Celestion CDX1-1425

Celestion CDX: a professional lineage that sets the standard

While Celestion built its legend among guitarists, the CDX series showcases its expertise in sound reinforcement. The CDX1-1425 concentrates the brand's experience into a reliable and high-performance compression driver, designed to deliver precise high-frequency reproduction while remaining easy to integrate into an existing speaker or a new project.

Who is it for and what are the uses?

This compression driver is aimed at technicians, rental companies, and speaker designers looking for a lightweight, efficient, and durable 1 tweeter. Ideal for refurbishing full-range speakers, for compact front-of-house tops, stage monitors, or voice-dedicated speakers, it offers a balanced solution between performance and size.

Design and performance serving intelligibility

Lightweight and practical

The neodymium magnet limits weight without sacrificing efficiency. Weighing only 0.39 kg and with a diameter of about 3.5, the CDX1-1425 facilitates the design of compact systems and on-site replacement.

Extended response and high efficiency

Its frequency response from 2 kHz to 20 kHz covers the high frequencies essential for the clarity of voices and instruments. The sensitivity of 108 dB allows reaching useful levels with less power, for a more efficient system.

Simplified integration

The 1 throat allows mounting on a suitable horn to shape dispersion according to your needs. The 1.40 voice coil and nominal impedance of 8 ohms integrate easily into most common passive crossovers.
