BX65S BS Acoustic Speaker

2.7" wideband invisible speaker. It is designed for mounting on a flat surface. Unlike conventional speakers that create sound waves using a cone, this speaker creates sound waves using vibrations of flat panels on which it is mounted. You can use it to make a speaker from any flat surface, such as ceiling panels, glass surfaces, plastic plates, etc. For example, you can create a speaker from a picture hung on the wall. A very suitable sound box is 2mm thick glass. It will also make a tabletop or a cabinet or cupboard door sound.
