Description
The Beyma SC6903 is a 6-by-9-inch coaxial speaker pair designed for broad-band mobile-audio reproduction from common oval factory locations. Each speaker combines a low-/mid-frequency cone and high-frequency section in one frame.
The 4-ohm pair is rated for 100 watts RMS per published manufacturer data, with 91 dB sensitivity. The current technical table lists the low-frequency section from 40 Hz to 2 kHz but does not separately publish the combined coaxial upper-frequency limit.
