Anyone experimented with flat panel actuator driven speakers. Saw YouTube video tech information "world's best speaker? Integer by the concept and of course cheap me price. Cheap $20 40 watt actuators or excitors are adhered to poly styrene ceiling panels at 2/5 3/5 ratio o counter resonance peaks. Sound like a very cheap fun audio challenge to try. Other material like cardboard aluminum balsa wood you name it are fair game. Challenge some of you to try different media. Can't go wrong with $40 both actuators and practically throw out material to make. Give me some feed back on any results or ideas. I will order a couple to just have fun with. Michael

i guess you've not come across this thread https://www.diyaudio.com/community/threads/a-study-of-dmls-as-a-full-range-speaker.272576/
I had both the 8” polyplanar and heard the bigger rectangular panel. They suck. They do make noise.

Hey Dave, post don't go through to XRK971 just thanked them for all the nice graphs and informative input into mdesigning DML flat panel transducers. Will try to look up an expert in this subject . CLS is his initials You know how to find information he has out? Let me know. Michael
DML panels are a significant “development” of driven panels.
Unlike the polyplanars that are just a dynamic driver with a crappy cone, DMLs use statistically equivalent resonaces in the panel to genergate sound.
Very different physics.
DML panels tend to really struggle at the bottom, so initial uses in the closing of the inventor, have concentrated on midranges.

Better bass might be achieved through longer rectangular shapes that would produce the area needed for longer wave lengths Size shouldn't be an issue for most since on the wall usually. Great midrange is more important to most so let's work on bass. Upper end frequency is another issue. Maybe using tweeter specific drivers and separate panels will help. I have a few dome tweeters with damaged domes I am experiment with know will let you know progress Thanks Michael
Glued tube onto old tweeter voice coil and attaching to different panel material trying on doped piece of fabric coated with paint on poly urethane.let you know results after changing size. Michael
