The CHS-70A driver is a new type of small driver from MarkAudio. While its mechanically similar to the CHR-70 series drivers, its major design features are more advanced.
The main feature of the CHS-70A is its new low-mass thin profile glass-fibre injected chassis (frame). This chassis design has taken 2 years of research and development to produce a highly damped strong frame that makes installation easy. The CHS-70A can be either surface mounted or recessed into a loudspeaker box. The chassis mounting depth is only 3.5mm making it easy fit for either type of installation. The chassis appearance is
high quality, with a professional industry finish that makes the CHS-70A look expensive while it remains affordable.
The CHS-70A features a new shape cap and revised suspensions giving it a wide range with controlled mid response to help reduce “shout”, typical of many small wide band drivers. Vocals on the CHS-70A are clear and natural. Baffle Step Compensation (BSC) is enhanced on the new suspension layout, making this driver more effective in combating box losses in the low range. Other new features include longer gold plated connectors for easier soldering or using clamp type connectors.
The new CHS-70A is an excellent high-end and multi-purpose driver. Its also suitable for many computer, Home Theatre, TV, and commercial A/V applications.

Why are there two different designs to the cone? Two have a indent in the center and the other 2 do not. Curious to what difference this makes on the off axis results at high frequencies

Any new information, impressions on this driver, anybody used it to replace an EL-70 for example ???
We used it in place of a CHR in a dCHR-Ken70. Works fine. I am going to take the 4 we have and try them the empty Thirlmere-R we have and hopefully use them as helper woofers.
