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<p>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<p>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<p>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<p>The H1 features a threaded rear body and a large diameter ABS nut for securing it to panels up to 3\/8&#8243; (9.5mm) thick. Also included is a 45 degree surface cup and metal bridge mount to accommodate every type of installation scenario.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-large wp-image-6286\" src=\"https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-906x1024.jpg\" alt=\"\" width=\"900\" height=\"1017\" srcset=\"https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-906x1024.jpg 906w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-scaled-600x678.jpg 600w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-265x300.jpg 265w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-768x868.jpg 768w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-1359x1536.jpg 1359w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-1812x2048.jpg 1812w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-53x60.jpg 53w, https:\/\/adcaraudio.com\/store\/wp-content\/uploads\/H1-DIMENSIONS-80x90.jpg 80w\" sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\n<h2>Thiele Small Parameters<\/h2>\n<table>\n<tbody>\n<tr>\n<td width=\"312\">Impedance<\/td>\n<td width=\"312\">4 Ohms<\/td>\n<\/tr>\n<tr>\n<td width=\"312\">Nominal SPL<\/td>\n<td width=\"312\">89 dB @ 1W, 1m (92 dB @ 2.83Vrms, 1m)<\/td>\n<\/tr>\n<tr>\n<td width=\"312\">Resonant Frequency<\/td>\n<td width=\"312\">1500 Hz \u00b110%<\/td>\n<\/tr>\n<tr>\n<td width=\"312\">THD @ 100 dB, 4<sup>th<\/sup> order high pass @ 1500 Hz<\/td>\n<td width=\"312\">Less than 1%, 1 meter<\/td>\n<\/tr>\n<tr>\n<td width=\"312\">Max power handling<\/td>\n<td width=\"312\">400W, 4<sup>th<\/sup> order high pass @ 4000 Hz<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<h3><\/h3>\n<ul>\n<li>8&#8243;
