Can anyone comment on the comparison of the Callisto and the Europa? Also, are both speakers using the same drivers?

Roy can answer your questions on the drivers. I hope to be doing a side-by-side comparison of Callistos and Europas later this month. I will post a detailed comparison and review when I do.

It looks to me like both the callisto and europa use the same LF driver (from Aurasound). To get the higher sensitivity I suspect that the Callisto (and Europa max) use a more expensive Morel tweeter, as the more expensive MDT-31 and MDT-33 are more sensitive and have better low frequency response, but are similar in other respects to the tweeter used in the Europa (which might be a MDT-30 ... I don't know, I haven't remove it).

I really like my europas, but I have to say that the Callistos, on paper, don't look like they justify the additional cost. That said, I've never heard them, and I'm sure a big portion of the cost is recovering the engineering and design time, rather than the increased driver/crossover cost.
