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 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. Features - High density flux ferrite magnet combined with very low carbon content iron plates, for low distortion at high power levels. Low mounting depth, acoustically transparent aluminium alloy basket with elegant diamond cutting and featuring the aluminium Hertz logo. Full protection metal mesh grill featuring the aluminium Hertz logo and attractive look mineral powder coated inner grill are included for several install combinations. 1mm pure copper wire low series resistance inductors, for low dissipation losses on the woofer section where high transient currents are demanded Small footprint design for easy installation, with top vent grille for efficient heat dissipation.
