Scan-Speak D2008/8512 Double chambered 3/4" damped textile dome tweeter. The voice coil is a precision wound aluminum wire with a 27 strand tinsel braid for a lower resonance. The magnet system is a special high flux ferrite with vented pole plates. The surround of the diaphragm is damped to reduce distortion. This tweeters extremely linear response, low distortion and wide dispersion make it an attractive choice for any speaker system.
