The B18 is a compact, high performance subwoofer for use with the FX12 or FX15. It extends the low frequency operating range of the combined system to 40Hz and provides exceptional low frequency impact. It features a long-excursion 18” (460mm)/4” (100 mm) voice coil driver with a water-resistant cone and triple roll surround in a compact reflex enclosure.

The design of the 18” driver maximises output while minimising power compression and distortion, and the four reflex ports have a large frontal area to reduce turbulent air noise at very high levels.
The B18 enclosure is constructed from multi-laminate birch ply and finished in textured black paint. A perforated steel grille protects the driver and is pre-curved to withstand physical damage.
When used with a Blackline 3 FX12 or FX15 coaxial system, crossover and EQ functions can be performed by the Martin Audio DX1.5 and DX2 system controllers, or by an MA Series amplifier with onboard DSP option.
