Description
The CHR-120 cone is made from a high-strength, aerospace grade magnesium-alloy designed to cope with high bending stress loads. Based upon Markaudio’s renowned shallow profile, wide-dispersion multiform cone concept, the material thickness is carefully balanced to maximise low-frequency load capacity while retaining excellent performance at higher frequencies. The long-stroke suspension and low-distortion motor are designed to provide a low resonant frequency, medium Q and an air volume compliance of around 59 litres. Optimised for use in larger enclosures, the CHR-120 can provide output to some 30Hz and smooth high frequency range extending above 20KHz in a suitable design. Other key features include an “easy install” reinforced polymer frame for both surface and recessed mounting.
The CHR-120 provides custom builders with wide operational flexibility at a surprisingly affordable price, and can be used as a high-performance full-range driver, or as a wide-range midbass. It is ideal for use in high-fidelity, home-theatre, commercial A/V applications, and by suiting a wide range of enclosure types, it continues Markaudio’s reputation for providing qualitative excellence and advanced mechanical engineering at an accessible level.

Wow! Just received 2 off CHR 120 in Grey, the build quality is very high! I’ve been playing around with loud speaker cabinet design for 25 years and I’ve never ever purchased 2 drivers who’s T&S parameters have been measured to within 1% off the published datasheet values! I thought I’d never see this, short off having access to the pick of 1000’s of units (which has never happened). This used to frustrate me as an Engineer. Well I’m not frustrated any more!

Great review Darren, many thanks.

Disse slår ut alt jeg har hatt av høytalere, godt med bass og stemmer høres fantastisk ut. Beste kjøp jeg har gjort.
Translation – These beat out everything I’ve had of speakers, good with bass and voices sounds fantastic. Best purchase I have made.
