The HK Audio Linear 9 118 Sub BA is a high-performance 18-inch powered subwoofer designed for professional sound systems that require both impressive output and precise bass reproduction. This active dual vented bandpass subwoofer is built to provide high sound pressure levels while maintaining a low cutoff frequency, ensuring exceptional bass response and clarity. The subwoofer is ideal for use in a variety of settings, including live sound reinforcement and large-scale events, and is fully compatible with the LINEAR 9 Mid/High models, making it an integral component of the LINEAR 9 series.
Equipped with a robust 18-inch bass driver with a 4-inch voice coil, the Linear 9 118 Sub BA is driven by a powerful 1100W Class D amplifier. This combination delivers a peak SPL of 136 dB, offering deep, impactful bass that cuts through even the most demanding sound environments. The dual vented bandpass design allows for enhanced efficiency and low-frequency extension, making this subwoofer a perfect match for mid/high units that require extended bass support. The subwoofer is engineered to handle the full range of bass frequencies, from 31 Hz to the crossover point, ensuring a dynamic and powerful low-end performance.
At the heart of the LINEAR 9 118 Sub BA is its integrated DSP (Digital Signal Processing) platform, which can be controlled via the HK Audio DSP CONTROL software. This software offers full access to a 10-band parametric EQ, delay functions, and limiting capabilities, allowing users to fine-tune the subwoofer's performance to suit specific acoustic needs. With four selectable DSP presets, including the standard "Front," "Cardioid 1:1," and "Cardioid 2:1" configurations, users can quickly and easily implement effective cardioid setups to control bass distribution and reduce low-frequency buildup on stage. The fourth preset allows users to create their own custom settings for maximum flexibility.
The subwoofer's high-resolution AD/DA converters, operating at a 96 kHz sample rate, ensure low system latency of less than 2.6 ms, providing precise timing and synchronization in complex audio setups. The LINEAR 9 118 Sub BA also features a DSP-Out port, enabling users to integrate non-network-compatible loudspeakers into the system and extend its capabilities. With professional-grade PowerCon and EtherCon connections, the subwoofer is ready for any high-end audio setup and provides reliable connectivity for both power and data transmission.
Designed for durability, the LINEAR 9 118 Sub BA features a robust birch multiplex enclosure coated with a resistant PU finish. This ensures that the subwoofer is protected from the elements and is ready for the rigors of transport and outdoor use. The unit also features multiple carrying handles for easy maneuvering and transportation, and the sturdy construction ensures longevity and reliability, even under challenging conditions.
With a pair of M20 tripod threads for mounting mid/high units and a range of rigging options, the LINEAR 9 118 Sub BA is designed to integrate seamlessly into a wide variety of system configurations. Whether used as part of a larger cluster setup or as a standalone subwoofer, this powerful bass unit delivers consistent, high-quality bass reproduction, ensuring that sound engineers can achieve the best possible performance in any environment.
