Celestion 1.75in Bolt-On Compression Driver, 40W RMS 8 Ohm

The Celestion 1.75in Bolt-On Compression Driver is a professional high-frequency driver engineered to deliver the optimum balance between performance, efficiency, weight, and cost. It provides a detailed and dynamic mid and high-frequency response, making it a reliable choice for demanding audio applications.

At its core is a reliable and durable PETP film diaphragm, secured by Celestion's innovative 'Sound Castle' diaphragm clamping system. This ensures consistent performance and longevity. The driver features a matched wavefront phase corrector for improved sonic accuracy and an anisotropic ferrite magnet with precision plates for powerful and efficient motor strength.

Key to its performance is the 1.75in (44mm) copper-clad aluminium voice coil, which handles power effectively while maintaining clarity. Custom 'O' rings are employed to achieve perfect acoustic seals between the terminals, magnet, and cover, minimising air leaks and distortion. The convenient bolt-on mounting simplifies installation into compatible horn assemblies.

With a power handling of 40W RMS and an 8-ohm impedance, this driver is built for integration into professional sound systems. Its high sensitivity of 110dB ensures efficient conversion of amplifier power into acoustic output, while the broad frequency response from 1.2kHz to 20kHz covers the critical upper midrange and treble spectrum.
