Description

The CHN-719 is a full-range design that is used in many audio applications. Designed by Mark Fenlon and Evan Yu for use by audio end-users who want a high-performance driver at a lower cost.
1 – Operating range from 40Hz to 20kHz (depending on box designs).
2 – Natural sound (near flat response).
3 – Long throw power-train design (Xmax +/- 4.3mm).
4 – Heavy-duty pressed steel frame, damped design.
5 – Easy surface mounting installation.
6 – Double magnet system for optimized flux density and damping.
7 – Copper-capped pole piece for reduced distortion and more linear impedance load.
The cone, coil, and suspensions are all-new designs. The frame is made from 0.7mm high-quality pressed steel with a synthetic damping coating to reduce vibrations and ensure the best environmental protection.
The high compliance suspension and powerful magnet CMS1.3mm/N create the CHN’s sound character, which is natural and especially suitable for vocal reproduction.
The CHN719 is suitable for sealed and ported box designs with volumes from 3 to 12 liters; other box designs can also be used.
