HK Audio Linear Sub 1800 A : 18″ Active Subwoofer

LINEAR SUB 1800 A – an 18″ bass reflex subwoofer – is packed full of low end. Unrivaled power, SPL of up to 132 dB and thumping bass (all the way to 38 Hz) make this powered sub the ideal add-on to mid/high units from the LINEAR 3 family when you need just a little more loudness and low end. LINEAR SUB 1800 A can also be used in combination with mid/high units from the LINEAR 5 family, as a bass extension to the Elements Big Base system or as a bass extension for the active 2.1 LUCAS 2K18 system.
