 WF-15 is a high performance broadband systems, compact box, a trapezoidal full-range speaker, which can produce a large box for the sound pressure values. 
 Configure a 15-inch (380mm) low frequency extension of the frequency response, and a 1.75-inch drive (44.4mm) compression driver for the device in a point of 80 ° × 50 ° of the horn. 
 It is particularly for the small theater where the design. It produces an extension of the bandwidth and the use of ICTTM technology for more power requirement, ease of installation.
