Hi all. I was thinking about the above idea the other night. Has anyone there tried putting a shaker transducer right in the centre of a board so that it would be a direct radiator rather than shaking you or the furniture directly? I suppose you would have to be careful of the vibration mode of the board because it would be certain to suffer "board breakup" 😉 as it got ripples in it as it approached it's flexing resonance. Would it be a goer? Would one with a suitable flex-plate attached be suitable as a sort of compression driver for a horn loaded system? Sorry if these are hoplessly ignorant questions.

I'm pretty new to the Home Audio side of this, but I have worked with Bass Shakers before, and I think with a suitable flex plate you could probably use it as you've mentioned. Though I don't know how good or bad the resulting sound would be. I don't know about the idea with the board though... that's just a little abstract for me to picture, and when I do picture it, all I see is a wobbling board... Either way, I've found experimentation to be the key.

They were sensitive but prone to peaky/resonant response.
Also, is your description that of the principal of the modern NHT flat panel transducers ?.

Remember very old horn speakers that connected to crystal sets that had a telephone earpiece as the transducer - the ones with a coil and polepices arrangement with a stiff steel disk as the moving component ?.

i use bass shakers, for HT on my couch, and i couldnt imagine them producting much usable output for a horn. they do transfer quite a bit of energy though.
interesting project, keep us informed!

What about installing bass shakers directly behind walls?
shaking your walls could turn out to be fun.. 🙂

i live in an apartment. i am moving in a couple weeks though, to a house. hopefully my roommate (owner) would let me mount them to the floor beams below (that part of the basement is unfinished)
they are really cool. they add a lot to music and HT.
