Overview

Dayton Audio SS12-PR 12" Signature Series Passive Radiator

Dayton Audio SS12-PR 12" Signature Series Passive Radiator

The Dayton Audio SS12-PR 12" Signature Series Passive Radiator is the perfect solution for extending low-frequency response in compact subwoofer enclosures. By replacing a traditional port, this passive radiator makes it possible to achieve deep bass without turbulence, port noise, or oversized cabinet designs. When paired with the SS12-22, the SS12-PR creates a system capable of powerful, articulate bass extension in a space-efficient format.

Signature Series Styling and Construction

To visually and mechanically match the Signature Series subwoofers, the SS12-PR uses the same rigid cast aluminum frame, thick anodized aluminum cone, and high-roll rubber surround. From the front, it is indistinguishable from the SS12-22, giving finished systems a seamless and professional look. Its durable suspension and rigid cone allow for the high excursion necessary to complement powerful subwoofers while maintaining low distortion.

Innovative Sandwich Mass Structure

At the core of the SS12-PR is Dayton Audio’s Sandwich Mass Structure (SMS) system. This design places all added tuning mass between the spider and the surround, keeping it perfectly centered and stable during long excursion operation. A threaded bolt with both a wing nut and a nylock nut makes adjustments secure and easy, while the included set of five 116 g weights provides plenty of flexibility for precise tuning.

Achieve Effortless Deep Bass — the Perfect Partner for the SS12-22

With its rugged construction, refined design, and innovative tuning system, the Dayton Audio SS12-PR is the ideal match for the SS12-22 subwoofer. By making it simple to unlock extended bass response from compact enclosures, the SS12-PR delivers the performance and flexibility that today’s home theater, hi-fi, and car audio systems demand.

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. To calculate Vd=Xmax ∗ Sd
