What is it?A passive speaker range designed as a replacement for the DLX Series in touring, rental and fixed installation applications. DetailsThe Delta Series utilises high-output, low-distortion cast frame woofers with 3” voice coils together with 2” titanium compression drivers coupled to 90° x 45° elliptical waveguides said to offer “impressive” output levels and smooth HF dispersion. The range currently comprises eight models: the Delta-12 and Delta-15 2-way full-range models houses 12” and 15” drivers and are capable of handling 800W and 1000W respectively. The Delta-12M and Delta-15M are wedge-shaped enclosures offering similar performance but are designed for stage monitoring applications. The Delta-215 is a ‘Quasi 3-way’ enclosure housing dual 15” woofers and capable of handling 2000W across a 45Hz – 20kHz range. The three remaining models – the 700W Delta-15B, 800W Delta-18B and 1600W Delta-218B – are all subwoofer designs handling frequencies down to 42Hz, 38Hz and 30Hz, respectively. Constructed from plywood with dual-angle pole mounts, Delta range enclosures employ Wharfedale’s new Rhino Rock texturised composite finish said to combine the look of a painted finish with the durability of a carpet covered enclosure. Comprehensive rigging points are provided on Delta 12 and Delta 15 models which are said to be equally suited to groundstacked, pole mounted or flown applications.
