Description
Mark Audio CHN-40
This driver is boxed and sold in pairs.
These are the drivers the community have been asking for for years. Small enough to do a close enough centre to centre for line arrays. Well here it is finally!
The CHN40 has a gentle rise into the low and high frequency response, as seen in some of our more expensive drive units, to enhance speaker box off-axis positioning flexibility. The sound presentation is forgiving, without glare, and the Thiele / Small parameters, with a generous 3.5mm (1-way) Xmax are balanced for ease of use.
The low-mass voice coil, suspension and shallow profile magnesium alloy cone are custom designs for the CHN40. The pressed steel frame is designed to be very open and allow airflow to be as free as possible to the rear of the cone. Response extends from resonance to beyond 25KHz, and the impedance rise at higher frequencies is only modest, due to the careful motor design.
The CHN40, like the larger drivers in this series is versatile, easy to install, making it suitable for a wide variety of applications.
