Dayton Audio Pro 12N Odeum Speaker Driver Woofer Midbass Paper 400W 8Ω 96.6dB 40Hz-5600Hz Ø30.48cm
Dayton Audio presents its Odeum range of high-end professional speakers. The Pro 12N is a bass/midrange driver with incredible performance. It is based on a careful, intelligent design, enabling it to be installed in demanding systems requiring high power reproduction with fidelity.
Frequency response & Impedance
The Dayton Audio Pro 12N has a response that matches many horn and tweeter speakers, thanks to its high efficiency in the frequency range of human vocals and the midrange detail of stringed instruments. The speaker's impedance curve makes it easy to combine with a compression driver without straining your power amplifiers.
Flawless design
The Dayton Audio Pro 12N is a 12" bass/midrange driver capable of outperforming the standard woofers of many PA systems. The 400Wrms power limit is achieved thanks to the combination of a neodymium motor, a 3" voice coil with fiberglass support and a copper inductance cap to reduce distortion. A paper cone with M-Roll fabric suspensions provides a neutral, easy-to-tune sound. The peripheral opening keeps the whole system ventilated.
