Description
3 MU12M is a professional and compact monitor system, it is suitable for all the demanding monitor applications. Adopt ed Neodymium compression driver integrate 3″ polymer diaphragm to assure the big power output and delivery natural sound performance, the dispersion is 45 x45. 12″ Neodymium woofer integrates 3″ voice coil and latest improved magnet circuit&short-circuit ring to achieve the low distortion and Max. clarity under high SPL. Very compact design, lightweight, and very powerful. Perfect protection circuit design makes sure the system works smoothly and safely. MU12M produces 121dB SPL continuously and 80-16kHz frequency response, suitable for different applications from small to large scale, including speech and full-range applications. MU12M adopts the ergonomic cabinet design. Large arc cabinets effectively reduce the collision harm, and the round handle design makes the carrying very balanced during the transport. NL4 connectors are available on both sides to optimize the system wiring. The cabinet is made of 15mm Russian birch plywood so it had vancedenviron mental protection. polyurethane-based painting. The steel grille is coated with powder to provide strong ultra- Weatherability.

Speaker testing method
-
Frequency response
Use Pink noise to test the speaker in the anechoic room, adjust the level to make the speaker work at its rated impedance and the power output is 1W, then test the frequency response 1m away from the speaker. -
Sensitivity
Use full range Pink noise which was modified by EQ curve to test the speaker in the anechoic room, enlarge the signal to make the speaker work at its rated impedance and the power output is 1W, then test the sensitivity 1m away from the speaker. -
MAX.SPL
Use full range Pink noise which was modified by EQ curve to test the speaker in the anechoic room, enlarge the signal to make the speaker work at its instant power output level, then test the SPL 1m away from the speaker. -
Rated Power
Use the pink noise according to IEC#268-5 to test the speaker, and enlarge the signal for a continuous 100hours, the rated power is the power when the speaker will not incur hot damage or mechanics damage.
