Dayton Audio Apollo 15LF

voice coil detail



The Dayton Audio Apollo 15LF is an 15" low frequency professional driver that is guaranteed to outperform the stock woofers in your PA system. A 500W power rating is achieved through the combination of a large ferrite motor, a 3" inside-outside wound voice coil with a fiberglass former, and extensive venting to increase power handling and reduce power compression. A treated paper cone with cloth accordion surrounds provides a neutral tone that is easy to tune, and a progressive spider helps keep cone excursion under control.

Built to Blast



The Dayton Audio Apollo 15LF packs a lot of punch in a small package. Up to 3/4" P-P cone excursion lets the 15LF go lower and louder for longer. The large motor demands impressive control and allows a low Qt of 0.26, meaning this will shine in small vented enclosures.

A single 15LF can be used in as little as 3.5 cubic feet in a small footprint, high output design that handles 700 watts and extends into the mid 20's reaching SPL's in excess of 96 dB!

Compare the Apollo LF family of woofers to others in their class and you will see that you can achieve all of the same performance, for as little as half the price of the competition!
