‘SFX Gel Audio’ is a hydro-gel coupling product that can be used on…. well, almost anything. I kid you not…

Ok, sometimes I kid, but this is what SFX Technologies say:

“The design-patented SFX Gel Audio transducer produces high-quality sound when placed against a wide range of materials including glass, plastics, metals, wood, composites and even some fibrous materials.

When the SFX GA transducer is placed against a surface, that material becomes a loudspeaker.”

I for one hope the concept will stick…
