Description
The Beyma SC603 is a 6.5-inch coaxial speaker pair designed for broad-band mobile-audio reproduction from factory-style mounting locations. Each speaker combines a low-/mid-frequency cone and high-frequency section in one frame.
The 4-ohm pair is rated for 75 watts RMS per published manufacturer data, with 90 dB sensitivity. The current technical table lists the low-frequency section from 50 Hz to 2 kHz but does not separately publish the combined coaxial upper-frequency limit.
