    The performance of a sub, more than with speakers, is dependent on the room it is in. This is because they deliver deeper bass than most speakers. Bass, at these frequencies, has wavelengths that relate to the measurements of the room you are in.

    Did you do those experiments at school where you vibrated water and created patterns? If you did, you're going to 1. wish you'd paid attention and 2. realise why the stuff they taught was actually useful in the real world.;)

    Anyway, because of the way these waves reflect off the walls/floor/ceiling, means the waves can interfere with each other. Sometimes this results in positive interference (a strong boomy frequency) and sometimes it results in destructive interference (where'd the bass go?).

    Now, this may sound odd but the bass you are experiencing can only be experienced where you are sitting. The person next to you may be experiencing entirely different bass. This is because these effects are localised which means you can move them. Or move the sub, or move yourself. Or move everything. Same difference.

    This is what is being talked about when people talk about room tuning. They're trying to find the point in the room for the sub and yourself, which produces the least bass anomolies at the listening position.

    Welcome to one of the most annoying and potentially most rewarding journeys in home audio.:devil:

    I'd start by starting again. You need to combine the basic subwoofer setup tips in the FAQs with some basic system setup - distances, levels, etc. Get a baseline to start experimenting from and even if you don't intend leaving it there, don't be scared to pull the sub well out into the room.

    I'd be looking at the crossover setting on the amp too.
    My guess is, it's set too low.
    I'd start with 100 hz, depending on the speakers obviously.
    Make sure the sub crossover is set to max
    I'd also turn off the notch filter.

    By reading the manual.
    That's not meant to be sarky, but it really is a must.

    It should be in the sound menu settings.

    oh also i just read the faq thing on the sub forum. one of the guides told me to set all my speakers to small so that the bass is re-routed to the sub. i think this was part of my problem as some of the bass was coming out of my front speakers.
