Dayton Audio RS150P-4A 6" Reference Paper Woofer

The Dayton Audio RS150P-4A 6" Reference Paper Woofer is a meticulously engineered driver designed to deliver accurate, natural mid-bass reproduction for discerning audio enthusiasts. This 4-ohm woofer excels in a variety of applications, including high-fidelity two-way loudspeakers, compact subwoofer systems, and automotive audio upgrades where precise bass response and clarity are paramount. Its controlled performance makes it an ideal choice for both DIY projects and professional installations seeking to achieve a balanced, musical soundstage.

Technically, this woofer features a paper and Kevlar composite cone that combines lightweight rigidity with excellent damping properties, ensuring low distortion and a smooth frequency response. With a total Q factor (Qts) of 0.34, it is well-suited for sealed and ported enclosures, offering tight, articulate bass. The 4.4 mm linear excursion (Xmax) and 37.4 cm³ displacement volume (Vd) enable robust output, while a sensitivity of 90.3 dB (1m/2.83V) ensures efficient power handling. Additional specifications include a DC resistance (Re) of 3.5 ohms, a voice coil inductance (Le) of 0.39 mH, and a mechanical Q (Qms) of 1.85 with an electromagnetic Q (Qes) of 0.42. The woofer requires a 121.5 mm cutout and has a mounting depth of 73.5 mm, with six mounting holes for secure installation. Combining reference-grade engineering with versatile performance, the RS150P-4A is a superb foundation for any high-quality audio project.
