Overview<\/h1>\n

The Sonic Excellence S1 tweeter is a low distortion inverted PEEK dome 28mm tweeter.\u00a0 This tweeter is optimized for off-axis response.<\/p>\n

The S1 tweeter features a high strength N42H magnet with shorting ring and extended pole piece for wide bandwidth coverage from 2kHz to beyond 20kHz.<\/p>\n

The S1 comes with an integrated chemically etched steel grille featuring an anti-resonant hole-pattern with size of opening optimized for dispersion.<\/p>\n

The S1 features a threaded rear body and a large diameter ABS nut for securing it to panels up to 3\/8″ (9.5mm) thick. Also included is a metal bridge mount to accommodate every type of installation scenario.<\/p>\n
