- Electro-Voice EVID Compact Sound systems hidden amid ceiling elements create calm, welcoming ambience throughout art gallery
- Southwest Building Systems designed the system to meet gallery requirements for high fidelity and intelligibility with minimal visual impact
- Bosch PLENA matrix mixer provides wireless control of all audio in gallery, controlling zoned loudspeakers via iOS app
For their Art of the World Gallery in Houston’s River Oaks area, co-owners Liliana Molina and Mauricio Vallejo wanted to augment their guests’ appreciation of the outstanding contemporary artists they display. Southwest Building Systems of nearby Silsbee was engaged to realize this vision, and an audio visual system was installed to support artist presentations and provide background music. There is also a sound system in the VIP room, where patrons can privately view art they are considering for purchase.
“The idea was to create a warm, comfortable ambience throughout the gallery, while keeping the visual focus on the art itself,” says Brent Thornhill of Southwest Building Systems. “We knew that a combination of Bosch signal processing and the new EVID Compact Sound loudspeakers by Electro-Voice could produce the audio impact they wanted while being, essentially, invisible.”
To meet the gallery’s requirement of consistent, high-fidelity sound throughout their two-story space, Southwest Building Systems used a zoned distribution system, the Bosch PLENA matrix mixer (model PLM-8M8). Easily implemented, the mixer allows independent control of source material and volume, either directly through wall-mounted Bosch control panels and volume controls, or wirelessly through the Bosch PLENA app for iOS devices.
Because the gallery hosts presentations by the artists it exhibits, a separate sound system was needed for the front foyer and reception area. For this open space, Thornhill installed an Electro-Voice R300 wireless microphone system with both handheld and bodypack transmitters. A single Electro-Voice EVU-1082 loudspeaker, mounted above the reception desk, provides full-range, highly intelligible audio at modest volume levels from both spoken and musical sources.
The primary background audio for the main gallery spaces is provided by the EVID S44W Compact Sound system from Electro-Voice, which consists of four small satellite speakers and a single subwoofer, finished in white. Four such systems are spread throughout the gallery, with the tiny yet robust satellite speakers mounted to the ceiling beams and the compact subwoofers installed atop floating ceiling structures, making them completely invisible to the patrons. In addition, 16 Bosch LB2 speakers at ceiling level along the periphery ensure that every corner of the gallery is covered uniformly.
The final touch is the Art of the World Gallery VIP room, where clients can arrange private viewings of a piece they are considering for purchase. This private room is set up as a separate audio zone, with music provided by a single Electro-Voice EVID FM 4.2, a two-way, flush-mounted speaker set into the wall along with a Bosch rotary volume control. Co-owner Mauricio Vallejo liked the sound quality so much, he had one installed in his own office as well.
Vallejo is extremely pleased with both the sound quality and control that the system delivers for Art of the World Gallery. “Southwest Building Systems gave us everything we asked for, with clear, beautiful sound everywhere,” he says. “To have total control of the sound system, anywhere in the building, from my iPad or iPhone, is something we all love. It makes everything easy and professional, enhancing the viewing experience without interfering with it. We are very pleased.”

- Installation was part of a three-year renovation to transform the facility into a destination for world-class sports and entertainment events
- Over 3,000 loudspeakers provides seamless coverage to all seating areas, concourses, offices, and public areas
- Comprehensive system was designed and installed by Diversified Systems in collaboration with the Bosch/Electro-Voice team
Hard Rock Stadium is owned by, and home to, the NFL Miami Dolphins. It also hosts University of Miami football and major entertainment events throughout the year. As part of a three-year, facility-wide renovation, the re-named facility now boasts a massively upgraded sound system by Electro-Voice.
With the stadium’s addition of a roof and massive video displays, crowd noise levels are substantially higher than the original open-air design, making even coverage critical, both in terms of SPL and frequency response. In addition to the primary task of improving the fan experience through better audio, the sound system is also used for mass notification of life safety information. The Dolphins selected Diversified Systems to design and integrate the system, charging them with the task of overcoming increased levels due to roof reflections while delivering both vocal intelligibility and musical fidelity.
Drawing from all parts of the diverse yet sonically matched Electro-Voice loudspeaker portfolio, the installation delivers concert-quality sound via 186 XLCi-127DVX line array elements, weatherized and integrated into custom-engineered frames to withstand extreme storm and wind conditions. These are augmented by EVF-1122S front-loaded loudspeakers and EVH-1152D long-throw loudspeakers to cover hard-to-reach zones like corner seating areas. In addition, 48 dual 18-inch subwoofers, custom designed for the project, add an exciting bass element that was absent in the stadium’s previous system.
An ongoing installation challenge was the management of the installation across the renovation’s phased construction timeline, requiring ongoing support of the legacy sound system while the new Electro-Voice system was being installed, tuned, tested, and deployed. To ensure even coverage throughout all seating areas, EASE modeling and intelligibility plots were critical tools in selecting the appropriate loudspeakers and their placement. Two Electro-Voice NetMax N8000 digital matrix controllers allowed the integration team to apply FIR filtering to optimize loudspeakers as needed and appropriate.
In addition to the primary task of improving the fan experience through better audio, the sound system is also used for mass notification of life safety information. Electro-Voice ceiling and surface-mount loudspeakers ensure smooth, continuous coverage in luxury suites, concourses, restrooms, offices, and all public areas throughout the stadium. This task required approximately 1800 ZX1i indoor/outdoor loudspeakers and over 1000 EVID ceiling-mounted designs selected from EV’s wide range of options.
The Dolphins team are pleased to report that the system has exceeded their performance expectations while meeting budget and timing requirements. The system is at its best when the stadium is full, enhancing the fan experience with clear, effortless coverage, and rising to the occasion to amplify crowd energy in big moments.
Whether deployed for sporting events or major concert events, Hard Rock Stadium offers a winning combination of full-range fidelity, comprehensive coverage, and high intelligibility that plays a key role in transforming the venue into global entertainment destination for large-scale events.

For the recent North American International Auto Show in Detroit, Aerial Enterprises was the PA system provider for the main Atrium Stage in the Cobo Center. To provide both the musicality required for artists like the Beach Boys and easy intelligibility for keynote addresses, black tie events, and awards presentations, Aerial selected the X-Line Advance line-array loudspeaker system from Electro-Voice, with EV power and processing.
The main system consisted of two nine-box line arrays of X2-212/90 mains, supported by twin six-box clusters of X2-128 subwoofers, deployed in a cardioid arrangement for bass control within the cavernous space. The system was powered by TG7 amplifiers and networked via the NetMax N8000 digital matrix.
To augment the mains, Xi-1122 full-range loudspeakers were used, with four for front fill, six for deck fill, and six more as a delay system for the first balcony of the large three-story hall. These were powered by CP3000S amplifiers with Dx46 processors.
“The key to choosing X-Line Advance for the Detroit Auto Show was its ability to sound good for a wide array of event types, from voice only to major entertainers,” notes Jim Lillie, President and Operating Partner for Aerial Enterprises. “It was a great example of how versatile the X2 system is. Everybody was extremely pleased.”

The recently opened Karbala Olympic Stadium in Iraq is a 30,000-seat venue designed to host major sports, music, religious and youth events. Audio for the project was provided by Baghdad-based APCO Electronics, which provided acoustics design and participated in the actual installation as well. The company chose a sound system from Electro-Voice, creating a multi-zone digital audio system based around the IRIS-Net system control and supervising software and Electro-Voice EVH-1152 horn-loaded loudspeakers. The selected sound system stands for reliability, superior sound quality and scalability to future requirements. In addition, Electro-Voice amplifiers, microphones and wireless systems were also utilized.
The primary system requirement was that the sound system would meet FIFA football standards, which require 92 percent direct coverage and high intelligibility, with a Speech Transmission Index (STI) of 0.50 or higher. The installed system exceeds those standards, delivering 95 percent coverage with an outstanding STI (Speech Transmission Index) rating of 0.80, indicating excellent speech clarity. Next to public address announcements, the system should also be used for voice alarm and evacuation purposes.
Using EASE simulation software, the APCO team developed a design based on the Electro-Voice EVH-1152 loudspeaker system, a two-way 15-inch horn-loaded design available in six dispersion patterns. For the specific grandstand angles at Karbala Olympic Stadium, APCO used 24-each of 60×40-degree and 90×90-degree coverage patterns. Paired together, this combination provides direct, full-range coverage to all seating locations, including the difficult corner areas. In addition, two EVH-1152 loudspeaker systems with 90×90-degree dispersion are deployed individually at either end of the field to deliver audio onto the playing surface as needed.
The entire sound system is networked together using Electro-Voice N8000 Dante- enabled DSP matrix controllers and powered by Electro-Voice CPS series amplifiers with RCM-810 remote control modules. The N8000 from Electro-Voice provides complete system routing and control via graphical user interface in IRIS-Net software. The main loudspeaker system is divided into four zones, each with its own N8000 from Electro-Voice and either three or four amplifiers, with the east side zones requiring and extra amplifier to feed the field speakers. All amplifiers are connected to their associated N8000 via a gigabit Ethernet switch to handle signal routing, with redundant connectivity to ensure a reliable digital network. A fifth N8000 is stationed in the stadium’s main control room, and acts as the master unit for the entire system, routing the audio to each of the four individual zones. APCO programmed the signal processing core to handle all required audio sources, including microphones, PC-based streaming audio, emergency notifications and scoreboard audio.
Karbala Olympic Stadium represents the largest Dante system that APCO Electronics has designed and installed. Thus, the feeling of accomplishment was strong when the APCO team finally heard the Iraq national anthem being played through the Electro-Voice system at the opening ceremonies. That feeling was reinforced shortly after the event when APCO received calls from the Minister of Youth and Sport, and from local broadcaster Ishtar Media, thanking them for the outstanding audio quality.
