RE: Thanks too.

I am not really a speaker guy but that won't stop me from musing...
Assuming you can get the same frequency response from the closed-loop system as applying equalization to the open-loop system the next thing has to be excursion and distortion. For the same acoustic output and the same cone area the excursions must be the same/very similar. A closed-loop system should have an advantage in overcoming deficiencies in the driver but I don't know how well this one works to reduce distortion. It is monitoring velocity, not displacement and the point of maximum excursion where the cone changes direction produces little/no velocity feedback. So I don't know if it is effective. Someone wiser than me pointed out on this forum years ago that the Rythmik feedback system was developed for sealed subs to overcome the air loading inside the box, which is not a problem for open baffles.

Maybe, then, if you can get the frequency response you want and the excursion you want the rest doesn't matter?
