Dayton Audio SS18-PR 18" Signature Series Passive RadiatorThe Dayton Audio SS18-PR 18" Signature Series Passive Radiator is engineered for subwoofer systems where only the deepest, most powerful bass will do. When paired with the SS18-22, it makes it possible to achieve extreme low-frequency extension and earth-shaking output without the turbulence, noise, or oversized cabinet requirements of vented designs. Perfect for dedicated home theater rooms and ultra-high-output music systems, the SS18-PR delivers the tuning flexibility and rugged performance required for the most demanding installations.
Signature Series Styling and ConstructionBuilt to visually and mechanically match the SS18-22, the SS18-PR uses a heavy-duty cast aluminum frame, thick anodized aluminum cone, and high-roll rubber surround. From the front, it looks identical to the powered driver, giving large systems a clean, unified appearance. Its suspension and cone are designed to handle the extreme excursion necessary to complement today’s most powerful subwoofers while maintaining accurate, low-distortion motion.
Innovative Sandwich Mass StructureThe SS18-PR incorporates Dayton Audio’s Sandwich Mass Structure (SMS) tuning system, which places all added mass between the spider and surround. This symmetrical design ensures stability under heavy excursion, keeping performance consistent even at extreme output levels. The threaded bolt with wing nut and nylock nut makes adjustment easy and secure, while the included five 116 g weights allow precise control over system tuning.
Extreme-Output Performance — the Ultimate Match for the SS18-22For enthusiasts and designers seeking maximum performance from their subwoofer systems, the Dayton Audio SS18-PR offers the ideal combination of rugged construction, precise tuning, and seamless Signature Series styling. Capable of supporting the most extreme-output subwoofer designs, it makes earth-shaking bass extension achievable without compromise.
