Overview<\/h1>\n

The High Fidelity H1 tweeter is a high stroke, low distortion multilayer fabric dome 25mm tweeter.\u00a0 This tweeter features exceptionally high stroke to allow lower crossover points without compression.<\/p>\n

The H1 tweeter features a split-gap design which provides \u00b11.4mm of linear excursion, approximately 5 to 6 times that of most other tweeters. The result is a wider operational bandwidth \u2013 as low as 1500 Hz \u2013 and distortion reduced by up to a factor of 4.<\/p>\n

The H1 uses a specially developed dome material.\u00a0 The dome\u2019s fabric is a lamination of silk, polyester, and cotton and treated with a proprietary compound to unify the layers but allow each to provide their own unique benefits.\u00a0 Silk adds the stretch\/pull basic mechanical strength; polyester provides rigidity of shape; cotton provides improved damping.<\/p>\n

The H1 does not use a rear chamber to lower its resonance; instead, a larger roll surround provides a lower resonance of the driver.\u00a0 This design allows for higher stroke as well, for full-range output down to 1500 Hz.\u00a0 And by removing the rear chamber, resonances from that chamber are eliminated. The elimination of the rear chamber results in an 11.2mm (7\/16\u201d) mounting depth for freedom of positioning.<\/p>\n

The H1 comes with an integrated chemically etched steel grille featuring an anti-resonant hole-pattern with size of opening optimized for dispersion.<\/p>\n

The H1 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 45 degree surface cup and metal bridge mount to accommodate every type of installation scenario.<\/p>\n
