Re: Stationary voicecoil?
The mms of a moving magnet versus moving coil would likely end up with an unusably low sensitivity,even with neodymium magnets. A small enough magnet to keep the mms reasonable would have too low a bl product as a result. 5 inch excursion is the domain of servodrivers, not dynamic drivers. If that's your goal a servodriver is the way to do it.
