Martin Audio S12+

Martin Audio S12+ Blackline from £639

The Martin Audio S12+ Blackline is an extremely compact sub-bass system.

It has been designed for use with the F8+ and F10+ full-range loudspeakers in situations where extended low frequency output and increased system headroom are required. When used with a Martin Audio F8+ or F10+, it will extend the response of the complete system to below 50Hz.

The Martin Audio S12+ is provided with a top hat fitting that can be used to pole mount an F8+ or F10+ 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 S12+ high power speaker system or any other product from the Blackline range.
