LINEAR SUBS are system subwoofers that work perfectly with the LINEAR 3 and LINEAR 5 mid/high units.
The system subwoofers all have a stereo input, so in addition to half-stack or full-stack applications, they can also be used as a 2.1 system or mono-summing sub-cluster.

We recommend the following combinations to achieve the ideal ratio between the mid/high unit and the subwoofer:
LINEAR SUB 1500 A and LINEAR SUB 1800 A with the LINEAR 3 mid/high units,
LINEAR SUB 1200 A and LINEAR SUB 2000 A with the LINEAR 5 active mid/high units and
LINEAR SUB 4000 A with the LINEAR 5 LTS A powerhouse.

The two 10″ woofers deliver fast and concrete bass with plenty of punch and low bass down to around 38 Hz.
