Today, the Pennsylvania Turnpike runs through a community of around 3,600, located roughly halfway between Philadelphia and Trenton, that bears the name of its founders, John and Rachel Feaster.

St Stephen’s Lutheran Church A few blocks north of the turnpike in downtown Feasterville, St Stephen’s Lutheran Church offers two traditional services each Sunday, delivered with the support of the Renkus-Heinz loudspeaker system that A/V contractor Steeple Sound installed in 2018. The aural experience would have been quite different just a couple of years ago.

‘This is the third sound system that the church has had,’ recounts Steeple Sound’s Gary Creely, who designed the new Renkus-Heinz-based sound system. ‘The first system used the older column-style speakers, mounted on the sidewalls. A little later, they went to a speaker that was really close to the ceiling, so it was exciting all the surfaces up there. You were getting very little direct sound, except for a small portion of the room, and you were hearing all of the reflections off of that large ceiling area.’

St Stephen’s services feature spoken word, organ, choir, and sometimes piano. It’s not a rock-and-roll church, and the sound system does not need to deliver high sound pressure levels or extended low frequencies. Subwoofers are unnecessary here. The most important consideration is spoken word intelligibility.

‘The room is not tremendously reverberant,’ reports Creely. ‘However, it is somewhat long, and I wanted to avoid a delay set of speakers halfway back because of the challenges with time arrivals that you get into with a delay set. We chose a pair of Renkus-Heinz Iconyx IC8-RN digitally steerable arrays for the main portion of the room because Iconyx loudspeakers cover a wide area, and they also have good reach. We could cover all the way to the back of the sanctuary using a single IC8 cabinet on each side.’

In many church installations, the main loudspeakers are mounted on the front wall. But in Creely’s view, that design is not always ideal. ‘Generally speaking, we try to put the speakers in a plane that is in front of the microphones, rather than behind them,’ he points out. ‘Sometimes, if you’re careful, with the Iconyx you can shoot beams over the microphones and not have an issue with feedback. But at St. Stephen’s, we wanted maximum gain before feedback.’

To achieve this, Steeple Sound mounted the IC8-RNs on the left and right sidewalls, just in front of the stage area, near the front row of pews. The column arrays are painted white to match that part of the wall, so they’re visually unobtrusive. Creely would have preferred mounting them even a bit more forward, but because of the location of the door, that wasn’t practical. ‘It doesn’t cause a problem because the speakers’ dispersion is so wide they’re getting coverage even into that front row,’ he explains. ‘That’s why we placed them where they are.’

Creeley chose a pair of Renkus-Heinz CX41 compact four-inch coaxial loudspeakers to provide a bit of fill for the area behind the IC8 coverage area, where the pastor and people helping with worship sit. Each CX41 can deliver up to 89dB SPL peak, more than enough to easily fill the stage area at St. Stephen’s. Another advantage is that the point-source loudspeakers are so small you barely notice them mounted just below the bottom of the ceiling.

The choir loft at St Stephen’s is at the rear of the sanctuary. Although the Iconyx IC8-RN arrays reach that area, Creely filled in the loft with a couple of CX61 compact two-way Complex Conic loudspeaker systems. The CX61’s 6.5-inch woofer and 1-inch titanium high-frequency driver can deliver up to 120dB SPL peak, far more than is needed to fill the loft, so they are just turned up enough to ensure the choir enjoys clear, rich sound.

A QSC Q-Sys Core processor manages signal routing and processing and provides mixing, while Crown amplifiers drive the Renkus-Heinz loudspeakers. Steeple Sound provided a touch screen in the back of the sanctuary for primary system control and a second touch screen in the front to enable quick adjustments on occasions when nobody is running sound in the back. Shure microphones serve the pulpit, while an Audix MicroBoom system captures the choir. Audio-Technica wireless microphones complete the mic collection.

That completed the sanctuary loudspeaker system…

‘We gave them a small additional CX61 and a speaker jack outside because they occasionally do outdoor functions,’ Creely adds. ‘They can put the CX61 on a speaker stand and run services out there using the wireless microphones.’

The new loudspeaker system is a huge improvement for St Stephen’s Lutheran Church. ‘All of the speakers are much closer to the people’s ears than with the earlier systems,’ Creely emphasises, ‘not to mention that the Iconyx digitally steerable line array is laser-focused on them. It’s a night and day difference.’
