Dayton Audio PCS115-8 Poly Cone Woofer

The Dayton Audio PCS115-8 is a compact yet powerful 4-inch poly cone subwoofer, engineered to deliver tight, controlled bass in space-constrained applications. As part of the renowned Dayton Audio range, this 8-ohm driver is ideal for audiophiles and DIY enthusiasts seeking to enhance low-frequency performance without compromising on cabinet size. Whether you are building a small sealed subwoofer for a desktop audio system, a ported enclosure for a home theatre setup, or integrating it into a custom car audio project, the PCS115-8 offers remarkable versatility and precision.

Technically, this subwoofer features a polypropylene cone that ensures stiffness and durability while minimising distortion, resulting in clean, articulate bass. With a total Q factor (Qts) of 0.84, it is well-suited for both sealed and ported enclosures, providing a balanced response. The 2.75 mm linear excursion (Xmax) allows for substantial cone movement, while the 82.5 dB sensitivity ensures efficient power handling. The 6.8-ohm DC resistance and 0.55 mH voice coil inductance contribute to stable electrical performance. Mounting is straightforward with a 95 mm cut-out diameter and four screw holes on a 109.5 mm bolt circle. The PCS115-8 is a reliable choice for achieving deep, controlled bass in compact designs.
