Indoor Outdoor Line Array Loudspeaker (W-28A / W-115A)

W-115B is dedicated high performance sub-bass system designed to augment the low frequency output of the W-28B. W-115B is a sub-bass enclosure which must be flown with W-28B. So its physical dimensions are identical to the W-28B 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-28B 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-28B will integrate seamlessly with the W-115B line array sub-bass system in a standard configuration. W-28B is very versatile and scalable for a wide range of applications in touring performance, corporate and fixed installation fields.
