Martin Audio Blackline F15+ 15” Passive PA Speaker – 400W AES High-Power

Martin Audio Blackline F15+ 15” Passive PA Speaker – 400W AES High-Power Wide-Bandwidth Stage Monitor / FOH System

The Martin Audio Blackline F15+ is a high-performance, compact two-way passive loudspeaker system designed for professional sound reinforcement in demanding environments. Built around a powerful 15” (380mm) LF driver and a 1.4” (35mm) exit compression driver, it delivers wide bandwidth, high output, and excellent clarity across the frequency spectrum.

Its 80° × 50° rotatable constant-directivity horn allows flexible coverage whether used as a front-of-house speaker or as a high-powered stage monitor. The birch plywood enclosure is engineered for durability and acoustic performance, making it suitable for touring, clubs, and fixed installations.

Designed with installation flexibility in mind, the F15+ includes multiple M8 rigging points, a top-hat pole mount, and a multi-angle cabinet, allowing it to be deployed in horizontal, vertical, or wedge monitor configurations. The advanced LF and HF driver design ensures low distortion, improved heat handling, and consistent sound at high output levels.
