Automovitve Acoustical Components

A line of acoustical components meets the needs of most navigational systems, Global Positioning Systems, and high-end automotive entertainment systems incorporating DVDs. Two dynamic speakers are available: one is a wide-band dynamic speaker with a resonance frequency of 810 Hz and loudness of 90 dB, and the other is a high SPL dynamic speaker with an 850-Hz resonance and 92-dB loudness. Three omnidirectional microphones have a signal-to-noise ratio of 58 dB minimum. All three weigh only 0.5 gm.
