Markaudio CHR-120-Champagne 6" Metal Cone Full Range
Overview
Markaudio CHR-120-Champagne 6" Metal Cone Full Range- 202mm- 8 ohm
The CH series continues to make Mark Audio’s cutting-edge engineering accessible at a low price point. Critical technologies including advanced motor designs, reinforced low-loss polymer or sculpted metal baskets, long-stroke suspension and our legendary cone designs offer excellent performance at an affordable level.
The CHR-120 is a brand-new 6-inch (actual frame diameter 7.95") high fidelity multi-purpose high-volume driver design from Markaudio. This new driver has been purposely developed to provide significant bass extension beyond what many similar-sized midbass units can deliver, combined with full-range frequency output. Low enough Q for ported box.

The CHR-120 cone is made from a high-strength, aerospace grade magnesium-alloy designed to cope with high bending stress loads. Based upon our 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.
Use QC250R and QC250B if not soldering your wires directly to the driver tabs.

TL Enclosure
I built a smaller bookshelf version as a 2-way with a 4” woofer and external tweeter that produces a wide soundstage and surprising bass. But getting a similar result with a full-range driver has been… elusive.
Until the CHR-120. I needed to upsize the plan to a 39” tall cabinet, but after some tweaking the result was an extremely articulate, tight and lifelike sound.
Vocals are… stunning. Staging is spot-on realistic, (runs in the back) and the bass is tight, punchy where it should be, and goes down into 30’s.
I’ve listened to songs that I’ve heard literally thousands of times (like Al Green’s ’Let’s Stay Together’ that I’m listening to as I type this) and heard things I’ve never noticed before.
