The reason I ask, I'm torn between Rythmik and PSA. In the PSA Power-X line, I'm looking at a minimum of either three XS15s or a XS30 and a XS15 or two. That's right about where my budget runs out of steam.
In this space I ran a single PC12-NSD, at several locations in the room, including right rear corner, front left quarter, and against the rear mid wall, three feet behind the MLPs. The room is a 17x11.5x8 rectangle with a 6x7 aperture on the right wall.
These two subs have rather different response curves and I only have Audyssey MultEQ, so they sound very different in this room. I strongly prefer the response of the XS15s for all content, but I might feel differently if my rooms were much larger.
Ever since I got the XS15s, the sound stage has grown ENORMOUS. This has really brought music to life. I have a two-channel system that's mostly been gathering dust since I started playing music in my main movie setup. It has me tearing through my old collection, discovering new depth in old recordings, sometimes listening to music I don't even like just because it's recorded well and my system does a way better job now, conveying it. The whole experience has been super-rewarding and very surprising.
Anyway I mention all that because I want to acknowledge that to some extent my preference for the new setup is not only about the number of subwoofers. Part of it is that these subs descend much lower than the unit they replaced, and that they don't create such a big hump in the deep bass.
That said, the sound has changed in a couple of ways that I think can only be attributed to the upgrade to two. For example, the XS15s aren't playing significantly louder than the PC12 was, but it feels like there's *more* bass. More frequent tactile bass moments in very familiar content, moments that used to sound subdued and distant.
Also, localization has been dramatically reduced. I keep one near-field so that's kind of a big deal for me. Not only that, but the other XS15 is on the other side of the room, so wherever I am, I'm not that far from a subwoofer. This is a really nice thing, when you hear it.
I have zero desire to add a third or fourth. Not only am I extremely happy with this setup, but it's a small living space already dominated by speakers and electronics. Something I like is that when you're watching the TV, the subs are nearly invisible, so you don't get the visual cue to the origin of the bass; also there's strong symmetry. I'm sure some of the real heads will cringe to hear me say it, but these two points are important to me.
Having owned subs from Energy, Mirage, Hsu, SVS, and PSA, I'm curious about Rythmik, too. [Cue Conan the Barbarian theme] But that...is another story.
