Dayton Audio RS125P-4 5" Reference Paper Woofer

The Dayton Audio RS125P-4 5" Reference Paper Woofer delivers precise, natural midbass reproduction for discerning audio enthusiasts. This 4-ohm driver is engineered to bring clarity and warmth to a variety of applications, making it an ideal choice for high-fidelity loudspeaker designs, studio monitors, and custom audio projects where accurate bass and midrange performance are essential. Whether you are building a two-way bookshelf speaker or a dedicated subwoofer system, this woofer excels in producing controlled, articulate low frequencies that complement any soundstage.

At the heart of the RS125P-4 lies a paper and Kevlar composite cone, which offers an excellent balance of stiffness and damping for a clean, uncoloured response. The copper voice coil, with an inductance of just 0.32 mH, ensures low distortion and high efficiency, while the 90 dB sensitivity (1m/2.83V) allows for ample output with modest amplifier power. Key technical parameters include a total Q factor (Qts) of 0.48, a mechanical Q (Qms) of 3.19, and an electrical Q (Qes) of 0.57, indicating a well-damped driver suitable for sealed or ported enclosures. With a maximum linear excursion (Xmax) of 4 mm and a displacement volume (Vd) of 21.1 cm³, this woofer delivers tight, impactful bass. The 127 mm nominal diameter and 55 mm mounting depth fit neatly into compact designs, while the 94 mm cutout diameter and six mounting holes simplify installation. Priced at 24,990 HUF, the RS125P-4 is a refined choice for those seeking authentic, reference-grade sound.
