Nexo L18 subwoofer is a compact, horn loaded sub-bass, with high-excursion 18” woofer – capable of 140dB SPL. The L18 is built around a 15 mm custom made bent plywood shell, using poplar veneer for the inside layers and birch of the outside. The result is a plywood with exceptionally good sound quality, a very robust enclosure and a light weight. The band-pass, Horn loaded tuning is done through two computer optimised shaped port guarantee of ultra-low distortion even at very high level. Three large comfortable handles on each side ensure easy manipulation of the L18 in any situation, particularly when used with its dedicated wheel-board and cover. The back plate holds two Speakon® connectors that can be used for both multiple L18 daisy-chaining or to link a P15 speaker. The 18” neodymium transducer with a 4.5” voice coil offers an enormous stiffness and a very high displacement capacity. Together with the very unique cabinet design, they produced a very tight sub-bass sound with a high impact. Just like its companion main speaker P15, the L18 has been developed to precisely match the output power of the NXAMP4x2mk2. Will it fit? HxWxD: 559 x 680 x 775 mm Weight: 50kg
