Full Range Speaker PHONIC-CHP90 MICA

 

The PHONIC CHP-90 MICA is a 90mm, multi-purpose full-range driver featuring a hybrid paper, mica, and glass-fiber cone. It delivers linear response up to 28,000 Hz, 40W RMS power handling, and 91.73 dB sensitivity, making it ideal for purist point-source or multi-way speaker builds

 

• 90mm cone with paper, mica, glass fiber materials
• Operating range to 28KHz –very linear response
• Long stroke suspension with progressive-rate spider

 

The CHP90 MICA is an attractive Full-Range multi-purpose drive unit suitable for use in variety of medium size loudspeakers applications, or as part of a multiway system. For single full-range point-source purist applications, the CHP90 MICA is highly capable. The cone is formed from paper, mica and fibreglass materials creating high stability in the emitting surface across the usable frequency range .

F Zero is 48Hz, VAS is +20 Litres and SPL 89.2 dB. Useable frequency range (depending on box design) is from 37Hz to 28KHz rated at +89dB in many applications. The frequency response curve is near flat, making the CHP90 MICA ideal for purist applications. The central mid-range is benign, near flat response, from 1KHz to 6KHz giving end-users and custom builders the potential to use the CHP90 MICA as a mid-field driver in larger multiway applications, useful for balancing out larger radiated surface outputs from big bass units.

The CHP90 MICA also has potential for use in 2 way applications as a bass-mid driver. Most Markaudio drivers have a purpose designed frequency lift in the lower ranges (typically 100Hz to 500Hz) to compensate for baffle step losses. The CHP90 MICA is useful to these applications where end-users and loudspeaker makers need a wider choice on frequency cross-over point selection. The CHP90 MICA shares the custom, modified-ABS chassis design with the CHR90. All moving parts (powertrain) are new and custom made for this driver.

Much work has been done to make the CHP90 MICA a versatile driver and extend the well-known performance characteristics of Markaudio’s products.
