Description
The SX118 is a compact, high performance subwoofer that extends the low frequency operating range of the system to 47Hz and provides exceptional low frequency output for such a compact enclosure.
SX118 features a long-excursion 18” (460mm)/4” (100 mm) voice coil driver with a water-resistant cone and triple roll surround in a compact reflex enclosure.
The design of the 18” driver maximises output while minimising power compression and distortion, and the four reflex ports have a large frontal area to reduce turbulent air noise at very high levels. The enclosure is constructed from multi-laminate birch ply, finished with a durable polyurea coating and equipped with a Zintec grille, twin grab handles, skids, flying inserts for installation and a threaded pole socket for pole-mounting point source loudspeakers or up to 4 WPM enclosures as a simple plug-and-play system.
The product is supplied as standard without cabinet wheels, but they are available as an accessory.
By adding the input board cover accessory, SX118 is fully weather resistant and suitable for permanent outdoor usage.
