Product Details

Dayton Audio DMA90-PR 3-1/2" DMA Series Passive Radiator

The DMA90-PR 3-1/2" 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 DMA90-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 DMA90-PR introduces a new range of possibilities.

 

Specifications: • Fs: 38.0 Hz • Vas: 0.082 ft³ (2.32 liters) • Qms: 5.01 • Cms: 1.10 mm/N • Mms: 15.9 g • Rms: 0.76 kg/s • Sd: 38.5 cm² • Xmech: 8 mm • Dimensions: Overall diameter: 3.54" x 3.54", Cutout diameter: 3.29", Depth: 1.85".

 

Tip: As a general rule, the passive radiator(s) should have at least double the displacement of air (Vd) as the active woofer(s)/subwoofer(s) in the system.
To calculate Vd: Sd x Xmax = Vd
