SUBLINE 218SA

The SUBLINE 218SA is a high-performance processed active subwoofer delivering 1200 watts RMS and a maximum sound pressure level of 140dB. Engineered with a bass-reflex design, it features two 460mm high-excursion woofers with 75mm voice coils, custom-built by B&C for FBT. Its frequency response ranges from 30Hz to 120Hz, ensuring powerful low-frequency reproduction. The SUBLINE 218SA is driven by a Class D amplifier with a switch-mode power supply and incorporates a digital signal processor offering six presets, three EQ modes, two low-pass filter settings, and a six-position digital delay. The rear panel includes stereo XLR inputs and outputs, volume control, preset selector, phase switch, delay adjustment, and LED indicators. Constructed from 18mm Baltic birch plywood with a durable coating, it is fitted with ergonomic aluminium handles, dual M20 pole mount threads, and supports optional wheels. When combined with the MUSE 210LA active line array, the SUBLINE 218SA extends low-frequency output for larger sound reinforcement applications.
