These two models provide designers with a choice of mounting options (the CDX1-1730 is flange mount and the CDX1-1731 screw mount), while specifications for both products are the same: 75-Watt power rating, 8_ impedance, 110dB sensitivity, 1.2-20kHz frequency range, 1.75″ voice coil and 1″ throat exit with a PETP film diaphragm.
According to senior project engineer, Paul Cork “These compression drivers bring together the best elements of technology used in all of our CDX range. The design extracts the maximum performance from a very low profile unit.”
And, like other CDX compression drivers in the range, these new devices make extensive use of Celestion’s industry-leading experience in Finite Element Analysis (FEA) to optimize the magnetic and acoustic design, helping the CDX1-1730/1731 to achieve outstanding performance at a highly competitive price point.
The new compression drivers also use Celestion’s proprietary Sound Castle™ diaphragm clamping system to ensure even clamping pressure on the diaphragm surround, thereby reducing distortion while allowing the full internal volume of the rear cover to act as a loading chamber for the diaphragm, resulting in superior lower mid-band response. With exceptional heat management from the aluminum heatsink, an edge-wound coil, a choice of mounting options, the CDX1-1730/1731 represents a cost-effective, high performance HF solution for a wide variety of sound reinforcement applications.
Thanks to significant and sustained investment in research and development, Celestion will be launching new products throughout this year. Winter NAMM 2007 sees the first phase of this initiative with no fewer than 24 new products being introduced, including the CDX compression drivers.
