This 30W 8Ω exciter (or vibrator speaker) produces sound waves vibrating the surface on which it is positioned. Thus each surface and each material will react in a different way to propagate these sound waves. The small size of this speaker allows it to be used in confined areas, in which a conventional speaker could not fit. This speaker connects to your amplifier system in a classic way and can also be used to increase the sense of immersion in a home theater audio system.
