I have a Fostex PS-3.1 monitor system which consists of 2 satellite speakers and a sub-woofer. The sub is self-powered and also provide power to the satellites.
My question is, where should I place the sub? I have had it off to the side, but it messes with the direction of the bass. (Eventhough the Fostex manual says bass is non-directional, I swear I can hear what direction it's coming from!)

Thanks.
