    If my speakers are advertised saying their frequency response is 36-22khz should i be looking to set my subs high cut at around the 40hz?
    Thanks to all that help.

    In a word, yes. Around 40/45hz will do.

    NO! If your sub is is connected via line level (RCA/phono) and you use your setup for 5.1 surround sound (i.e. incl. LFE) you must set it to maximum or at least >120Hz as else the LFE is cut.
    The receiver will decide where to cut for those speakers set to SMALL - some allow to adjust the frequency while others have it fixed (e.g. at 90Hz), depending on make and model.

    I presume he meant high-level cutoff by "high cut". =\

    Still, the x-over of the subwoofer should be set to the maximum or greater than 120Hz.

    Should have asked what the speaker settings were!:rolleyes: Reiner´s right, if all speakers are set to small, all bass to sub then the crossover on the sub should be set to MAX.

    If the fronts are set to Large and bass set to both (sub & mains) then you would set the crossover on the sub to around the lowest frequency your speakers go down to i.e 40/45hz. I wouldn´t set the crossover higher as you´ll end up with bass-doubling.

    I second that though one should note that some receivers won't redirect the LFE to the fronts if the BOTH option is choosen and thus you loose out on the LFE again when limiting the sub to anything lower than 120Hz - in which case the combination of LARGE and BOTH would probably be preferred while the sub remains at MAX.
