Frequency Response & Impedance
The Dayton Audio Apollo 18F 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 18F makes it easy to pair up with your favorite compression driver without taxing your power amplifiers!
Apollo 18F
The Apollo 18F 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 ferrite 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.
