HK Audio LINEAR 9 118 Sub A 18-inch Active PA Subwoofer

The LINEAR 9 118 Sub A is a network-compatible, active bass reflex subwoofer. Its bass reflex construction allows for compact dimensions. Thanks to a weight of just 42 kilograms, it is extremely easy to transport. A powerful, precise bass reproduction makes this active bass the ideal complement to the LINEAR 9 mid/high units.

What’s more, it meets all the requirements for quickly and easily implementing effective cardioid setups, both mechanically and with the available filter sets. Thanks to its stereo preamplifier, it is also ideal for use in 2.1 systems.

Four DSP presets can be selected directly on the subwoofer without a PC connected. In addition to three standards (Front, Cardioid 1:1 and Cardioid 2:1), a fourth user-designed preset can also be accessed.

The robust birch multiplex enclosure with resistant PU coating protects the LINEAR 9 118 Sub A not only from wind and the elements but also during transport from the storage to the venue and back again. All LINEAR 9 models are manufactured in Germany.
