Those lamellas look pretty hard to drive - and I imagine they have to be heavily damped somehow to prevent internal vibrations (a lamella is like a guitar string just much thicker but anything long and narrow and flexible is sure to vibrate) - so be very careful - I am not sure there is a free lunch here as surely MBL would have thought of this if it were possible.
I'd hazard a guess that the limitation is in the output of the midrange of the lamellas and not the bass woofers. This is of course speculation on my part so you would probably be best to contact MBL.
