Dayton Audio RS100-8 4" Reference Full-Range Driver

The Dayton Audio RS100-8 4" Reference Full-Range Driver is a compact yet powerful broadband driver designed to deliver exceptional clarity and detail across the entire audio spectrum. As a full-range unit, it eliminates the need for a separate tweeter in many applications, making it an ideal choice for high-fidelity loudspeakers, desktop monitors, and portable audio projects where space is at a premium. Its versatility also extends to use in multi-channel home theatre systems or as a dedicated midrange driver in more complex designs.

Technically, this driver features a lightweight aluminium cone that ensures rapid response and low distortion, while the 3.5mm linear excursion (Xmax) allows for impressive dynamic range despite its modest 4-inch nominal diameter. The total Q factor (Qts) of 0.58 indicates a well-damped character suitable for both sealed and ported enclosures, offering flexibility in cabinet design. With a sensitivity of 84.6 dB SPL (1m/2.83V) and a DC resistance of 6.4 ohms, it pairs efficiently with typical amplifier loads. The copper voice coil wire and 0.5 mH inductance contribute to smooth, extended high-frequency response, while the 77.2mm cutout diameter and six mounting holes simplify installation. Whether for a refined bookshelf speaker or a custom audio project, this driver delivers reference-grade performance in a compact form.
