Description
The Dayton Audio Reference RS125P is a 5" (13cm) bass-midrange driver in a class of its own. This unique bass-midrange driver surprises with a three-part paper composite cone made of paper, Kevlar and glass fibers. Its extraordinary construction is reflected in a design that corresponds to the renowned Reference series and scores with a low-distortion motor, 6-hole cast frame, rubber surround and a solid aluminum phase plug. The performance of the RS125P is not only reflected in its construction: it is perfectly suited for use as a woofer, midrange driver or dedicated midrange driver and always delivers the expected quality.
