2021 TECnology Hall of Fame Recognizes the Work of Audio Pioneers

While audioXpress did highlight already the 36th Annual NAMM Creative and Technical TEC Awards when those were announced, because there was no actually NAMM show this year (and no actual TEC Award ceremony) we still needed to confirm the 2021 TECnology Hall of Fame Inductees. These are awards also confirmed every year to honor and recognize audio products and innovations that have made a significant contribution to the advancement of audio technology.

The transducer Celestion sent for this Test Bench joins the extensive CDX line of neodymium motor compression drivers. Designed for use with 1.4” throat horns, the CDX14-3040 is driven by a 75 mm (3") diameter voice coil wound with edge-wound copper clad aluminum wire (CCAW) on a non-conducting former driving a single-piece titanium diaphragm and surround. Celestion also supplied its new 1.4” H14-7050 70°x50° constant directivity horn. This article was originally published in Voice Coil, April 2020.

This article focuses on another pro sound OEM new to Voice Coil’s Test Bench, Oberton of Bulgaria. For this characterization, Oberton supplied the recently released ND72CT/HB 1.4" compression driver along with the H-1464 1.4” cast aluminum 60° × 40° constant directivity horn. The ND72 has two iterations available - a cotton composite diaphragm with polycotton surround - The ND72CT - and an alternative dome, named the Hybrid Dome, using a combination of carbon composite diaphragm with a center cotton composite “patch” that reduces break-up modes - the ND72HB.
