Test Bench: Two Beryllium Tweeters from Scan-Speak - D3004-604010 and the D3004-604000

These two new beryllium diaphragm neodymium motor tweeters, the D3004/604010 and the D3004/604000, basically share the same platform, with the major difference being the D3004/604010 has a lower Fs due to the larger rear cavity. Both tweeters use a Materion 26-mm 99% pure beryllium dome. This article was originally published in Voice Coil, May 2016
