Lol, I had the same thought after I bought a couple of X-mini I's, but first of all I can vouch for that they're working, and your has a better sound quality than mine. Also Wildflower used a single capsule speaker as well.
Shannon addressed in one of the threads (something about a guy who had one faulty satellite or earbud, while he wanted to continue using the subliminals) that you do need both channels for maximum effect, but what I got from that, that it doesn't matter if it's coming from a single source, as long as both channels run through it.
Hehe, too bad the dual X-mini's were all 18 kHz :p
