Product description

DM-40D-K Black 4" Compact Active Monitor Speaker (pair) 

The DM series speakers deliver balanced, punchy bass sound and they can pump out extra power thanks to the new Class D amplifier and 5-inch woofer in each unit. Flick the switch to change from DJ mode to Production mode and the DSP settings will automatically create the best sound for each application.

Class D amplifier
Each DM series speaker produces pure, balanced bass sound thanks to a new Class D amplifier with 96kHz sampling DSP.

DECO convex diffusers
Another advancement from the DM-40 model comes in the updated design of the DECO convex diffusers which help deliver crystal-clear high frequencies in every direction, so you can enjoy a wide sweet spot and 3D stereo sound wherever you are in the room.

Time alignment
The woofer and tweeter are perfectly aligned so you’ll hear all sound frequencies clearly

Grooved ducts
The grooves on the ducts reduce air friction so bass is tight and punchy, even if you position the speakers against a wall. Plus, the curved front edges provide maximum rigidity and minimum resonance for clean audio at any volume level.

4-inch woofer
The 4-inch woofer creates powerful sound without distorting, even if you pump up the volume.

2-way sound mode – optimized for DJing and music production
There’s no need to decide whether you want a set of monitors that are best for DJing or making music, because the DM series speakers are perfect for both. Just flip the switch to choose either DJ mode or Production mode and the DSP settings will be optimized for the task, leaving you free to concentrate on your mix.

Easy to use with different DJ or production equipment
With RCA and mini jack terminals you can connect different kinds of gear such as DJ controllers and mixers, or the laptop or soundcard you use. Connecting your headphones is simple via the socket on the front panel and the level knob is right in front of you too.
