probably an experimental driver to test how cone resonances in the midbass sound

how about enabling it?

Looks like some variant of the infamous "elephant ear's" speaker. The ones I have seen so far had a black cone and a square frame. The cone had almost the same shape but the remaining triangular space on the frame was used as a reflex hole.

To All,

These are production drivers used in Yamaha Elecrtonic Organs.

I recently repaired an amplifier that drove one of these.

If it's for an organ, then it should go very looooooow.

Thanks.
