        Product description

        The Dayton Audio ND90-PR 3-1/2" passive radiator makes it easy to tune small enclosures lower without increasing overall enclosure size. With a one-piece aluminum 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.

         

        Highlights

        • Rigid black anodized aluminum alloy cone
        • High excursion capability: 18 mm peak to peak
        • Same "family look" as ND Series woofers
        • Adjustable mass for a vast range of tuning frequencies

        Dayton Audio ND90-PR 3-1/2" Aluminum Cone Passive Radiator

         

        Tune small enclosures with Dayton Audio's ND90-PR 3-1/2" 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 ND90-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 ND90-PR introduces a new range of possibilities.

         

        The ND90-PR 3-1/2" passive radiator includes:

        (1) Passive radiator

        (2) 7.3 gram disk weights

        (1) Wing nut

         

        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.

        Very good for small speakers. I tried several box volumes and passive radiators waight but i can’t able to reproduce deep bass below 80/90 hz. Good sound but needs a sub reinforcement for my tastes.
