Dayton Audio Reference RS150P-A

The Reference RS150P-A is a high quality bass-midrange driver from Dayton Audio. With a diameter of 6.5" (16.5cm) and an improved three-piece paper composite cone made of paper, Kevlar and glass fibers, this speaker offers excellent sound quality and performance. The technical improvements result in a natural and detailed sound, wide frequency response and an impressive sensitivity of 90.3 dB. Perfectly suited for use as both a woofer and midrange driver or as a pure midrange driver, the RS150P-A sets new standards in its class.

• Now with improved frequency response for easier crossover integration
• Three-part paper composite membrane with paper, Kevlar and glass fibers
• Low-distortion motor, 6-hole cast iron frame, rubber surround and solid aluminum phase plug
• Perfect for use as a woofer and midrange driver or as a pure midrange driver
• 90.3 dB sensitivity and 4.4 mm stroke

Now with improved frequency response - Dayton Audio has revised the design and the result is a much smoother treble roll-off, allowing for wider bandwidth and easier crossover integration.

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 that provides the perfect combination of excellent detail and smooth, natural sound character, as well as a distinctive, refined look.
