This is a great little cheap driver, there are loads of boxes available out there for it, we like the Frugal Horn 3 and the Pensil designs but take a look through all of them.

This updated (Gen. 2) CHP-70A driver is designed to make a semi-vintage classic sound, similar to the smaller full range driver designs from the 1950ʼs. Its middle-high range output has been made to “roll-off” from 7-kHz up. This helps to keep the high range sounding smooth and warm. This driver makes the singers voice sound very natural, a little warm, pleasing for many hours of listening.

The CHP-70A Gen. 2 will assist in the control of sharp or hard sounding compressed music (digital) . This CHP delivers a tone that appeals to classic music enthusiasts using smaller amplifiers. The off-axis and sound-spread of the CHP-70 is excellent. This driver is capable of filling a room environment with an “easy listening” experience, especially for human voice. The bass response from the CHP-70 Gen. 2 in a properly tuned box is excellent for this smaller sized driver. Typically, in a Bass-Reflex or Vented box, lower responses close to 40Hz can be obtained.

Many technical improvements has been done. 1 – Improved stiffer frame. 2 – New cap design with new improved fitting method. 3 – New Japanese deigned coil. 4 – New spider for improved bass. 5 – Two color choice (natural paper and black paper cones)

The CHP-70A Gen. 2 is an excellent “classic” and “natural” sound driver.

The CHP-70A Excursion Arrestor will make a sound when exceeding the drivers excursion limits.
