[QUOTE="Bennett Prescott, post: 92388, member: 4"] Re: Cardioid Subs in a Smaller venue. It should have the same effect as just moving them farther apart would, it's not a tremendous effect. The whole goal here is to have the two woofers interact, a meaningful boundary would detract from that and make the pattern less, not more, regular. There is always going to be a frequency at which there is maximum forward addition, and below which there is a (1st order?) rolloff, and that frequency is set by driver spacing. With a reasonable LPF it is totally possible to get subs close enough that it appears they are just canceling, however if you would remove that low pass you would see the same behavior you're trying to get just pushed an octave or two higher than you'd like it to be.
