Dayton Audio Apollo 12LF

voice coil detail



The Dayton Audio Apollo 12LF is an 12" low frequency professional driver that is guaranteed to outperform the stock woofers in your PA system. A 400W power limit 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 12LF packs a lot of punch in a small package. Up to 3/4" P-P cone excursion lets the 12LF go lower and louder for longer. The large motor demands impressive control and allows a low Qt of 0.21, meaning this will shine in small vented enclosures.

An 8 ohm impedance means a pair can be used in as little as 2.3 cubic feet in a small footprint, high output design that handles 800 watts and extends into the low 30's reaching SPL's in excess of 94 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!
