W-115A is dedicated high performance sub-bass system designed to augment the low frequency output of the W-28A.W-115A is a sub-bass enclosure which must be flown with W-28A. So its physical dimensions are identical to the W-28A and it is equipped with the same proprietary rigging system. It features with a 15" neodymium woofer with magnet structure and suspensions engineered for maximum linear excursion.

DESCRIPTION and APPLICATION
W-28A is a line array system which is made of two 8" neodymium woofers, a 2.5" 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.
