Martin Audio S15+

Martin Audio S15+ Blackline from £869

The Martin Audio S15+ Blackline speaker is a compact sub-bass system and has been designed to be used with the Martin Audio F12+ or F15+ full-range systems to extend and increase the total low frequency output power.

The S15+ definitely provides good bass punch from a new, long-excursion, 15” (380mm)/4” (100mm) voice coil driver with a water resistant cone and triple roll surround.

The Martin Audio S15+ is provided with a top hat fitting that can be used to pole mount an F10+ or F12+ above the enclosure.


Please call us at Old Barn Audio on 01892 752246 if you have any questions, or would like to buy either a Martin Audio S15+ high power speaker system or any other product from the Blackline range.
