With the knowledge gained from decades of experience in loudspeaker design and construction, Dayton Audio's Odeum Series focuses on technical excellence, product reliability and innovation! The Odeum Series is a new range of professional loudspeakers suitable for any venue.

The Dayton Audio Apollo 15 has a frequency response to rival many horn drivers due to its high efficiency in the frequency range of human voices and the midrange of stringed instruments. The Apollo 6's impedance curve makes it easy to pair with your favorite tweeters without overloading your power amplifiers!

The Apollo 15 is a 15" mid-woofer that is guaranteed to outperform the standard woofers in your PA system. By combining a neodymium motor, a 3" voice coil with a glass fiber support and a copper induction cap to reduce distortion, a maximum output of 200 W is achieved. A paper cone with fabric M-roll surrounds provides a neutral sound that is easy to tune, and perimeter venting keeps the whole system cool while playing!

Dayton Audio believes they have hit the sweet spot of the pro audio market in terms of price and features with this series of subwoofers, midrange drivers and tweeters. The ODEUM series consists of two 1200 W 18" subwoofers (one neodymium, one ceramic), neodymium mid-woofers in 5 sizes and different power levels and two 1" output compression drivers (one screw-on, one screw-on). With the ODEUM series you can upgrade, replace or build a new professional sound system.
