If the motor was made using a longer conductor to span the distance of a larger membrane, then voice coil resistance would increase and mass would also increase. Both things tend to reduce sensitivity and decrease mass cutoff.

Individual elements gives you wiring options. If all are wired in
parallel, you get max sensitivity, must make sure you have a good
amp to drive the lower impedance.

I was assuming one large membrane and frame with multiple voice coil/magnet assemblies wich could be wired in parallel/series as with a collection of individual drivers.

I really have my doubts about a ribbon that long if it's a "pure" ribbon only suspended at the ends. I suppose a planar magnetic (ala' BG) would be possible in that length; however, it still will have the problems that Jim noted.

A few months back I was sent a prototype of a pure ribbon that was about 24" long. While it sounded pretty good mechanically it was quite floppy. The weight from the magnet structure was about 40 lbs. and it pulled the reversible bit right out of my screwdriver! Not too practical for stacking them to form an array.
