Dayton Audio Reference RS180P

Discover the Reference RS180P, a 6.5" (16.5cm) bass-midrange driver from Dayton Audio. Part of the renowned Dayton Audio Reference Series, this bass-midrange driver combines the lowest distortion with an exceptionally smooth frequency response thanks to its proprietary paper cone compound. The RS180P meets all requirements, whether as a woofer, midrange driver or dedicated midrange driver, and features a low distortion motor, 6-hole cast frame and solid aluminum phase plug. Its three-piece paper composite cone with paper, Kevlar and glass fibers offers the perfect balance between excellent detail and natural sound.

• Similar cosmetic and design features to the original Reference Series with low distortion motor, 6-hole cast frame, rubber surround and solid aluminum phase plug
• Perfect as a woofer, midrange driver or dedicated midrange driver
• Three-part paper composite membrane with paper, Kevlar and glass fibers
• 6 mm Xmax and 88.2 dB sensitivity

The performance of Dayton Audio's original, groundbreaking Reference Series, now with a paper cone! The Reference Series paper drivers use a proprietary paper cone that combines natural cellulose and synthetic Kevlar® and glass fibers to create an advanced non-woven fiber composite that provides the perfect combination of excellent detail and smooth, natural sound character with a distinctive, refined look.
