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° rotatable horn.
