If there's really no usable output below this, then it really needs to be set at 150 (assuming the sub will go up to 150Hz).

    The downside is that you may be able to hear that the bass is coming from the sub, in which case, you may be better off going for 100Hz and putting up with a 'hole' in the frequency range.

    Try 'em both. Keep whatever sounds best.

    Bloody hell, things move fast round here. My reply became irrelevant in the space of 3 minutes.

    I suppose it was aimed at you, but not in a way that you should have taken offence at.

    Seeing as you have though, I wasn't expecting you to check his speaker specs, just to have read the original post.

    :rolleyes:

    A phase control is designed to compensate for tthe fact that the bass is not coming from the speakers, but from another location in the room (your sub). Depending on the subs position in the room, it may sound better with the phase set to 0 or to 180.

    As suggested, use whichever sounds best, and if you can't tell the difference, don't worry about it.

    Take offence, never mate. ;) Not for something like that.
    As for not paying attention/miss reading the original question, guilty as charged.:blush:

    Gave the right answer in the end though.;)
