Church Use: Loudspeaker and Subwoofer System


The Alto Black series is a brand new line of high quality active PA speakers and subwoofers designed for power, portability, and control. We had the opportunity to review a set of two 15” loudspeakers and an 18” subwoofer and found the whole system to be quite an impressive little rig.


Features: The 15” loudspeakers are a 2-way design that provide 2400 watts of power via class D amplification. Each loudspeaker is housed in a sleek black cabinet with handles for portability. A built-in mixer with two Mic/line inputs, volume control, and XRL output sits on the back of the speaker with an EQ contour switch and ground lift switch rounding out the controls. The 18” subwoofer is also rated at 2400 watts and features stereo XLR inputs and outputs. The entire system can be controlled wirelessly via the free “Live Drive” app for iOS.


Sound: In case you’re wondering, the Black15 is plenty loud! The 15” loudspeakers provide plenty of bass on their own and the high end is not harsh or brittle in any way. Adding the 18” sub puts out a ton of bass and lets the 15” speakers shine in the midrange. The Live Drive app is incredibly helpful for EQing and fine-tuning the system and even allows you to dial in delay-compensation. Overall, the Black15 is a perfect system for a small to medium sized church and offers power and sound quality for an unrivaled price. Find out more at
