Overview
MarkAudio CHR-90 Gold 5" Metal Cone Full Range- 151 mm- 8 ohm
MarkAudio CHR-90 Gold 5" Metal Cone Full Range- 151 mm- 8 ohm
The CHR is an affordable all-new 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 CHR90 is highly capable.
Most Markaudio drivers have a purpose designed frequency lift in the lower ranges (typically 100Hz to 500Hz) to compensate for baffle step losses. The CHR90 is useful to these applications where end-users and loudspeaker makers need a wider choice on frequency cross-over point selection.
The CHR90 chassis is an all-new design, dedicated to this driver. All moving parts (powertrain) are new and custom made for this driver. Much work has been done to make the CHR90 a versatile driver and extend the well-known performance characteristics of Markaudio’s products.
Outer Diameter: 151 mm (5.95")
Mounting hole to mounting hole: 139 mm
Cone diameter: 90 mm
Solder Tab: 0.25" or 6mm (quick connects)
Fun linear quadrupole cabinet design here!

- Centre-channel has two forward-facing slot-vents; alignment is quite well damped.
- Sealed standmount is a Butterworth (lowest possible flat tuning) alignment, assuming a voltage-source amplifier and normal connection & wire resistance. It won't get very low, but should do a decent job in smaller spaces, or as a satellite / surround speakers.
- Sealed floorstander is a Bessel (maximally flat group delay) alignment, assuming a voltage-source amplifier & normal connection & wire resistance. This one is designed to be used close to a wall or in corners; the Bessel alignment is well-damped so it suits being used near walls.
