Mark Audio, CHP-70A-NP
$36.00
CHP-70A-P, Gen. 2 Full Range audio driver 4″ Natural Paper Cone
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 singers 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 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.

Ken Rhodes –
I built the Mark Audio recommended enclosure for these and use them with no filter/crossover. They do excel in some areas and the build was very strait forward. They are my current listening speakers sitting on top of some 10 in subwoofers. This combination works very well for simple music tracks and they are very intelligible for TV use.

I used these in one of the Markaudio bass reflex cabinets on the website. Made it with baltic birch plywood and a thick polyurethane on top. Beautiful look. The paper is almost the same color as the wood. Sound wise they are great if you dont expect a lot of bass. But that is to be expected from a small full range. But it DEFINITELY needs baffle step compensation. Will be buying more sometime in the future.
