L SUB 4000
L SUB 4000 is the flexible new 18” subwoofer from HK Audio. Compatible with all LINEAR 5 fullrange speakers and mid/high units, its powerful low end – ranging from 30 to 100 Hertz – is totally and powerfully impressive. L SUB 4000 A can also serve as a sub-low add-on to LINEAR SUB 2000 to beef up the bottom end in the range of 30 to, for example, 70 Hertz (optional frequency separation). Filter presets are available for Lab.gruppen PLM 12K44 & IPD controllers.
