The CHN70 is a Full Range design for use 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. The main features of the CHN70 are:

  • Full Range operation (45Hz to 20kHz in box)
  • Natural sound (near flat response)
  • Long throw power-train design (Mech Xmax = 4mm 1 way)
  • Heavy duty pressed steel frame, damped design
  • Easy surface mounting installation

The cone, coil and suspensions are all-new design. The profile shape is unique to this driver, to give it a neutral musical tone. The frame is made from 0.8mm high quality pressed steel with synthetic damping coating to reduce vibrations and for best environmental protection. The CHNʼs sound character is natural, especially suitable for vocal reproduction. The CHN70 is suitable for sealed and ported box designs from 4 litres to 12 litres volume. Other box designs can also be used.

In a 0.1 to 0.15 cubic foot box (about 4 liters), you should have a 3dB down response at about 119Hz.  Of course there are many other boxes you can use with this speaker.  

In a ported box of 0.2 cubic feet with a 1.5" diameter vent by 4" long (or 1" Ø x 1.5" long), your f3 is about 70Hz.

Small to medium sized speakers are usually lower power designs. The power rating is given in the technical data for each audio driver. For a reliable long service life, please operate your new speakers with care.

For the first 100 hours, operate them at very low volumes. After this period, gradually increase the volume to a normal listening level. If you see the cone of the speakers making large movements, immediately turn the volume down. This will protect the speaker and your human hearing from damage. Factory mechanical defects for a period of 2 year. Excessive hard use (overdriving) and other damage caused during customer use is excluded from our warranty.
