80 Watt 23 kHz, different housings available
At first sight, this transducer seems not very different form other ones in our range. Power of 80 Watt is not exceptionally high, and response frequency of 23kHz is not exceptionally low. However, the trick is in the size. The other low response frequency transducers in our range, have a foot-diameter of 78 mm. While this model has a foot-diameter of only 45 mm. That makes this model especially apt for installation on box-coolers.
