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

The Dayton Audio Apollo 18N has a frequency response that rivals many horn drivers and tweeters, as it is highly efficient in the frequency range of human voices and the midrange of stringed instruments. The Apollo 18N's impedance curve makes it easy to pair with your favorite compression driver without stressing your power amps!

The Apollo 18N is an 18" subwoofer that is guaranteed to outperform the standard woofers in your PA system. Combining a large neodymium motor, a 4" voice coil with a fiberglass carrier and a copper induction cap to reduce distortion, it achieves a maximum power of 1200W.A paper cone with fabric M-Roll surrounds provides a neutral sound that's easy to tune, and all-round ventilation ensures the whole system stays cool while you play!

Dayton Audio is the  Opinion that with this series of subwoofers, midrange speakers and tweeters they have hit the sweet spot of the pro audio market in terms of price and features.  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 bolt-on). With the ODEUM series you can upgrade, replace or build a professional sound system.
