HK Audio LINEAR 7 118 Sub A 18-inch 2000W Active PA Subwoofer

The LINEAR 7 118 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 7 T 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.

Cardioid in practice
While medium and high frequencies are naturally directional, low frequencies are spherical. This often leads to an unpleasant excess of low bass on and behind the stage. An even more serious issue is that it is becoming increasingly common for event organizers to set precise specifications for sound distribution. In the bass range, this can only be achieved with cardioid technology. The 18" LINEAR 7 Subwoofer therefore meets all the requirements for quickly and easily implementing effective cardioid setups, both mechanically and with the available filter sets.
