Product Description
Manufacturer Part Number: DS270-PR
The Dayton Audio Passive Radiators are excellent general-purpose passives suitable for replacement or for new construction.
Overview:
Dayton Audio DS270-PR 10" 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: 21.9 Hz Vas: 3.73 cu. ft. Qms: 3.98 Cms: 0.60 mm/N Rms: 3.1 kg/ Mms: 88.4 g Sd: 353 sq. cm. Xmax: 11 mm Dimensions: Overall diameter: 10.63", Cutout diameter: 8.94", Depth: 2.81".
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 10" woofer/subwoofer that has 10mm of X-max would require 2-10" passive radiators with 10mm 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 purchased these to replace some old worn out radiators in my Realistic Optimus T110 speakers. I am not sure how well they would work with the original woofers. I replaced mine with the dayton RS225 woofers. The radiators operate without any noise. I added weight to mine and put a little gorilla glue to hold everything in place. They have held up so far to extreme low frequency with high power. I almost purchased the step up from dayton, but glad I went with these. They are very good. As with anything be sure to drill small holes in your cabinets before running screws in! Very happy with the purchase. (check out the dayton woofers on their website. awesome products!)
