Frequency Response & Impedance

The Dayton Audio PRO-8 is a driver that works well with many different types of horns.

The simple impedance response of the PRO-8 makes crossover design easy!


High Sensitivity

The Dayton Audio PRO-8 has a high sensitivity to keep up with the demands of live audio. An output sensitivity of 107dB means the PRO-8 can keep up when installed in even the most sensitive PA cabinets.
