Description
The Dayton Audio Reference RS270P-A is a 10" (25cm) woofer with a high-quality design. This woofer not only stands out due to its striking appearance, but also offers a lot technically. With the help of a special cone mixture, it delivers an incredibly smooth frequency response and has very low distortion values thanks to a three-part composite cone made of paper, Kevlar and glass fibers. Suitable as a woofer, midwoofer or dedicated midrange driver, it turns your system into a real eye-catcher. Despite its high performance, it manages to deliver a natural and smooth sound. Find out more and let its capabilities convince you!
