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.

The 2x4ohm LAs418G version has been designed to be driven by Powersoft X series (X4 or X8). This new version presents an increase of 4dB of SPL when it is driven by the Powersoft X Line amplifier while compared with MA6000 driving the normal version, the LAs418G.
