[. . . ] ISIS Series Multipurpose Loudspeakers ISIS Multipurpose The ISIS 102M, 102W, 122M, and 152M are compact, portable, multipurpose loudspeakers that extend QSC's commitment to the corporate industrial and special events market. [. . . ] QSC's ISIS multipurpose loudspeakers are constructed from the finest components. To produce maximum output and work efficiently in any application, all models feature a 1. 4" exit, 3" titanium diaphragm compression driver. The "M" models employ a spherical (60°) HF waveguide for even dispersion regardless of orientation and a high-power neodymium woofer for reduced weight, while the "W" model offers an exceptionally wide coverage pattern (150° x 50°) via a rotatable waveguide. All ISIS multipurpose loudspeakers feature a full assortment of versatile hardware to make the task of rigging and installation a straightforward process. Integrated fly track hardware on top and bottom plus an independent rear center point allows for easy, safe rigging. Each model has a dedicated yoke mount accessory available, and there's also a built-in pole cup for stand mounting. The symmetrical multi-angle cabinet design facilitates both FOH and stage monitor applications. Key Features Neodymium woofers (122M and 152M) and compression drivers provide reduced speaker enclosure weight Integral L-track flying hardware (top and bottom) facilitates safe and easy rigging Cored Composite construction (ComposiliteTM) and foam backed stainless steel grills provide excellent weather resistance for outdoor applications Suitable for both FOH and stage monitor applications Multipurpose cabinet design comes in 3 sizes; accommodating 10", 12", and 15" LF drivers All models are designed to complement the ISIS 215PCM subwoofer, which provides DSP processing and amplification for any accompanying 2-way enclosures, thus creating a self-contained, self-powered, 3-way system Switchable passive/active crossover modes--flat response for quick setup and use (passive crossover mode); Extremely flat and accurate active (DSP) voicing for bi-amped applications (active crossover mode) ISIS Multipurpose Specifications Frequency Range (4) Frequency Response (4) Maximum Output Calculated Peak Output Calculated Continuous Output Continuous Noise Exposure Level Impedance, Nominal Power Rating Recommended Max Amp Power RMS Power Handling (IEC) 8 hours Sensitivity 152M Passive Mode 45 Hz - 21 kHz (-10 dB) 55 Hz - 20 kHz (-6 dB) 126 dB SPL 120 dB SPL 120 dBA 8 700 W 350 W 96 dB, 1 W, 1 m, free field 152M / 122M Specifications and Frequency Response 152M Bi-amp Mode* 45 Hz - 21 kHz (-10 dB) 50 Hz - 20 kHz (-6 dB) LF: 127, HF: 133 dB SPL LF: 121, HF: 127 dB SPL 120 dBA LF: 8 , HF: 8 LF: 700 W LF: 350 W HF: 160 W HF: 80 W 122M Passive Mode 50 Hz - 20 kHz (-10 dB) 60 Hz - 19 kHz (-6 dB) 126 dB SPL 120 dB SPL 119 dBA 8 700 W 350 W 95 dB, 1 W, 1 m, free field 122M Bi-amp Mode* 45 Hz - 20 kHz (-10 dB) 55 Hz - 19 kHz (-6 dB) LF: 127, HF: 133 dB SPL LF: 121, HF: 127 dB SPL 120 dBA LF: 8 , HF: 8 LF: 700 W LF: 350 W HF: 160 W HF: 80 W LF: 96. 5 dB, 1 W, 1 m, 100 Hz - 1 kHz HF: 108 dB, 1 W, 1 m, 1 kHz - 16 kHz QSC DSP product with appropriate configuration file LF: 96 dB, 1 W, 1 m, 100 Hz - 1 kHz HF: 108 dB, 1 W, 1 m, 1 kHz - 16 kHz QSC DSP product with appropriate configuration file Recommended Processing Optional 45 Hz high-pass >12 dB/Octave Optional 50 Hz high-pass >12 dB/Octave Specifications Controls Transducers 152M Both Bi-amp and Passive Mode Bi-amp/Passive Switch LF: 15" high power woofer, 3" (76mm) voice coil, weather treated paper cone, lightweight neodymium magnet structure HF: 1. 4" (38mm) exit, 3" titanium diaphragm compression driver on low distortion, constant directivity waveguide 60°conical (2. 5 kHz) Ported, tuned to 53 Hz Two Neutrik® NL4-series airtight panel-mount SpeakonsTM wired in parallel 122M Both Bi-amp and Passive Mode Bi-amp/Passive Switch LF: 12" high power woofer, 3" (76mm) voice coil, weather treated paper cone, lightweight neodymium magnet structure HF: 1. 4" (38mm) exit, 3" titanium diaphragm compression driver on low distortion, constant directivity waveguide 60°conical (2. 5 kHz) Ported, tuned to 60 Hz Two Neutrik® NL4-series airtight panel-mount SpeakonsTM wired in parallel Nominal Coverage Bass Loading Connector Enclosure Material Finish Grille Rigging System Dimensions Weight Multi-angle wedge constructed of weather-resistant cored ComposiliteTM, or Lynex coated 13 ply Baltic Birch Textured black Heavy duty stainless steel, painted black Front and rear fly track on top and bottom plus independent rear center pullback/safety point 31" H x 18" W x 13. 5" D 787. 4 x 457. 2 x 342. 9 mm Composite Version: 49 lb.
