The black DM-40BT Bluetooth, Active 4″ Desktop Monitor Speakers from Pioneer DJ are a Bluetooth version of the popular DM-40 active monitor speakers. They are designed to accommodate smartphones, iPads, and other Bluetooth devices, but can also be used with cables using the built-in RCA and stereo mini-jack inputs on the rear panel.
The class-AB amplifier outputs 2 x 21W of power at 4 Ohms. The 4″ fiberglass woofers deliver a natural, punchy bass, and the 3/4″ soft-dome tweeters deliver well-balanced high frequencies. A stereo mini-jack headphone output with a speaker-volume knob are built into the front panel of the speaker.
