Speaker Podspeakers Visaton K 28 GI round driver 28×28 mm, RMS 0.5 W, PMPO 1 W, 6 g, 1 pc
Podspeakers Visaton K 28 GI round driver is a compact 28×28 mm miniature speaker designed for low-power audio output in small or space-constrained devices. The transducer features a polycarbonate diaphragm and a round plastic basket, delivering clear signal reproduction at an RMS rated power of 0.5 W and a PMPO of 1 W. The unit weighs approximately 6 g and connects via spring contacts on the rear, making it suitable as a replacement part or for integration into prototypes and portable electronics.
The small 28×28 mm footprint and lightweight construction enable installation in tight enclosures where conventional speakers cannot fit. The polycarbonate membrane provides durable and stable sound reproduction for voice and simple audio signals. Spring-contact rear terminals simplify assembly and replacement without the need for soldering, and the round plastic basket ensures consistent mounting in circular cutouts.
Mount the Visaton K 28 GI driver into a circular recess that matches its 28 mm dimension, securing it in the plastic basket so the diaphragm can move freely. Connect the audio source or amplifier outputs to the spring contacts on the rear, observing polarity if required by the system. Drive the speaker with low-power audio signals within the RMS rating (0.5 W) to avoid distortion or damage. Allow adequate ventilation around the driver to prevent heat buildup when used continuously.
For best results in voice and signaling applications, pair the speaker with low-power amplification or drive directly from devices designed for small transducers. Avoid applying power above the rated RMS value and minimize exposure to moisture and harsh mechanical shock to maintain performance and longevity.
