Accuton P173 Passive Radiator with Aluminum Cone

Link to Spec Sheet PDF

The P173 is a high-tech 6.5" passive radiator with aluminum dome. Extra mass can easily be added to tune the resonance frequency. A simple screw mount provides fixing of stainless steel discs (not included) in the desired quantity. The values of Vas and Cms allow for extensive tuning and various box sizes. The stated resonance frequency of the passive radiator is taken at 3mm excursion to give a realistic value. It can be calculated by the following equations:

Fres= sqrt[1/(Cms corr.) x Mms x 4 pi^2)] with Cms corr.= 1/[(1/Cms) + 1/((Vb/Vas) x Cms)]

  • 173mm flange diameter
  • 145.6mm cutout diameter
  • 6.35mm flange thickness
  • Fs 41Hz
  • Vas 24 liters
  • Sd 130 cm2
  • Mms 15g
  • Cms 1.01 mm/N
  • X-max 10mm

Design Suggestion:

If used with the C173-6-191 or C173-6-191E, try a 0.5 to 0.7 cubic foot box and add 15 grams of weight to the passive radiator.
