Yeah, I saw those on ebay, but they are a different model. Mine are simply XP-15's and have a different configuration. The covers are glued on, so I'm not sure what's behind them, although there appear to be at least four speakers in each panel. Here's a photo of the model I have:
Sorry to be such a dummy, but I'm not very good with speakers. Thanks!
I know it's only rock & roll, but I like it.
