EX28

2.5-way Full-range Active Speaker

The EX28 is a 2.5-way full-range active loudspeaker system that builds on the success of the EX26 whilst adding further low frequency extension. Its compact profile makes it ideal for a multitude of FOH and infill applications in Theatres, Leisure venues, Houses of Worship and Concert Halls, where the ultimate quality from a discreet loudspeaker solution is required. Two individually designed 8" neodymium mid - bass woofers offer Transcoil for improved vocal performance and extended bass for the low frequency section, along with a neodymium compression driver mounted on a 100° by 80° horn.

Features

  • Professional Baltic birch construction with wear-resistant polymer coating

  • 126dB sustained output, 132dB peak with very high dynamic range and low noise floor

  • 500W of total power with complete on-board speaker management system

  • 450W high efficiency, current enhancing, switching low-frequency amplifier

  • Very high-quality 50W, low IM distortion, Class AB, high-frequency amplifier with transformer-balanced output

  • Compact low-profile cabinet design allows for use as a front fill or in under-balcony applications with a high pass filter to adjust equalization and phase response

  • Wide dispersion 100° H x 80° V horn

  • SLA Technology 1.75" (44 mm) Titanium diaphragm compression driver with complex geometry phase plug for higher output, exceptionally low distortion, extended frequency response, and neodymium magnet structure

  • Two 8“ woofers feature neodymium magnetic motor structures that dramatically increase force and lower distortion with an additional AIC Trans coil operating on one of the woofers for improved dynamics and definition.

  • Revolutionary new Krampera filtering creates a 2.5-way system for exceptional vocal clarity.

  • Proprietary top and side handle design for simplified handling and carrying; each integrates one M10 suspension point.

  • Additional side and bottom M10 points for flexible brackets, rigging, and installation

  • “Top-hat” pole mount fitted at the base of the cabinet

  • LED indicators for signal presence and Power ON status
