University Christian Church (UCC), located on the campus of Texas Christian University (TCU) in Fort Worth, recently upgraded its sound reinforcement system in a project headed by Tannoy loudspeakers.

Curt Taipale, owner of Taipale Media Systems (TMS), headquartered in Allen, TX, was tasked with designing the new system. He worked closely with SAV, a Plano-based system integration company that handled the installation.

“The existing sound reinforcement system was more than 20 years old,” explains Taipale. “I worked alongside media and technical coordinator Jack Stewart to nurse it along for a time, but it soon became clear that we needed to make an upgrade.”

The traditional cruciform design of the sanctuary has seating in the main sanctuary along with upper and lower seating in side transept areas. The last pew on the main floor is 120 feet from the main loudspeaker location, with balcony seating that extends back another 20 feet. A beautiful organ supports the choir – both are positioned behind the altar. The most logical place to put the main loudspeaker was on the truss directly over the chancel, upstage of the pulpit location.

“We needed great pattern control from the main loudspeaker,” Taipale adds. “That meant choosing a very large format horn – which would be unsightly – or some type of line array. I chose a Tannoy QFlex 48 column loudspeaker.”

Taipale arranged a demonstration of a Tannoy QFlex 40 in the sanctuary of UCC in order for the church project team to experience his recommendation first hand. Graham Hendry, VP of Tannoy’s Applications Engineering and Support (AET) division, was on site to tune the system and answer questions.

“The uninitiated tend not to believe me when I tell them that one tall, skinny column of loudspeakers can provide even sound coverage to listeners seated in the front as well as 140 feet away,” Taipale says. “The eyebrows really start to raise when I tell them that we can mount such a column vertically against the architectural truss and “steer” the sound energy down onto the listeners.”

The self-powered QFlex 48 is the largest discrete column array in the QFlex series. It consists of four connected modules for a total of sixteen 4-inch LF, sixteen 3-inch LF, and sixteen 1-inch HF drivers, each with its own discrete channel of amplification and integrated DSP (totaling 48 channels).

Once the project team gave the approval, Taipale built the acoustical model using EASE. In order to minimize how far the QFlex 48 protruded below the truss, it was mounted as high as possible, and as a result, the next truss out in front of the QFlex 48 blocked the HF section for listeners seated in the last six pews on the main floor. Taipale resolved that issue with the placement of a single Tannoy VLS 15 loudspeaker on a nearby truss that was aimed to cover those last few rows.

“In fact, we used a total of 14 Tannoy VLS 15s in the project,” Taipale continues. “Most of them cover the lower and upper side transept seating areas with two more to cover the choir behind the pulpit and another covers the balcony at the back of the sanctuary.”

VLS Series is the first Tannoy product to incorporate proprietary FAST (Focused Asymmetrical Shaping Technology), which delivers asymmetrical vertical dispersion, gently shaping the coverage towards the lower quadrant of the vertical axis.

After the first system was deployed the church membership were complete agreement that the system was performing at a high level. “The project team, church leaders and church membership were beyond happy,” concludes Taipale. “They had not heard services so clearly in quite some time.”
