HK Audio L9-118SBA

The LINEAR 9 118 Sub BA is a powerful 18" dual vented bandpass subwoofer. The generous size of the cabinet allows for an exceptionally high sound pressure level with a low cut-off frequency at the same time. This makes this subwoofer not only a perfect partner for powerful full-range speakers, but also an ideal sub low extension for the direct-radiating LINEAR 9 118 Sub A. Thanks to the integrated presets, cardioid setups can be implemented quickly and easily. The LINEAR 9 118 Sub BA is compatible with all LINEAR 9 Mid/High models.
