The M1D-Sub ultracompact subwoofer complements the M1D ultra-compact curvilinear array loudspeaker by extending bandwidth with its operating frequency range of 32 Hz to 180 Hz. Because it produces a prodigious peak SPL of 130 dB at 1 meter from a compact cabinet, the M1D-Sub allows system designers to minimize array size while maximizing system response.
M1D-Sub contains two robust 10-inch cone drivers, each featuring a 2-inch voice coil and a lightweight neodymium magnet structure. Power rating per driver is 400 AES watts*. A fully integrated and self-powered system, the M1D-Sub also incorporates a two-channel class AB/bridged complementary MOSFET amplifier with 450 watts total burst capability. An Intelligent AC power supply selects the correct operating voltage in the range of 90 to 264 V AC at 50 or 60 Hz, allowing international use without manually setting voltage switches. The Intelligent AC supply also performs protective functions to compensate for hostile conditions on the AC mains. These functions protect both the loudspeaker and electronics from erratic AC conditions and increase the lifespan of the loudspeaker. An ultra-low-noise fan is fitted, but cooling is primarily provided by a massive external extruded aluminum heat sink.
M1D-Sub features Meyer Sound’s QuickFly rigging system with rugged, reliable and deceptively simple components. All load stresses are transmitted through the rigging frames and associated hardware, not through the wooden cabinets. The optional QuickFly MG-1D multipurpose grid allows either flying or ground stacking various combinations of M1D and M1D-Sub. Up to 16 M1Ds (or the equivalent weight of M1D and M1D-Sub) with a 7:1 safety factor may be flown, or up to 8 M1Ds or 4 M1D-Subs may be ground stacked. For flying only, the simpler optional MTG-1D will support up to 16 M1Ds (or the equivalent weight of M1D and M1D-Sub) with a 7:1 safety factor.
The M1D-Sub includes Meyer Sound’s RMS monitoring system as standard. RMS allows the full range of operating parameters to be monitored in real time, remotely over a network using a Windows computer.
* Power handling is measured under AES standard conditions: transducer driven continuously for two hours with band-limited noise signal having a 6 dB peak-average ratio.
