The MPK 165.3 car audio speakers system has been designed to ensure a wide low frequency response, even in cars with no space for a subwoofer. Thanks to the V-cone® and Boundary Free Surround technologies the MP 165.3 woofer boast outstanding dispersion features and generates high SPL with compact dimensions. The dedicated crossover MPCX 2.3 has been designed to exploit the wide extension of the MP 165.3 woofers , ensuring a natural transition towards the MP 25.3 tweeter, for maximum natural acoustic emission. The 1mm low parasitic resistance copper filter coil of the woofer maximizes its efficiency. The MPCX 2.3 crossover features tweeter level (0/+2 dB) to calibrate the MP 25.3 acoustic emission level comparing it to the woofer one.
