SB Acoustics SB26ADC-C000-4 / Aluminum Dome Tweeter

The SB Acoustics SB26ADC-C000-4 is a 1″ (26 mm) aluminum dome tweeter designed to deliver crisp, detailed highs with a touch of metallic sparkle, all while maintaining smooth frequency response and low distortion. It’s an excellent option for those who prefer a more analytical and revealing top end compared to soft domes.

Features

• Phase optimized diaphragm design for coherent high frequency radiation
