Martin Audio Blackline Q15
Two-Way Passive
High-Power 15" System
Blackline Q15 is a significant upgrade over its predecessor, delivering enhanced performance and wider coverage, and features a die-cast aluminium chassis for improved thermal conductivity and more efficient motor cooling.
A passive two-way system, Q15 is designed for professional portable applications and installations that demand the ultimate in sonic performance from a single enclosure.
Description
Capable of delivering a peak SPL of 133dB (139dB with crest factor 4), Blackline Q15 features a powerful 15” (380mm) LF driver with a 4” (102mm) voice coil and a 1.4” (35mm) exit HF compression driver with a 3” (75mm) dome. Its Differential Dispersion horn ensures wide and consistent coverage and can be easily rotated for horizontal or vertical orientation, depending on deployment requirements.
Q15 is built from robust plywood and finished in durable black paint. It has a screw-tight steel grille, M8 inserts for wall bracket, yoke or eyebolt suspension, and a pole-mount socket with a removable cover to maintain clean lines for installation applications.
This full-range, passive two-way system is recommended to be used with a processor and amplifier, or a combined amplifier-processor unit, such as a DX processor and VIA amplifier, or an iKON combined amplifier and processor.
