Celestion tackles directivity trade-offs with PXT6000

Controlled directivity and smooth frequency response have traditionally involved a compromise for loudspeaker designers, however Celestion claims to have eliminated that trade-off with the introduction of its new PXT6000 compression driver.

The driver is built around the company’s new patented Planar eXit Technology (PXT), a wave-shaping approach developed using advanced mathematical modelling, which is said to deliver a highly coherent rectangular pressure wave that enables both precise directivity control and an exceptionally smooth frequency response from the same device. The design is based around a deep-drawn titanium diaphragm and has been engineered to reduce throat resonances that can colour the sound of conventional compression drivers. Celestion also states that the coherent wavefront improves efficiency and intelligibility when multiple devices are arrayed together by reducing interference effects and power loss.

Alongside the new wave-shaping technology, the PXT6000 features a compact cast-aluminium waveshaper with a rectangular 165x20mm exit intended to improve loading and off-axis performance. The driver utilises a neodymium magnet assembly and a 3-inch edgewound copper clad aluminium voice coil. Specified at 240W continuous power handling, with a nominal rating of 120W and an impedance of 8Ω, the PXT6000 covers a frequency range from 500Hz–20kHz and is aimed at high-end professional sound reinforcement array applications.
