I'm not sure he should be doing that. There have been some discussions on AVSforum and diyAudio recently of the Geddes approach to subs, which is (roughly, in my crude paraphrase) to even out bass response using a variety of sub types, placement, and volume-phase adjustments. Essentially, you place the subs and adjust them in whatever way works best.
