Scala 90




  • Constant Curvature Array
  • Medium throw system that can deliver exceptional intelligibility, headroom and power
  • World class PA system, designed for theatres and opera houses, clubs, auditoriums and houses of worship
  • Up to 135° of vertical or horizontal coverage with just 6 elements
  • 139 dB SPL (Peak)
  • Designed for bi-amping
  • Just 21 kg, aiding safety and easy deployment


Outline SCALA 90 is a medium-throw, Constant Curvature Array enclosure weighing just 21 kg yet capable of a peak SPL of 139 dB.

Its usefulness is extended by its ability to be arrayed in either vertical or horizontal orientation, for example with just six cabinets providing a full 135-degree coverage in both deployments. A single element produces a nominal dispersion of 90° x 22.5° (H x V).


Scala 90 is designed for venues such as theaters and opera houses, clubs, auditoriums and houses of worship. The enclosure mounts two 8” partially horn-loaded mid-woofers with neodymium magnets and a 3”-diaphragm compression driver (1.4” exit) loaded on a waveguide with a unique proprietary design, ensuring the lowest possible distortion levels and greater reliability.


Scala 90 implements the Outline V-Power concept to specifically control the coupling between the array modules, and all the radiating surfaces of the cabinet are perfectly symmetrical. The suspension hardware is designed to be unobstructive for installations.


The cabinets are constructed from birch plywood finished with high-tech black polyurea free scratch finish and the grill has an epoxy powder coating.

Scala 90
 is fitted with ten M10 threaded rigging points made of corrosion-resistant anodized aluminium alloy (Ergal) allowing suspension and safety cable attachments.
