Turbosound TCS152/94-R 15 Two-Way Full-Range Weather-Resistant Loudspeaker with Dendritic Waveguide (90° x 40° Dispersion Pattern, Black)

Terrible Sound

we purchased 4 or these and 4 x QSC. Day one we have been hearing static, hissing sound with. We have checked proper grounding, volume, static controlled everything. The QSC installed in the same hall working without any annoying sound. I have swapped AMP's, MIC's Surge Suppressors everything. But no matter what I do the annoying hissing sound never goes away. I wish I can return these for QSC.
