DISC Alto Black 15 15'' 2-Way Active PA Speaker

Full Description

Each Black Series loudspeaker features the same core elements, a 1.75" high-frequency driver, 2400 watts of Class D power and carefully selected, complementary components. Designed and fine-tuned in the USA, the Black 15 has a 15" low-frequency transducer and comes optimised with a 90 x 60 degree coverage field and an extensively tested high-frequency waveguide, crafted to deliver maximum sonic impact, creating an energised atmosphere of sound.

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.
