Two-Way Passive
High-Power 15" System


Featuring a powerful 15” (380mm)/3” (75mm) voice coil LF drive unit, and a 1” (25mm) exit HF compression driver with a 1.75” (44mm) polyimide diaphragm for extended high frequency response.
The X15 is constructed from plywood and fitted with a screw-free steel grille, M8 inserts for a wall bracket and eyebolt suspension, plus a pole-mount socket with a removable bung that maintains clean lines in install applications. Finished in black textured paint as standard, the X15 can also be supplied in white or any RAL colour to order.
A full-range passive two-way system, the X15 may be used without a controller. However, the EQ and limiter functions of a controller such as the Martin Audio DX0.5 will maximise its capabilities. When used in conjunction with an X115, X118 or X210 subwoofer, crossover and EQ functions can be performed by the DX0.5.
