HK Audio LINEAR 7 118 Sub A Subwoofer - Each - Black

The LINEAR 7 118 Sub A is an extremely powerful yet compact 18-inch subwoofer. Equipped with all the features of the network-compatible LINEAR 7 Series, it delivers phenomenal low-frequency performance in numerous applications.

THE LATEST IN AUDIO TECHNOLOGY

LINEAR 7 is intentionally based on the look and the proven robust mechanics of the LINEAR 5 series, with specific enhancements to the cabinet details. Both technically and acoustically, the LINEAR 7 speaker family represents a completely new development. The latest generation of high-performance speakers and drivers, specially designed horns, high-impulse Pascal Class-D power amplifiers, FIR filtering and the latest, exceptionally high-performance DSP platform with high-resolution converters all make the LINEAR 7 family an acoustically precise tool for demanding applications

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.

DSP CONTROL SOFTWARE

Extended remote controlling
Until recently, only the large touring system price category made it possible to control every mid/high unit, every bass and every stage monitor centrally from the FoH position. Now, with the LINEAR 7 range, this modern and highly efficient workflow can also be achieved in top-range professional point sound sources. Every single LINEAR 7 speaker on the network can be accessed centrally via Mac or PC, and its volume, EQ, limiting, delay and polarity can be controlled in detail.
