The CHP-90 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 CHP-90 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 48 Hz, VAS is +20 Litres and SPL 89.2 dB. Useable frequency range (depending on box design) is from 37 Hz to 28 kHz rated at +89 dB in many applications. The frequency response curve is near flat, making the CHP-90 ideal for purist applications. The central mid-range is benign, near flat response, from 1 kHz to 6 kHz giving end-users and custom builders the potential to use the CHP-90 as a mid-field driver in larger multiway applications, useful for balancing out larger radiated surface outputs from big bass units .
The CHP-90 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 100 Hz to 500 Hz) to compensate for baffle step losses. The CHP-90 is useful to these applications where end-users and loudspeaker makers need a wider choice on frequency cross-over point selection. The CHP-90 shares the custom, modified-ABS chassis design with the CHP-90. All moving parts (powertrain) are new and custom made for this driver.
Much work has been done to make the CHP-90 a versatile driver and extend the well-known performance characteristics of Markaudio’s products .
