Dayton Audio RS100P-4 4" Reference Paper Woofer

The Dayton Audio RS100P-4 4" Reference Paper Woofer is a precision-engineered broadband subwoofer designed to deliver exceptional midrange clarity in compact audio systems. With its 4-inch nominal diameter and 4-ohm impedance, this driver is ideally suited for high-fidelity applications where space is at a premium but sound quality cannot be compromised. Whether you are building a custom bookshelf speaker, a centre channel, or a near-field monitor, the RS100P-4 excels in reproducing vocals and instruments with remarkable accuracy and detail.

Technically, this woofer features a paper/Kevlar cone that combines the natural warmth of paper with the rigidity of Kevlar for reduced distortion. Its sensitivity of 88.5 dB (1m/2.83V) ensures efficient power handling, while the total Q factor (Qts) of 0.54 strikes an excellent balance between sealed and ported enclosures. The 4 mm linear excursion (Xmax) and a displacement volume (Vd) of 15 provide controlled bass extension, and the low voice coil inductance (Le) of 0.26 mH enhances high-frequency response. With a DC resistance (Re) of 3 ohms and a mounting depth of just 51 mm, this driver fits easily into compact designs. The 6-hole mounting pattern and 77.2 mm cutout diameter simplify installation, making the RS100P-4 a versatile choice for discerning audio enthusiasts.
