Dayton Audio RS100P-8 4" Reference Paper Midwoofer

The Dayton Audio Reference RS100P-8 Paper Midwoofer is a meticulously engineered 4-inch driver that brings exceptional clarity and natural warmth to any audio system. Designed for audiophiles and DIY enthusiasts alike, this midwoofer excels in delivering accurate midrange reproduction, making it an ideal choice for high-fidelity loudspeakers, studio monitors, and custom multi-way designs. Its versatile performance also suits compact bookshelf speakers and small-scale sound reinforcement applications where precise vocal and instrumental detail is paramount.

At the heart of the RS100P-8 lies a paper/Kevlar composite cone, which combines the organic, detailed character of paper with the strength and rigidity of Kevlar for controlled, low-colouration sound. With a total Q factor (Qts) of 0.54, this driver offers excellent flexibility for both sealed and ported enclosures, allowing you to tailor the bass response to your preference. The 86.2 dB sensitivity ensures efficient power handling, while a maximum linear excursion (Xmax) of 3.7 mm and a displacement volume (Vd) of 13.8 provide robust, dynamic output. Additional technical highlights include a low voice coil inductance (Le) of 0.51 mH for extended high-frequency response, and a carefully optimised electromagnetic Q (Qes) of 0.71 for tight, controlled bass. The 6-hole mounting design and 77.2 mm cutout diameter simplify installation, while the 51 mm depth suits compact cabinets.

Whether you are building a reference-grade speaker or upgrading an existing design, the RS100P-8 delivers the precision and musicality expected from Dayton Audio’s Reference series.
