Power & Impact.
Blackline X15

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 clarity.


Symmetrical Multi-Angle Enclosure

Engineered for Excellence.

Rotatable 80° x 50° Horn

The 80° x 50° constant directivity horn is user-rotatable, allowing for both vertical and horizontal mounting. This ensures precise coverage patterns whether deployed as main PA or stage monitor.

Robust Construction

Constructed from durable birch/poplar plywood and finished in textured black paint. The X15 features a screw-free, cloth-backed steel grille for a clean, unobtrusive visual aesthetic suitable for any venue.

Extensive Rigging

Features 19 x M8 threaded inserts for eyebolt suspension and wall brackets, plus a standard pole-mount socket with a removable bung to maintain clean lines in permanent installs.

Stage Monitor Ready

The symmetrical multi-angle cabinet geometry allows the X15 to function perfectly as a high-power floor monitor, delivering clear, punchy sound to artists in a horizontal configuration.
