Two subwoofers

Simple question: If you have two subwoofers in the same system properly placed apart and balanced in the room, should they be exactly the same models, amp types and and have matching power outputs? Is it possible if you have two different types that they could be out of sync? For example, if one is a class AB analog amp at one power output and the other a class D digital amp at a higher rated power output, could they be out of sync even slightly?

Yes it is possible but careful volume matching, phasing, and cancellation issues must be addressed. I am currently using five subs(3 different mfr's) in my main HT/music system and believe me, it takes some work and patience to get it "right". I am using a pair of Klipsch RT-10d's in the front corners, a Klipsch RSW-10d next to my recliner, and SVS SB13+ next to my sofa, and also a Revel B15. Different driver sizes(10"-13"-15"), amp powers(500w, 700w, 1000w, 1000w). And yes, my bride is a keeper.
