DJs, producers, and musicians in search of a small, desktop monitoring system with Bluetooth streaming will be impressed with the Pioneer DJ DM-40D-BT, a pair of black, active, two-way monitors designed for wide-range music applications, well suited for DJ monitoring and music production in the studio or at home.

This highly flexible monitoring system features a sound mode, which switches between DJ mode for a punchy sound suited for DJ applications and Production mode, which provides a flat frequency response that accurately reproduces the input sound. The integrated Bluetooth receiver allows you to stream audio from your smartphone, tablet, or Windows/Mac computer.

4" Fiberglass Woofer    0.75" Soft Dome Tweeter    Built-In Bluetooth for Audio Streaming    96 kHz DSP, DJ/Production Switch    19W Class D Amplifier    Front Diffusers + Bass Reflex Ducts    3.5mm and RCA Inputs    Headphone Output with Volume Control    Includes Bottom Cushions    Includes 3.5mm to RCA Cable

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

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.

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.

The Bluetooth technology included in the DM-40D-BT enables you to easily pair your smartphone, mobile device, or PC / Mac and play high-quality tracks wirelessly.
