LINEAR SUB 4000

Powerful and Versatile

L SUB 4000 is the ﬂexible new 18" passive 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 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 80 Hertz.

Innovative and Combinable

The chambers of this double-ventilated band-pass enclosure were

tuned dierently, and optimized for ultra-low signals and kick

drums. L SUB 4000 can be deployed ﬂexibly as the sole subwoofer

for a PA or as a sub-low extension unit.

HK Audio engineers tuned the L SUB 4000’s band-pass enclosure

and the ﬁlter presets to deliver phase-corrected response when

paired with the L SUB 2000. This means the L SUB 4000 can be

added to a legacy system without requiring additional outboard

controllers. To this end, the freely assignable terminals, which are

switchable between the ﬁrst and second pair of NL4 connectors,

give you even more cabling options.
