Dayton Audio DMA80-PR 3" Aluminum Cone Passive Radiator

The Dayton Audio DMA80-PR 3" Aluminium Cone Passive Radiator is a meticulously engineered component designed to elevate the low-frequency performance of your audio system. As a passive emitter, it requires no additional power, making it an efficient and elegant solution for enhancing bass response in compact designs.

This passive radiator is ideally suited for use in small sealed enclosures, where it works in concert with an active driver to extend low-end output and improve overall sound pressure. It is particularly effective in portable speakers, desktop monitors, and custom audio projects where space is at a premium but deep, articulate bass is desired. By replacing a traditional port, it eliminates chuffing and resonance artefacts, delivering cleaner, more controlled low frequencies.

Technical specifications underscore its precision engineering. With a resonance frequency of 34.6 Hz and a maximum linear excursion of 7 mm, it offers substantial cone movement for its size. The aluminium cone ensures rigidity and low distortion, while the polymer frame provides a durable, lightweight chassis. The Qms of 8.91 and Vas of 2.01 litres indicate excellent mechanical behaviour in small volumes. Its 74.4 mm cut-out diameter and four mounting holes simplify integration into existing baffles.

In summary, the DMA80-PR is a high-quality passive radiator that combines robust construction with refined acoustic performance, making it an ideal choice for audiophiles and DIY enthusiasts seeking to optimise bass output in compact loudspeaker systems.
