Two captivators are equivalent output to one orbit shifter, and give you room smoothing because there are two. If you plan to get two orbit shifters - then the recommendation may change. The orbit shifter is a fantastic sub, but two runs $6.5k. I recently went to a theater of local Kansas city member jedimastergrant who owns a single JTR Orbit Shifter and demoed his new home theater room for a bunch of the KC gang. He has bass in spades, but hot spotting galore. You move from seat to seat in his theater and there is up to 7dB difference (over twice as loud/quiet) with an SPL meter and even more variance than that when you consider frequency response. With my two captivators I have nothing like that seat to seat in my theater room. He definitely needs a smoothing sub - and everyone there told him so. 1 sub pales to 2 unless you have a single listening position you are optimizing for. I've always heard 2 subs pales to four or eight subs, but in my experience with a lot of different rooms and a lot of different subs - 1 to 2 is the biggest positive difference.
