just to expand on this a bit.
jbl uses the 2242h driver (more or less) in its cost-no-object home theater systems. it is an efficient, pro audio style, driver that is put in an enclosure tuned to 25hz. for most folks, this amounts to an absolute BLASTING of bass. however, to others, since it rolls off around 20 hz, it doesn't pick up the subharmonics.
ricci has build using the xxx 18" in a huge ported enclosure with a very low tune, ~15hz if i recall. subjectively, he remarks the thing sounds like a jackhammer pounding on the foundation of his home while playing deep bass. however, it is not so good for reproducing the upper bass 70-100hz that is associated with the "punch" in lots of rock music.
sorry if i confused things in an attempt to clarify.

I've not heard the 15" version, but I would expect a single 15" to have the edge in value, and dual 12s to have the edge in SQ. If you go with duals, you have a couple of extra benefits you can take advantage of... you can place them in different locations to help even out room response, or you can place them in the same box and reverse mount one driver to reduce 2nd order harmonic distortion (as well as box vibrations if mounted on opposite ends of the enclosure). Two twelves will also have a little more displacement than a single 15". I'm not sure if it's still the case, but Rythmik used to also offer a kit with two 12" drivers and one amp, which helps get the kit price closer to the single 15". That setup is more suitable to two drivers in one enclosure, as there's a servo wire length limit that limits how far the amp can be from the drivers, and you also wouldn't want to "share" one servo control between two enclosures.
Personally, I've been thrilled with the Rythmik kits. Started with two twelves, then doubled that when I needed to build a new box anyway. Four wasn't really necessary, but you can't have too much headroom.

LTD02. Please don't put words in my mouth. I don't believe that I ever said that exactly. You've been pushing this subject a lot lately. I'm going to start a discussion thread on it.
