Name: Blackline X15
Rating: 4.7 (23 reviews)

The Blackline X15 is a very high-power, passive two-way system designed for professional portable applications and installations that demand the ultimate in sonic performance from a single enclosure. With an accurately-defined 80° x 50° coverage pattern, it combines very high output capability with exceptional sonic performance and impact.

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.

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 DX0.4 or DX0.6 will maximise its capabilities and provide crossover functions when used with a subwoofer such as the X115, X118 or X210.

Architectural Specs

Martin Audio Blackline X15

The loudspeaker shall be a passive, two-way system. Its transducers shall consist of a reflex-loaded 15” low frequency driver and a 1.7” diaphragm/1” exit compression driver mounted on a high frequency horn which shall be user-rotatable to enable vertical or horizontal orientation of the enclosure.

Horizontal dispersion shall be 80° and vertical dispersion shall be 50°. The on-axis frequency response shall be 55Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 131dB peak calculated at 1 metre. Power handling shall be 400W AES, 1600W peak. Rated impedance shall be 8 ohms.

The rear connector panel shall be fitted with two NL4 type connectors. Low and high frequency sections shall be integrated by an internal 2.2kHz passive network. For optimal performance the loudspeaker shall be operated in conjunction with a dedicated electronic controller.

The symmetrical, multi-angle enclosure shall be made from plywood and finished with a black textured paint. The enclosure shall be fitted with a pole-mount socket and M8 threaded inserts to accommodate eyebolt suspension and a wall bracket. The drivers shall be protected by a perforated steel grille with scrim cloth backing.

Dimensions (W x H x D) shall be 427mm x 690mm x 419mm (16.8in x 27.2in x 16.5in). Weight shall be 24kg (52.9lbs).

The loudspeaker shall be the Martin Audio Blackline X15.
