Martin Audio Blackline Q44 Passive 4 x 4" PA Speaker - White

Q44 is an ideal solution for rental houses seeking elegant voice reinforcement with extended bandwidth and refined musicality, while installers benefit from its versatile mounting options. It can operate as a stand-alone system or be supplemented by Blackline Q210 subwoofer, making it equally suited to performance venues, corporate events and worship spaces.

Q44 features four 4” (100mm) LF drivers with 1.5” (38mm) voice coils and a 1” (25mm) exit HF compression driver with a 1” (25mm) dome. A Differential Dispersion horn ensures wide, consistent coverage.

Constructed from durable plywood, Q44 is fitted with a screw-tight steel grille and includes M8 inserts for wall brackets, yokes, and eyebolt suspension. A pole-mount socket with a removable cover maintains clean lines for installation applications. It is finished in hard-wearing black or white paint.

Engineered for clarity and control, Q44 integrates seamlessly into larger systems or functions as a standalone solution where aesthetics and performance are equally important.

Q44 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.
