Dayton Audio RS100-4 4'' Reference Full-Range Driver

The Dayton Audio Reference RS100-4 is a 4-inch aluminium full-range driver engineered to deliver clear, natural sound reproduction in compact loudspeaker designs. As part of the renowned Reference Series, this driver combines precision engineering with high-quality materials to provide an exceptional audio experience for discerning listeners.

This versatile driver is ideally suited for a wide range of applications, including high-fidelity bookshelf speakers, multimedia systems, and custom audio projects where space is at a premium. Its full-range capability makes it an excellent choice for both stereo and multi-channel setups, delivering articulate vocals and detailed instrumentals without the need for a separate tweeter in many designs. Whether used in a dedicated two-way system or as a standalone driver, the RS100-4 excels in producing a balanced and engaging soundstage.

Technically, the RS100-4 features a rigid aluminium cone that minimises breakup modes for cleaner midrange and extended high-frequency response. The copper voice coil, with an inductance of just 0.28 mH, ensures low distortion and excellent transient behaviour. With a sensitivity of 87.5 dB (1m/2.83V) and a total Q factor (Qts) of 0.53, this driver is optimised for both sealed and ported enclosures, offering flexibility in design. The 4 mm linear excursion (Xmax) and 14.1 cm³ displacement volume (Vd) contribute to impressive low-end output for its size, while the 30 W power handling ensures robust performance.

In summary, the Dayton Audio RS100-4 delivers reference-grade sound quality in a compact, efficient package, making it an outstanding choice for audio enthusiasts seeking high-performance full-range drivers.
