Test Bench: Celestion CDX1-1742 1” Exit Pro Sound Compression Driver
For this month's Test Bench, Vance Dickason characterizes the CDX1-1742 from legendary UK Pro Sound OEM manufacturer Celestion. This driver joins the CDX family of ferrite motor compression drivers, and is designed for use with 1” throat horns, featuring a FEA-optimized ferrite magnet motor structure, and a proprietary next-generation “Sound Castle” soft diaphragm clamping assembly that reduces diaphragm mechanical stress and distortion. For this Test Bench, Celestion supplied the H1-9040P horn, with a 90° × 40° coverage pattern. This article was originally published in Voice Coil, May 2018.
