Martin Brother - Blackline S15 500W
The S15 and S18 sub-bass systems can be used in combination with the F12 and F15 to extend and improve the low-frequency output power. The S15 sub-bass produces a low, dry sound thanks to a 380mm driver, while the S18 sub-bass, thanks to a 460mm driver, offers a very low, deep sound. Both drivers have a 101mm high-temperature voice coil , and the cabinets have large reflex chords to reduce air noise. Each sub-bass system can operate in passive mode, through switchable internal passive crossover, or in active mode, through the use of the M3 contoller. Both the S15 and S18 systems have an attachment on the top for installation of an F12 or F15 speaker.
