Peerless by Tymphany SDS-P830878 3-1/2" Passive Radiator

The Peerless by Tymphany SDS-P830878 3-1/2" Passive Radiator offers a refined solution for enhancing low-frequency performance in compact loudspeaker systems. Designed to replace traditional port tubes, this passive radiator delivers smooth, natural bass extension without the tuning challenges or chuffing noise often associated with reflex ports. It is ideally suited for small to medium-sized enclosures where space is at a premium, making it a popular choice for bookshelf speakers, soundbars, and custom audio projects seeking deeper, more controlled low-end response.

Constructed with a treated paper cone and a durable rubber surround, this radiator combines lightweight responsiveness with long-term reliability. The treated paper membrane ensures articulate, musical bass reproduction, while the rubber surround provides excellent linear excursion and damping characteristics. The steel basket offers robust structural integrity, reducing unwanted resonances and ensuring consistent performance over time. As part of the Peerless by Tymphany SDS series, this 3.5-inch passive radiator is engineered to work seamlessly with matching active drivers, delivering a cohesive and extended low-frequency output that enriches the overall listening experience. Whether upgrading an existing design or building from scratch, the SDS-P830878 is a versatile and high-quality component for achieving impressive bass in a compact footprint.
