Dayton Audio RS180-8 7" Reference Woofer

The Dayton Audio RS180-8 7" Reference Woofer is a premium-grade bass and mid-bass driver engineered for audiophiles and DIY enthusiasts who demand exceptional clarity and precision. This 7-inch woofer delivers accurate, low-distortion performance, making it an ideal choice for high-fidelity loudspeaker designs, studio monitors, or custom home theatre systems. Its aluminium cone and robust motor structure ensure controlled, articulate sound reproduction across the critical midrange and upper bass frequencies.

Use cases for this driver include two-way or three-way speaker builds, where it excels as a dedicated mid-bass unit or a subwoofer in compact enclosures. With a total Q (Qts) of 0.31 and a linear excursion (Xmax) of 6mm, it is well-suited for sealed or ported designs, offering tight, punchy bass without sacrificing detail. The 87.1 dB sensitivity (2.83V/1m) ensures efficient power handling, while the 6.4 ohm DC resistance (Re) provides stable impedance for amplifier matching.

Technical features include a copper voice coil wire with an inductance (Le) of 0.73 mH, contributing to low distortion and extended frequency response. The aluminium cone and 180.5mm frame diameter (with a 146mm cutout) offer rigidity and easy integration. The electromagnetic Q (Qes) of 0.42 and displacement volume (Vd) of 74.8 cm³ further enhance its ability to produce clean, dynamic sound. With a depth of 81mm and six mounting holes, installation is straightforward.

In summary, the RS180-8 is a reference-grade woofer that combines advanced engineering with versatile application, delivering exceptional performance for discerning audio projects.
