Battery powered equipment for installations

Hi All

I am looking for pointers to battery powered and blue tooth equipment.

I want to use small speakers on and in resonant objects for a museum project.

And I’d also like to make a performance in a space with no mains available.

Mixers and small (small as cheaply possible!) Bluetooth speakers.

And i am very interested if there is experience here on running either of these.

Thanks all!

Exciter speakers can be battery powered if you find the right amp for them. If you use a small exciter, any battery-powered amp designed for small speakers should work in theory. But better ask somebody who knows more about it than I do.

So maybe check this thread: Transducers / Exciter Speaker

EDIT: this was teh TWSU kit: It’s a really basic amp they have there.
