Whether deployed alongside the LIGNUM-8 or LIGNUM-12 full-range speakers in a high-output system, or as a standalone low-frequency reinforcement solution in a larger distributed audio installation, the LIGNUM-12SUB delivers bass with authority, precision and remarkable fidelity.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHigh-Performance 12\" Transducer\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eAt the heart of the LIGNUM-12SUB is a 12\" woofer featuring a pressed paper fibre cone, ferrite magnet and a substantial 65mm copper wire voice coil — significantly larger than the 38mm coil found in the LIGNUM-8SUB, providing greater thermal capacity, higher power handling and the ability to sustain high output levels over extended periods without degradation. With an exceptional sensitivity of 99dB at 1W\/1m, the LIGNUM-12SUB is among the most acoustically efficient subwoofers in its class, delivering outstanding output levels from professional passive amplification systems whilst keeping energy consumption in proportion. Low total harmonic distortion ensures clean, defined bass reproduction even at the highest output levels, whilst the built-in bass reflex design maximises low-frequency extension and efficiency from the enclosure.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eOmnidirectional Coverage with Wide Frequency Range\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe LIGNUM-12SUB's omnidirectional low-frequency dispersion ensures uniform bass coverage throughout the listening area for seamless integration with any full-range speaker system. Its frequency response extends from 57.3Hz to 360Hz (±3dB) — with the -10dB range reaching as wide as 49Hz to 865Hz — making it a highly versatile low-frequency reinforcement tool that integrates effectively with a broad range of full-range speaker configurations across the LIGNUM range and beyond.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eFlexible Connectivity \u0026amp; Satellite Speaker Support\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe LIGNUM-12SUB provides comprehensive connectivity via both 2-pin safety Euroblock and 4-pole speaker connectors on both input and output sides, enabling straightforward integration with amplifiers, crossovers and full-range speakers, as well as easy loop-through connection for multi-speaker configurations. A dedicated 35mm pole mount socket on the top of the cabinet allows a LIGNUM full-range satellite speaker to be mounted directly above the subwoofer — creating a compact, self-contained satellite and subwoofer system that is both practical and professional in any installation environment.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDurable Construction \u0026amp; Versatile Mounting\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe LIGNUM-12SUB's enclosure is constructed from birch plywood with a sprayed polyurea coating for excellent long-term durability in demanding commercial environments. A reinforced steel grille with acoustic foam and powder-coated finish provides robust driver protection and a clean, professional black finish. Five M8 mounting points offer flexible flying, wall mount and safety anchoring options, whilst VESA 100x100 compatibility (4 x M6) provides structured mounting solutions for permanent installation environments.
