Installation & Compatibility
The ML 700.3 is designed for high-quality front systems in vehicles. Use it as a midrange speaker in an active or passive 3-way setup. For high power handling, a high-pass filter around 250 Hz with 12 dB/octave is recommended (corresponding to the peak specification). Pay attention to the mounting holes and depth according to the dimensioned drawing to avoid resonances and ensure proper ventilation of the drive.
