German manufacturer HK Audio has launched its new Cohedra line array system at PLASA. The development phase for Cohedra alone has taken more than two years, during which the focus has been on phase linearity, ease of use and above all, natural dynamics, hence the name Cohedra - Coherent Dynamic Response Array. In terms of unit size and weight, Cohedra falls into the category of compact line array systems, so will offer significant handling advantages. The company has chosen not to integrate bass speakers into the flown array, instead going with a new external bass solution (although no specific details on this were available at time of going to press). Since March, prototype systems have been used at several major music festivals and events, including recent testing in concert with Deep Purple and Lynyrd Skynyrd.
