Measurement Data


  • Designed for wide bandwidth response - These compact and powerful 2-way modular speaker units can be used in multiple configurations as required to deliver greater output power with a more extended frequency response.
  • High-performance driver units - Each Type A Series speaker module contains a 30cm (12") low frequency unit and a high-frequency horn attached to two compression drivers for greater output.
  • Wavefront control - The horn incorporates a proprietary phase wavefront control throat that functions to obtain the best possible performance from the high frequency drivers.
  • Adjustable sound coverage - Type A Series provides two speaker configurations designed for specific coverage characteristics, each having a different taper. The 5-degree taper is for effectively transmitting sound over distance while the 15-degree taper is optimized for excellent short range coverage.
  • Simple maintenance - Maintenance and servicing are made easier on the Type A Series to suit it for permanent installations. All driver replacement is possible from the speaker's rear, a simple and speedy procedure.
