JBL Control 25-1 5" 2-Way Indoor/Outdoor Speaker Pair 70V / 100V / 8 Ohm - BlackJBL's Contractor Series surface-mount speakers are loaded with complication-reducing innovations. Rugged molded high-impact polystyrene (HIPS) enclosures balance mass, strength, and resonance, perfectly complementing their respective transducers. The symmetrical 100° x 100° dispersion geometry delivers precise directability and control. Compact design dimensions and textured, ready-to-paint exterior surfaces make the Control Contractor Series unobtrusive in any decor. JBL's Invisiball™ mounting system (patent pending), innovative bracketing solutions, and factory-installed autoformers take the headaches out of installation.
Extensive use of high-tech materials adds years to speaker life expectancy while increasing weather resistance. The Control 25-1 exceeds MilSpec 810 for humidity, salt-spray, temperature & UV, and passes MilStd-202F for salt spray and ASTM G85 for acid-air plus salt spray. For extreme environments, MTC-23WMG-1 WeatherMax™ grilles and MTC-PC2 protective panel covers (both sold separately) may be added to increase the IEC rating from IP-44 to IP-55.

Constant Voltage (70-Volt) Audio Systems
Audio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire. The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages. Learn how to design your own 70-volt or 25-volt loudspeaker system.
