The thing that drew me to the Gemini was that I could be playing a track through one woofer while playing through the other, but if the Xitone has bluetooth, I just think that's icing on the cake. I probably wouldn't have as much utility for a single mono wedge having bluetooth, but who knows? The more I scrutinized the Gemini, though, the more it seemed like a bad option for me; I was also liking the idea of "amp in the room", but if I'm ultimately going to be playing on a PA, that's probably not something that matters much, and I can't just try this kind of gear, so informed decisions are important. The instances wherein I'd be playing backing tracks would mostly be at home, so I see no reason my studio monitors wouldn't cut it for that, but I'm not at all savvy with this stuff.
I pulled the trigger on the Xitone because the sound foremost seems to be what I'm after, and it doesn't hurt that it's so compact vs the Gemini. I wasn't even digging into the features so much, haha, I've just looked around at a lot of demos and opinions.
