Description
The Odeum Apollo 12LF is a 12" low-frequency pro driver from Dayton Audio, designed to outperform the stock woofers in PA systems. A large ferrite motor, a 3" inside-outside wound voice coil on a fibreglass former and extensive venting raise power handling and reduce power compression. A treated paper cone with cloth accordion surrounds gives a neutral tone that is easy to tune, and a progressive spider keeps excursion under control.
Features
- Robust build quality for years of chest-pounding output
- Well-balanced SPL to Xmax ratio for a loud, long-throw sub
- Low Qts and high Bl for small vented enclosures
