HK Audio LINEAR 9 118 SUB A
Small and light yet powerful, this direct-radiating subwoofer packs authoritative bass performance into an easy-to-transport housing with a petit footprint. Setting up cardioid configurations is an exercise in convenience with the on-board cardioid filter set – no calculations required. With frequency and phase response tuned to match the 118 Sub BA, it pairs up well with its bigger sibling for both to deliver outstanding performance.
LINEAR 9 is not just a product for professional sound reinforcement – it is a comprehensive solution that sets new standards when it comes to maximum sound pressure level, throw and scalability. There’s also an easy-to-use remote software application, which can be used to control not only the DSP but also the unique DSP Out. This flexible solution with smart features is suitable for the demanding everyday conditions of touring life thanks to the resistant construction and coating of the cabinets.
LINEAR 9 is the new flagship model in the extensive HK Audio LINEAR family. This new class of speaker was developed with the needs and demands of rental companies and event companies in mind, all of whom require a reliable, versatile, future-proof, economical and, at the same time, acoustically and mechanically superior sound tool suitable for many years of daily use.
These requirements are fulfilled in every detail of the LINEAR 9 models: speaker components selected without compromise, precise sound guides specially developed for the series, PU-coated birch multiplex cabinets, generously dimensioned Class D power amplifiers of the latest generation, professional PowerCon power connections and, last but not least, their development and manufacture in our factory in St. Wendel (Germany) make the LINEAR 9 speakers exceptionally powerful and valuable alternatives in their class.
