75W 8 Ohm NEO Compression Driver
Celestion's CDX14-3040 neodymium magnet compression driver is a perfect example of our commitment to continual refinement. It stands on the shoulders of industry giants; based on a traditional design approach to deliver a high quality HF response with a familiar sonic character. It offers several performance advantages over its predecessors, including lower overall distortion, and reduced size and weight.
We have taken a more scientific approach to the tried-and-tested large format compressiondriver design, with the rigorous application of finite element analysis (FEA), enabling Celestionto better optimize and enhance the design, improving the performance beyond that of therecognised industry standard devices.The CDX14-3040's diaphragm surround has a periodic geometry, which effectively eliminatescircumferential modes while still allowing for linear excursion. A high-temperature polymer clampring is optimized for stiffness through its geometry, ensuring that the dome is always held rigidand preventing the diaphragm from bending. The diaphragm assembly is located into the magnetwith a precision-cut aluminium locating ring. This is probably one of the most important parts ofthe driver, but so often overlooked. The locating ring ensures the coil is always held concentric tothe magnet gap, as any offset of the can allow it to hit the magnet assembly. Between the coverand the clamp ring is a semi-rigid layer of a polymer similar to rubber, which spreads clampingpressure more evenly across the diaphragm assembly. This means that the diaphragm assembly ismore likely to stay flat, holding the dome without allowing it to deform.
