ISIS Series Multipurpose Loudspeakers are no longer in production
QSC Audio will continue to support and service these products.

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. These new loudspeakers offer greater versatility, better value, and increased performance to an already exceptional product line.

These ISIS loudspeakers are full range, two-way models featuring selectable active (bi-amp) or passive crossover operation. Finished in textured black Lynex-coated 13 ply Baltic Birch, they are an ideal mid/high complement to the ISIS 215PCM subwoofer.

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.

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
  • 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)
