Precision Devices PD.CD2N, 1.4″ exit, neodymium Compression Driver was reviewed in the February 2018 edition of Voice Coil Magazine’s Test Bench.
“The PD.CD2N, from UK Pro Sound OEM manufacturer Precision Devices, is part of Precision Devices’ seven model lineup of high-performance neodymium compression drivers. Six of the models, including the PD.CD2N, feature titanium diaphragms (one uses Peek diaphragm material), as well as utilizing a three-slot optimized phase plug design. The PD.CD2N has a 50.8 mm (2”) throat diameter and is driven by a titanium diaphragm with a 72.2 mm (2.84”) diameter voice coil wound with aluminum wire on a Kapton former. Other features include a radial neodymium magnet motor structure, an aluminum three-slot phase plug, nominal 105 W (AES) rated power handling, a 1.6 kHz recommended crossover frequency, and color-coded chrome push terminals. Since Precision Devices does not manufacture horns, I mated the compression driver up to a B&C Speakers ME60 constant directivity 2” throat 60°H × 40°V aluminum horn with a 0.8 kHz cutoff frequency…”Vance Dickason, Voice Coil
