Alto Black 15S 15" Active PA Subwoofer - Nearly New

Full Description

Beyond their differences in transducer size, each Black Series sub contains the same 2400 watts of earth-shaking, low-end power and specifically crafted, purpose matched components for maximum efficiency. The Black 15S comes with a 15" transducer, stereo inputs and outputs, adjustable level and polarity controls and precision-engineered cabinets.

Although Black Series Speakers are precise and fine-tuned, they are anything but fragile. Each one comes ready for pretty much anything the road can throw at it, even the rubber feet are reinforced with steel. Perfect for touring rigs, mobile DJs and other on-the-road applications, each one has a heavy-duty 18mm hardwood plywood cabinet covered in rugged, extremely durable scratch-resistant finish. They're also surprisingly lightweight and portable with comfortable, custom-molded handles.

Live Drive is the wireless remote control app available for iPhone, iPod touch, and iPad. Available at the App Store, Live Drive for the Alto Professional Black Series provides remote wireless control over the internal DSP/EQ, Delay-Compensation, Level and Mute status. The Live Drive app allows each Black Series loudspeaker and subwoofer to be quickly re-adjusted at any time, and from any location to assure peak performance in every venue.

Let your audience be amazed by the Alto Black Series Subwoofers. Ideal for installation in amphitheatres, clubs and more, your audience will hear and feel the high-powered, thunderous bass that delivers a breathtaking sonic experience.
