The M2 is a 2-way high performance stage monitor, with a peak sound pressure level of 143 dB. Its design uses a low height cabinet, achieves a constant directivity of 45° x 60° > 600 Hz and significantly raises the feedback stability margin. Together with the cabinets baffle angle of 40° (to floor), the dispersion performance offers a realistic artist listening area starting directly above the cabinet and reaching quite far upstage. The result is a loudspeaker system with remarkable vocal presence, clarity and neutral, balanced sound. The M2 cabinet is constructed from marine plywood, incorporates handles and has an impact resistant paint finish. Two fittings, which accept ball-lock shackle pins, are located on each side of the cabinet allowing quick and flexible rigging.
The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. The M2 monitor must be driven in 2-Way active mode, requiring two amplifier channels. The d&b D80 and 30D amplifiers are recommended to drive the M2.

The 2-active stage monitor shall consist of two 12" LF driver and a 1.4"exit HF compression driver with a compact but strong neodymium magnet assembly operating into a very low distortion waveguide oriented horn, optimized for monitor applications.
The cabinet shall be constructed from marine plywood with an impact resistant paint finish. The front of the loudspeaker cabinet shall be fitted with a rigid metal grill backed with a replaceable acoustically transparent foam. Each side panel shall incorporate a handle while two runners shall be recessed in the bottom panel to prevent cabinet movement and protect the bottom panel against scratching.
In addition two sockets which accept a compatibel flying pin 10 mm shall be located on both side panels of the cabinet allowing quick and flexible rigging.
The cabinet shall be fitted with NLT4 F/M connectors. NL4, EP5 or NL8 connectors shall be available upon request.
The loudspeaker shall only be operated by a dedicated, compatible controller amplifier.
The power handling capacity of the LF drivers shall be 500 W RMS and 2000 W peak (10 ms) while the power handling capacity of the HF driver shall be 50 W RMS and 200 W peak (10 ms). The frequency response (–5 dB) measured on axis shall be 57 Hz to 17 kHz with a maximum sound pressure of at least 143 dB. The nominal 45° horizontal dispersion angle shall be maintained from 800 Hz - 10 kHz.
The dimensions (W x H x D) shall not exceed 680 x 419 x 560 mm (26.77" x 16.5" x 22.05") and shall weigh no more than 38 kg (83 lb).
The loudspeaker shall be the M2 by d&b audiotechnik GmbH.
