I’d start with a single sub assuming that the subs used if two are not as good or well matched to the system. Getting the right sub to match is paramount. Best to start with one. That’s all you need if listening from a single sweet spot. Then, if needed to balance out other parts of the room, add more later. I’d stick to a single sub model that matches well though different models might work as long as all match similarly well but I would get one right first then add more of same if needed.
One question I have is how are people connecting multiple subs to their two channel systems not necessarily designed to output to multiple subwoofers out of the box in a manner that maintains proper load?
