ASP (Automatic Speaker Presence) is required when the AP8.9 bit amp is installed and designed to solve problems associated with signal interference or deactivation of OEM amplifiers when there is no speaker load.
The MPCX 2 TM.3 car audio crossover is specifically developed for MP 70.3 and MP 25.3 when installed in a 3-way multi-amplification system and combined with an MP 165.3/ MP 165P.3 woofer actively driven.
Much time was invested in the research of the perfect material for the C 165 woofer cones: through a long process of customization of the materials SPP-M was selected (Semi Pressed Paper-Mica), which preserves the natural sound of the semi-pressed paper and enhances it with Mica powder improving rigidity. The result is an excellent balance between lightness and damping, essential for a powerful and controlled emission. The oversized ferrite magnet provides excellent control even at higher excursions.
