Key Features:
Dayton Audio DS215-PR 8" Designer Series Passive Radiator
The Dayton Audio Passive Radiators are excellent general-purpose passives suitable for replacement or for new construction. A built-in mass disc offers a good starting point for most designs, and a convenient M5 threaded hole (screw included) allows different types of weights to be added if desired. Cosmetically and mechanically, the passives match the Shielded DVC line of subwoofers, with a poly coated paper cone and medium-roll rubber surround for clean excursion and long life. The possibilities with these passives are endless, from floor standing two-ways to small active/passive subwoofer systems.
Specifications: Fs: 23.3 Hz Vas: 1.52 cu. ft. Qms: 7.34 Cms: 0.68 mm/N Rms: 1.4 kg/s Mms: 68.8 g Sd: 211.2 sq. cm. Xmax: 11 mm Dimensions: Overall diameter: 8.50", Cutout diameter: 7.125", Depth: 2.28".
Note: Adding mass to the passive radiator will decrease Fs and increase Qms.
Tip: As a general rule the passive radiator(s) should be able to move double the volume of air as the active woofer(s)/subwoofer(s) in the system. For example: A passive radiator system for a 8" woofer/subwoofer that has 9mm of X-max would require 2-8" passive radiators with 9mm of X-max. For single passive radiator systems, it is common to use a passive that is larger than the active woofer(s)/subwoofer(s).

I used these as passive radiators for a home built project. They come with a mounting machine screw so you can attach weights to the cone to dial your setup in more precisely, and the construction seems good.I used these passive radiators to a different model of subwoofer than these were designed to be used with, but the sound quality is still good, so unless you are very picky, these can be used with woofers other than Dayton.Good construction, good price, clean look...good enough for me to give them 5 stars.
