Medium Surface Transducer with Wires - 4 Ohm 3 Watt

A medium surface transducer that turns any flat surface — tables, walls, panels — into a speaker. Unlike traditional cone speakers, a voice coil wrapped around a metal rod causes vibration that transfers directly to the surface it's pressed against, producing surprisingly clear sound from the surface itself.

The transducer has a heavy body so it can simply be placed top-down on a surface. It operates at 4 Ω impedance and 3 W, making it compatible with common Class D audio amplifier breakouts. Pre-soldered wires are included for easy connection.
