      Dayton Audio ND140-PR 5-1/4" Aluminum Cone Passive Radiator


      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.


      The ND140-PR 5-1/4" passive radiator includes:

      (1) Passive radiator

      (2) 18.5 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.

      Tested those (for a BoomBox build) with the ND105 (they could handle the drivers but did not get the wanted bass from the setup) AND with TangBand W5-1138SMF (mini earthquake 8inch cube - bass is really powerful but the ND140-PR run out of steam on a half way) ... used WinISD Pro 0.50 Alpha 7 for cabin design.

      I can't rate this product yet, I'm still to test it but what I can say that is that soundimports have been faultless. Helpful advice and quick delivery. Andreas
