The Mini Maggies look promising, it's a shame that the sensitivity remains so low (86 dB).
Magnepan has some interesting comments on their web page regarding the minis:
"We often are asked if the Mini Maggie System can be used in lieu of one of our larger models. There is a good reason why line-source drivers are big. We suggest that you view the Mini Maggie System as a solution to a installation dilemma---especially well-suited for small rooms.
Because a woofer/satellite system is uncharted territory for Magnepan, we urge caution. Look at the manual for installation instructions as a woofer/satellite system. The setup involves a lot of unknowns, so, we suggest that customers negotiate an agreement with their dealer. If it turns out that your particular installation or room acoustics are not conducive to a Mini Maggie System, there should be some remedy for the customer. "Buyer's remorse" is bad for business."
It definitely seems like they stand before their full size products before the mini.
