Rock Church, a 3,000-seat worship venue in San Bernardino, California, wanted to upgrade its sound system after discovering that most of the former system had stopped working. After several demos with manufacturers, Rock Church’s audio engineer, Darwin Tillery, and his team chose K-Array due to its digital steering that reportedly saved the congregation money, space and power.

‘With K-array, we were able to go with the smallest loudspeaker hang to preserve our site lines to our side screens,’ Tillery said. ‘Fewer boxes saved us lots of money and we saved on weight too, so less rigging was required. There was no structural engineering either since the new system was a fraction of the weight of our previous system.’

The church was equipped with four K-Array Mugello-KH2 line array loudspeakers and two Thunder-KMT21 subwoofers on each side of the venue. On each side, one KMT21 was installed on the floor while the other was flown. ‘At Rock Church, we have almost 3,000 seats and it's super wide,’ Tillery added. ‘We were at 100dB with 103 peaks at 71 feet with just four boxes per side. These boxes sound louder than they look. Everyone just stares at it saying, “How are you getting it to breathe that way?” With the full band we expected to run out of PA, but we didn’t. Nothing was harsh, we had chest thumping bass and it just works. The way K-array crosses over from the subs is much higher than other manufacturers. It’s not what you’d expect when you’re crossing from 21-inch subs to the eight-inch drivers in the KH2s, but the sound is seamless and more musical.’
