Everything about them says 'isobaric', so while the response to size ratio will be good, the output won't be. Watts don't matter, decibels do. The manufacturer won't reveal any details about them, while their lead spokesman seems to be seriously lacking in the knowledge department. I doubt he can spell 'isobaric', let alone know what it means.

Isobaric with mixed sized drivers? How well is that likely to work?
