Status, October 2026: discontinued. Mackie's CR Series lineup now lists only the Gen 3 models (CR3.5 to CR8SBT) and the CR4-X page has been removed, which retailer listings confirm. The Bluetooth CR4-XBT was its sibling in the same range.
What it is
The CR4-X is a pair of 4-inch powered multimedia monitors from Mackie, announced in January 2020 and on sale from March 2020 (Mackie announcement). It was part of the CR-X update to Mackie's CR Series, which added 3-, 4- and 5-inch wired models, Bluetooth XBT versions and the CR8S-XBT subwoofer. The CR4-X itself has no Bluetooth.
One speaker is powered and drives the passive one over the included speaker cable, so only one plugs into the mains (100 to 240 V), through an attached power cord. A rear switch sets whether the powered speaker sits on the left or the right. Its front panel has the on/off and volume knob and a 3.5 mm headphone jack, and plugging in headphones mutes the speakers.
Each wooden cabinet holds a 4-inch polypropylene-coated woofer and a 0.75-inch ferrofluid-cooled silk-dome tweeter behind a waveguide, with a rear port and a 3 kHz crossover. A Class AB amplifier gives 50 W peak. Mackie quotes 65 Hz to 20 kHz at -3 dB and a peak SPL of 100 dB for the pair, and designed the CR8S-XBT subwoofer to add bass to any CR Series monitors.
The inputs are 1/4-inch TRS, balanced or unbalanced, RCA and a 3.5 mm stereo jack. The TRS and RCA inputs are wired together, so only one of them should be connected at a time. Each speaker measures 155 x 225 x 210 mm, and the pair weighs 4.6 kg. The box holds the speaker-to-speaker cable, a 3.5 mm to stereo RCA cable and a 3.5 mm to 3.5 mm cable; isolation pads come only with the larger CR5-X.
