Celestion CDX: The "Pro Audio" Legacy of a Reference Brand
While Celestion is a staple in the guitar speaker world, the brand has also built a solid reputation in professional sound reinforcement thanks to consistent, reliable, and easy-to-integrate transducers. The CDX1-1070 fits this philosophy: a compression driver from the CDX series designed to deliver consistent performance, whether for maintaining existing speakers or equipping a sound system project. Its widespread use in many systems makes it a reassuring choice for those seeking a proven component capable of long-term reliability.
A Versatile High-Frequency Driver for Sound Reinforcement Speakers and Horn Systems
The Celestion CDX1-1070 is aimed at contractors, integrators, speaker manufacturers, and audio enthusiasts who want clear high-frequency reproduction in a compact format. It is especially suited for front heads, monitors, and full-range speakers using a 1-inch horn. Whether in active or passive crossover configurations, it aims for efficient implementation: delivering clear high-frequency dispersion without needing to oversize power, helping maintain a balanced, responsive, and pleasant-to-listen-to system.

Questions frequently asked
Is the Celestion CDX1-1070 compatible with a 1-inch horn?
The 1-inch throat allows mounting on horns with a 1-inch standard, provided the speaker's mechanical compatibility.
What is the impedance of the compression driver?
The nominal impedance is 8 ohms, a value to consider for passive crossover design and amplifier selection.
From what frequency can it be crossover filtered?
The specified frequency response ranges from 1.5 kHz to 20 kHz. A crossover starting at 1.5 kHz is thus possible with a mid/bass speaker. The filter setting remains crucial for integration into the speaker enclosure.
What power handling does this Celestion high-frequency driver support?
The rated power is 12 W. Its sensitivity of 106 dB allows achieving a high output level with limited power.
Is the CDX1-1070 suitable for replacing a driver in a compact speaker?
Its 2.8-inch diameter and weight of 0.7 kg facilitate integration in compact enclosures. The ferrite magnet is designed for durable use in fixed or mobile sound reinforcement.
