Housing two long excursion and very high power 18″ drivers, this Subwoofer has been designed to offer ultra-low frequencies at a very high SPL delivering magnificent precision and punch at incredible pressure levels. The cabinet volume with optimized port tuning – featuring extremely high peak-to peak excursion capability – is capable of delivering true sub performance down to 24Hz at -10dB. Providing low frequency resolution and a maximum SPL of 143.8dB in a 90kg, front loaded, bass reflex enclosure and measuring 516mm x 920mm x 1030mm (HxDxW), the subwoofer incorporates eight handles. Housed within a multi-laminate birch plywood enclosure and finished in textured black semi-matte coating, the LAs418G can be deployed in either standard or cardioid configuration using the parallel wired Neutrik NL4 conector on the front of the Subwoofer.
