The Phonic Center loudspeakers provide high power handling, low distortion, and consistent polar response in compact, scratch-proof enclosures. The Center speakers come in 2-way and subwoofer models, and feature 10" to 18" low-frequency drivers matched with 1" compression drivers (with exception to subwoofer models). The Phonic Center speakers have a number of sound reinforcement applications: as main front-of-house loudspeakers in small venues, as floor monitors for musicians (Center 12M), for bass enhancement ('?SB' models), or as side-fill loudspeakers in larger systems. Most models can be suspended from ceilings and angled for better coverage, or mounted onto stands, poles and trusses. With the versatility of the range, the set-up possibilities are virtually endless with the Phonic Center series. 18" subwoofer system Frequency response: 35Hz-200Hz Power rating: 500W RMS, 1000W program Rugged construction and internal bracing reduces acoustic losses Top-mounted pole receptacle for easy expansion Constructed from A-grade MDF and finished with anti-scratch paint Dimensions Height: 690mm Length: 560mm Width: 600mm Speakers Nominal Impedence: 8Ohms Output (70V, 100V): Power Handling: 1000 Sensitivity: 99dB Tweeter: NOInch Woofer: 18Inch
