Fane CD.140S (CD140S) 1" 40W AES Compression Driver 8 Ohm
The CD140S is an excellent choice for professionals who are looking to achieve high sound pressure level performance and clarity of sound from compact dimensions. The compression driver exit diameter is an industry standard 1 inch (25.4mm). The CD140S combines high BL and a lightweight diaphragm assembly to produce a very high output device that also features extended bandwidth and well defined frequency response. The CD140S is optimised for high performance system designs. The driver has a rated low frequency response limit of 2 kHz and features extended response to 18 kHz. The throat diameter and fixings are industry standard and will will match to commercially available high frequency horns. The ferrite based permanent magnetic system produces a very high efficiency to weight and size ratio. This makes the CD140S ideal for high level professional touring applications as well as high level fixed installation.
- 1" exit ferrite magnet compression driver with screw fitting.

- Titanium diaphragm with double sinusoidal roll surround (titanium).
- 40 Wrms (AES standard).
- Copper inductance ring for extended response.
- Ferrofluid cooled.
- Self aligning diaphragm for easy field replacement.
