Advanced design for higher quality soundEach speaker in the DM series includes a Class D amplifier with a 96 kHz sampling DSP to produce a pure and balanced bass sound. You can also enjoy a wide sweet spot and 3D stereo sound from anywhere in the room thanks to the DECO convex diffusers, which feature an advanced design compared to the original DM-40 speakers and help deliver clear high frequencies in all directions. When you need to turn up the volume, the woofer creates additional power and is perfectly aligned with the tweeter so that you can hear all sound frequencies clearly. The same slots in the DM-40 ports reduce air friction so that the bass is firm and powerful, even if you place the speakers against a wall. In addition, the curved front edges provide maximum rigidity and minimum resonance for clean audio at any volume level. Bi-directional sound mode optimized for DJing and music productionThere is no need to decide whether you want a set of monitors that are better for DJing or producing music, because the speakers in the DM series are perfect for both. Simply move the switch to choose DJ mode or Production mode, and the DSP settings will be optimized for the task, leaving you free to focus on your mix. Bluetooth® connectivityThe Bluetooth® technology included in the DM-50D-BT and DM-40D-BT models allows you to easily pair your smartphone, mobile device, or PC/Mac and play high-quality tracks wirelessly. Easy to use with different DJs or production equipment.With RCA and mini jack terminals, you can connect different types of equipment, such as DJ controllers, mixers, and the laptop or built-in sound card you use to produce your own music. The DM-50D-BT and DM-50D models also feature a TRS input for even greater compatibility. Connecting and disconnecting your headphones is easy via the jack on the front panel, and there is no need to have the back of the speakers within reach to adjust the volume because the level control is also right in front of you. Smart design, available in 2 colorsGive your setup an elegant and professional look by choosing between 2 different colors. The finish of the black speakers in the DM series pairs perfectly with classic DJ equipment, while the white models can better complement the interior design of your home.
