Components Resistors: metaloxide, high power and precision, non inductive;
Inductors: 1 mm copper coil, low resistance, high saturation flux;
Capacitors: polyester film, 100 Vdc, very low DF;
Layout: 1.7 mm shockproof FR2 with very thick pads.
Crossover Frequency Cut-off frequencies have been chosen for the best acoustic crossover point.
The study of the reverberating field in cars, which interacts with the system response,
recommended the use of open electrical cuts with optimised damping.
Attenuation slopes are 12dB/Oct.
