HK Audio LINEAR SUB 1800 A 1x18" Active Bass Reflex Subwoofer, 1200W Power

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.
