Meyer Sound M1D-Sub Amplified Line Array Subwoofer
Meyer Sound M1D-Sub Amplified Line Array Subwoofer
The M1D-Sub ultra-compact subwoofer complements the M1D ultra-compact curvilinear array loudspeaker by extending bandwidth with its operating frequency range of 32 Hz to 180 Hz and substantially increasing overall system headroom. 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. A variety of QuickFly rigging options allows the M1D-Sub to be flown above, below or within an array, or placed at the base of a ground-stacked array. Although it is intended primarily as a companion subwoofer to the M1D, it is perfectly suited to general use where powerful low frequency augmentation is desired.
Features:
- Extremely compact and lightweight
- High power-to-size ratio for maximum installation flexibility
- Exceptional fidelity and peak capability assure clean, high-impact lows
- QuickFly rigging system simplifies use in flown or ground-stacked arrays
- Seamless integration with M1D loudspeakers
