Product Details

Markaudio CHP-70 Black 4" Full Range Paper Woofer

 

This updated (Gen. 2) CHP-70 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 singer's voice sound very natural, a little warm, pleasing for many hours of listening.

 

The CHP-70 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 are excellent. This driver can fill a room environment with an "easy listening" experience, especially for the 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.

 

Several technical improvements have been done, such as 1 - Improved stiffer frame. 2 - New cap design with a new improved fitting method. 3 - New Japanese designed coil. 4 - New spider for improved bass. The CHP-70 Gen. 2 is an excellent "classic" and "natural" sound driver. The CHP-70 Excursion Arrestor will make a sound when exceeding the driver’s excursion limits.
