Dayton Audio Odeum Apollo 12N 12MB400N-8

The Odeum Apollo 12N 12MB400N-8 is a 12" (30cm) bass-midrange driver from Dayton Audio. This technically flawless and reliable model is aimed at professional users and offers a variety of highlights, including a powerful neodymium motor and a copper induction cap for excellent output and minimal distortion. With design features such as a paper cone and a fabric M-roll surround, it doesn't compromise on clarity and rich output. It is also designed to ensure cooler voice coils thanks to ventilation holes both under the spider and at the rear periphery. In addition, its low Qts value enables high damping and the use of smaller cabinets.

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 12 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 taxing your power amplifiers!

The Apollo 12 is a 12" 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 professional sound system.
