QSC K8

I'm currently installing all of the sound equipment for the studio. I will be using this studio for private lessons, group lessons, rehearsing for kids and adult bands, and recording. I can wait to use this equipment soon! Here are the specs on the QSC K8- 

Features

• 8-inch Woofer; 1.75-inch diaphragm compression driver
• 105° conical DMT coverage
• Maximum SPL 127 dB peak

• Attractive and professional appearance
• Rugged ABS enclosures

• 16-gauge powder coated steel grille

• 1000-watt continuous Class D power modules in all models
• Comfortable ergonomic handles
• 35 mm pole sockets with Tilt-Direct™
• M10 rigging points
• Eyebolt and yoke mount accessories available

• Onboard mixer with two combo XLR and ¼-inch inputs, and stereo RCA inputs, (three audio input sources); two direct channel outputs and single summed balanced output
• Extensive DSP enhances system performance:
• DMT™ (Directivity Matched Transition) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural "dead" or "hot" frequency zones.
• Intrinsic Correction™, first featured in our high-end line-array products maps 65–75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat band pass target. The result is a speaker that behaves equally well across the entire sound field.
• DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies.
• GuardRail™ protection protects both the amplifier module and your performance from unnatural and destructive clipping.
