HK Audio Linear 9 118 Sub A 1100W Active 18 Inch Subwoofer

The LINEAR 9 118 Sub A is a true powerhouse. Its bass-reflex construction allows for compact dimensions, and weighing in at just 42 kilograms, it is extremely easy to transport. A powerful punch, precise playback and impressive low frequency performance make this active bass the ideal complement to the 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.
