The football Academy in Luanda turned to Sistec for a brand new weatherproof audio system during the summer of 2012. For this task they needed an affordable system that would allow them to hang it in outdoor environments but offers a very large spread angle. It did not take them long to decide that the WX802/OB from AUDAC was the speaker they would choose for this project. With its IP55 rating this speaker can be exposed to all weather conditions, while still delivering a true to nature full range sound for all its spectators. To amplify all this power they chose 3 AUDAC Q4 amplifiers together with Q2TR transformers to create a high power 100V system. In total they installed 50 WX802/OB speakers, delivering them more than just background music.
