A Sub Designed for the Linear 3 Series, Compatible with All HK Audio Sound Systems
Part of the Linear 3 lineage, the L SUB 1800 A adopts the electronics approach of the L SUB 1500 A with an 18-inch driver for more energy. A dedicated switch optimizes alignment when using four subs to thicken the low end. Despite this positioning, it also integrates very well with Linear 5 systems or as reinforcement for a Lucas 2K18 and an Elements BigBase Single kit.
Who Is It For and What For?
Ideal for DJs, event providers, and live bands seeking a robust subwoofer, the L SUB 1800 A excels with electronic music, outdoor shows, or any application requiring clean, deep, and punchy bass, while remaining easy to deploy in 2.1 setups or multi-sub stacks.
