Dayton Audio DS135-8 5" Designer Series Woofer

The Dayton Audio DS135-8 5" Designer Series Woofer Speaker is a precision-engineered component designed to deliver accurate bass and mid-bass reproduction in a variety of audio projects. This 5-inch woofer, part of the respected Designer Series, combines a treated paper cone with a robust motor structure to achieve a smooth frequency response and low distortion, making it an ideal choice for both DIY enthusiasts and professional system builders.

This versatile driver excels in applications such as compact two-way loudspeakers, multi-channel home theatre systems, and high-fidelity subwoofer designs where controlled, articulate low-end performance is essential. Its balanced parameters allow it to work effectively in sealed or ported enclosures, providing clean, punchy bass that integrates seamlessly with mid-range and tweeter drivers.

Key technical features include a copper voice coil wound on a high-temperature former, offering an inductance of 0.84 mH and a DC resistance of 5.9 ohms. The woofer achieves a linear excursion (Xmax) of 4.85 mm, with a displacement volume (Vd) of 36.6 cm³. Its Thiele-Small parameters—Qts 0.39, Qes 0.48, and Qms 2.02—indicate a well-damped response suitable for accurate bass reproduction. Sensitivity is rated at 86.6 dB SPL (2.83V/1m), and the treated paper cone ensures natural sound character with minimal breakup.

With a nominal diameter of 88.9 mm, a mounting cut-out of 111.5 mm, and a depth of 68.6 mm, this woofer is straightforward to integrate into custom enclosures. The DS135-8 represents an excellent balance of performance and value for discerning audio projects.
