ode· um | \ ō-ˈdē-əm: An ancient Greek and Roman concert hall used for music and poetry.

Using the knowledge from decades of driver design and engineering, Dayton Audio is placing an emphasis on technical excellence, product reliability, and innovation with the Odeum Series of speaker components! The Odeum Series takes the stage with a new line of professional drivers made for any venue.

  • Power Handling (MAX): 2400 Watts
  • Impedance: 8 Ω

  • Voice Coil Diameter: 4"
  • Maximum Linear Excursion: 9.1mm

Frequency Response & Impedance

The Dayton Audio Apollo 18N has a response that matches a large number of horn drivers and tweeters due to its high efficiency in the frequency range of human voices and midrange detail of stringed instruments. The impedance curve of the Apollo 18N makes it easy to pair up with your favorite compression driver without taxing your power amplifiers!

Dayton Audio Pro 18N

The Dayton Audio Pro 18N is an 18" subwoofer that is guaranteed to outperform the stock woofers in your PA system. A 1200W power limit is achieved through the combination of a large neodymium motor, a 4" voice coil with a fiberglass former, and a copper inductance cap to lower distortion. A paper cone with cloth M-roll surrounds provides a neutral tone that is easy to tune, and peripheral venting helps keep the whole system cool when playing!

A solution for every need

We feel we have hit the sweet spot in price and specs in the pro audio market with this workhorse line of subwoofers, midrange, and high-frequency drivers. The ODEUM series consist of two 1200W 18” subwoofers (one neodymium, one ceramic), 5 sizes and various power ratings of neodymium mid-bass, and two 1” exit compression drivers (one bolt-on, one screw-on). Upgrade, replace, or create a new pro sound system with the ODEUM series.
