Ipswich, U.K. (July 17, 2009)--Celestion has introduced its CDX1-1720, a 1-inch exit, neodymium-magnet, titanium-dome compression driver. This product features a "next-generation" design phase plug, developed at Celestion's U.K. headquarters.

Offering 50W rms continuous power handling and 107 dB sensitivity, the CDX1-1720 reportedly exhibits much lower distortion than many typical devices already on the market. This technology, already used on Celestion's latest large-format compression drivers, has now been adapted for use with a 1-inch exit device.

The technology revolves around a patent-applied-for method, developed by head of group research Mark Dodd and his team, to calculate key dimensions within the compression driver's phase plug. According to the company, this delivers a much lower distortion performance thanks to the suppression of cavity resonances at higher frequencies. The resulting lower compression ratio reduces air nonlinearity and allows for higher maximum SPL.

The compression driver also features a deep-drawn titanium diaphragm, for increased stiffness. This reportedly creates a higher threshold frequency, avoiding the dome break-up (distortion)--within the midrange listening band of 2-10 kHz--that is associated with the lower-profile diaphragms of typical compression drivers.
