A functioning planar speaker design imbibing various ideas from most non-conventional speaker types. Certain that the driving force also adds bending moment to the driver and hence the title.
Everything built from scratch up. Could have finished in December if it weren't for a dishonest welder. Very promising for a first try. Lots of improvements to come for better HF extension & LF response. Many changes have been made from initial sketch. Might end up as my home system.

Video playing from 600 Hz and up. Noticeable HF roll-off.

How it is made? It is fascinating for me.

just a voice coil running up and down in front of opposite magnet poles. Fleming's left hand rule. I used chart paper for diaphragm but the paper is of high quality and kind of heavy. I will continue this thread with improvements.

Nice photos there.
