SX118 - Overview

Compact, Direct Radiating Subwoofer!

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 SX118 has a pair of NL4 connectors on the rear panel. These are wired in parallel and whilst one is nominally labelled `INPUT' and the other as `LINK', connection in and out can be made to either connector. Connection to the drive unit(s) is made to pins 1+/-. There is no internal connection to pins 2+/- although these are linked together so can be used for example to carry a mid/top signal and connected to a full range system using a cable wired with reverse connections (pins 2 to pins 1).

Please note! 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. (items sold separately)
