Question regarding subwoofers


I have an RHLabs SB-1 that’s served me pretty well for many years and use with it with my Acoustat 1+1s. (Had it refoamed a couple years back.) As well as the 1+1s image, I’ve always been slightly annoyed by having a single subwoofer between the panels. When playing something with a large sonic image like orchestral music the setup works fine. However when playing something more intimate like Jazz it’s easy to "see" where the lower frequencies are coming from: The middle. As my listening has gotten more refined it’s getting to be less acceptable to me. So I’m looking possibly at a pair of smaller, powered subwoofers. Why powered? Simple: If I do this, I’d rather the ARC VS-110 just power the panels. So, my questions:

1) The SB-1 has a single 10 or 12" driver. I’ve seen subs anywhere from 8" to huge. What folks experiences been with a pair of 8-10" powered subwoofers? Too much? Not enough?
2) Did a pair of subs affect imaging much? IOW, could you discern enough left/right to make it worthwhile?
3) How tough was it to balance them?
4) Do I run another set of interconnects from my SP11? Or do I get a set of Y adapters to feed both subs and amp?

Let me close by saying that like with most things audio there’s going to be a lot of "it depends". I get it. But I’d still like to hear of folks’ experiences as I do see a lot of systems with subs.

As always, thank you much for your time and comments!

@musicfan2349 if you can easily locate your sub in your room then it is not integrated well, one way or another. Either crossed over too high, gain too high, or some combination of placement and the others. Some rooms are very tough to nail, and that is where the multiple sub concept works. It is possible to integrate a single sub and make it “disappear”, but that requires speakers that dig down pretty low and a cooperative room/setup. Overall, it is much easier to get 2+ subs to integrate as a whole. But one can be done...
