The F7, too, features ADAM Audio’s proprietary Accelerating Ribbon Technology, the most famous of all ADAM inventions, assuring for utmost clarity of the high frequencies. The 7” carbon/paper-midwoofer comes with a 37mm voice coil. It has been designed to perfectly complemet the ART tweeter. It stars in both the deep registers and the musically crucial midrange. The F7 shares the same controls one finds in the F5: a volume knob (- infinity to +6dB) and two room EQ’s for both the high (>5kHz) and the low (<300Hz) frequencies.
