Overview

Dayton Audio DMA58-PR 2" DMA Series Passive Radiator

The DMA58-PR 2" passive radiator from Dayton Audio is the perfect option for achieving low tuning frequencies from the smallest enclosure designs. This incredibly small passive radiator has all the features you would expect lager units including adjustable mass, aluminum cone, and rubber surround. Visually identical to Dayton Audio's full-range DMA series drivers, the DMA58-PR can also be used with any small driver that requires a low tuning frequency. The threaded rod and included wing nut on the back of the cone makes it easy to add mass to tune the radiator as needed for your projects. Whether you are building a smart speaker, sound bar, or portable Bluetooth speaker, the Dayton Audio DMA58-PR introduces a new range of possibilities.

To calculate Vd: Sd x Xmax = Vd
