DESCRIPTION and APPLICATION
W-28A is a line array system which is made of two 8'' neodymium woofers, a 1.75'' titanium neodymium compression driver and high-performance low-distortion compression driver with innovative horn design of waves phase philosophy. It is a zero interfere line array with multi- speaker combined to produce accurate directivity and maximum dynamic impact. Wherever low frequency extension is required, a W-28A will integrate seamlessly with the W-115A line array sub-bass system in a standard configuration. Each enclosure is equipped with rigging system, allowing flown array to be constructed rapidly and safely. W-28A is very versatile and scalable for a wide range of applications in touring performance,corporate and fixed installation fields.
