Akshardham’s Famed Fountains Get Renkus-Heinz Sound

New Delhi, India | September, 2015 - "We have worked with Renkus-Heinz on similar projects in the past, with excellent results, and we were confident that their technology was ideally suited for this type of a challenge.

Renkus-Heinz IC² Steers Grove City Church in Right Direction

Grove City, OH | December, 2014 - "They demonstrated the beam steering by putting us up in the balcony with the IC² cabinet on stage. We could hear it just fine. Then he opens his laptop and says, ‘Watch this,' and steers the speaker digitally so it's hitting us directly upstairs. All of a sudden, boom, there it was, with unbelievable clarity. I looked at my front of house engineer and we both said, ‘That's the one.' It was the coolest thing." - Matt Groves, Grove City Church
