Dayton Audio DS115-8 4" Designer Series Woofer

The Dayton Audio DS115-8 4" Designer Series Woofer Speaker is a precision-engineered component designed to deliver accurate mid-bass reproduction in compact loudspeaker systems. As part of the esteemed Designer Series, this woofer combines refined acoustic engineering with a compact footprint, making it an ideal choice for audiophiles and DIY enthusiasts seeking high-fidelity sound in space-constrained applications.

This 4-inch woofer excels in sealed and ported enclosures, where its carefully optimised parameters ensure smooth, natural bass extension. It is particularly well-suited for use in bookshelf speakers, centre channels, and small subwoofer systems, as well as for upgrading existing multi-way designs where accurate mid-bass performance is critical. The treated paper cone provides a warm, natural sound signature that integrates seamlessly with tweeters and midrange drivers.

Technically, the DS115-8 features a total Q factor (Qts) of 0.38, enabling a balanced response in both sealed and vented cabinets. With an Xmax of 4.1 mm and a displacement volume (Vd) of 22.2, it delivers impressive linear excursion for its size. The 5.8 ohm DC resistance and 0.8 mH voice coil inductance ensure efficient power handling, while the copper voice coil wire and treated paper cone contribute to low distortion and reliable performance. The woofer’s 93.6 mm cutout diameter and four mounting holes simplify installation.

Combining compact dimensions with high-quality construction, the Dayton Audio DS115-8 is a versatile and reliable choice for achieving accurate, natural mid-bass in your next speaker project.
