The D3644 is 1.4” high frequency compression driver, improved version of D3645, with reduced weight. It is designed for a wide variety of applications including budged projects requiring 1.4" driver of high quality. The new phasing plug design, copper inductance ring and new dome ensure low distortion at the high sound levels. The D3644 offers all the benefits of the comperssion driver in a 1.4" format, but at much reduced cost.
