Status, October 2026: discontinued. Mackie's CR3-X page now leads to its third-generation CR Series, launched in October 2024, where the 3.5-inch CR3.5 takes its place.
What it is
The CR3-X is a pair of 3-inch multimedia monitors from Mackie, announced in January 2020 with the rest of the CR-X series and on sale from March 2020 (Mackie announcement). It sat at the small end of a range that also included the CR4-X and the CR5-X. The CR3-XBT is the same size with Bluetooth added; the CR3-X is wired only.
One speaker holds a 50 W peak Class AB amplifier for both and feeds the passive partner through spring-clip terminals and the included speaker cable. A rear switch sets whether the powered speaker sits on the left or the right. Each cabinet is solid MDF with a black vinyl wrap, a brushed-metal front and a rear port, and holds a 3-inch polypropylene-coated woofer and a 0.75-inch silk-dome tweeter crossed over at 3 kHz. Mackie rates the pair at 80 Hz to 20 kHz (-3 dB) and 97 dB peak SPL.
The rear panel takes 1/4" TRS and RCA inputs, which are wired together, so only one source connects at a time, plus a 1/8" stereo input for a phone or laptop. The front has the volume knob, which also switches the speakers on and off, and a 1/8" headphone jack that mutes the speakers.
Each speaker measures 206 x 140 x 180 mm (H x W x D), and the pair weighs 3.5 kg. The box holds a 1/8" to stereo RCA cable, a 1/8" to 1/8" cable and the speaker cable; the CR-X owner's manual covers setup. Mackie's CR8S-XBT subwoofer was sold separately.
