St. John’s sound system, installed in 2000, wasn’t able to provide acceptable intelligibility or coverage and it had a recurring feedback issue. In 2011, Eric Johnson of Audio Video Group offered St. John’s a new system using Community’s ENTASYS column line-source loudspeaker system. As part of his proposal, Johnson performed a live demonstration for the church that showed his design could provide intelligible sound with even coverage while minimizing audio feedback.
