5¼" ALUMINIUM CONE PASSIVE RADIATOR

DAYTON AUDIO

The 5-1/4" passive radiator makes it easy to tune small enclosures lower without increasing overall enclosure size. With a one-piece aluminium cone, rubber surround, high excursion capability, and easily adjustable mass, this passive radiator is perfect for building extremely compact speaker systems capable of incredible low frequency output.

Tune small enclosures with Dayton Audio's ND140-PR 5-1/4" passive radiator in speaker designs where a conventional port is not a viable option. This compact passive radiator includes all of the features you expect with larger radiators including high excursion capability, aluminum cone, rubber surround, and adjustable mass. Visually identical to Dayton Audio's popular ND series drivers, the ND140-PR can be used with any small speaker. 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 multi-driver array, sound bar, or portable Bluetooth speaker, the Dayton Audio ND140-PR introduces a new range of possibilities.
