Martin Audio MLX, Very high-performance 2x18" Subwoofer
Class-leading output levels are achieved by combining Hybrid® horn/reflex loading with IPAL driver and amplifier technology. Hybrid loading of two ultra-long excursions 18” (460mm) neodymium magnet drivers perfectly balances low-frequency extension with breathtaking chest-thumping bass that has a physical impact. Martin Audio MLX enclosures are designed to be flown or ground-stacked and a combination of forwarding and rear-facing enclosures can be configured as a directional subwoofer array with specific directional properties, including cardioid. Audio settings for the Martin Audio MLX can be controlled either cabinet-by-cabinet or as complete arrays via the VU-NET™ network, with its intuitive graphical interface. Symmetrical rigging enables MLX’s to face backward in flown arrays.
The Martin Audio MLX’s onboard Class D amplifier delivers a total peak output of 8500W. Its lightweight power supply auto-ranges to global mains voltages from 100 to 240V 50/60Hz and Power Factor Correction ensures stable performance independent of mains fluctuations, as well as reducing demands on the mains supply. The amplifier, power supply, and control electronics are housed in a field-replaceable, fan-cooled module that is designed to withstand the varied environmental conditions — such as rain and high ambient temperatures — typically found in live sound applications. The MLX enclosure is made from multi-laminate birch plywood and finished in a hard-wearing, textured black polyurea coating. A rigid perforated steel grille protects the front of the enclosure, while rubber cheeks protect the sides. Interlocking skids protect the top and bottom surfaces and prevent movement when stacked. Up to 15 MLX’s can be flown from an MLA system flybar.
