4 Ohm Version

Highly recommended for model boats due to its smaller size and water resistant cone, it can also be used in airplanes, helicopters and tanks - 89dB/1W/1m Sensitivity, but heavier weight - 240 grams (8.5oz)

This German engineered loudspeaker sounds great, yet is very shallow and weighs 240grams (8.5oz). This fine loudspeaker can handle 20 Watts continuous, 30 Watts peak.

This 4 Ohm speaker can be used with our ShockWave series sound modules with no more than a 4S LiPo battery. If you wire two of these in series, the sound module can be powered on its maximum battery voltage of a 6S LiPo for maximum sound output.
