ST. LOUIS, Missouri – March 2018 — The Scottrade Center is home to the St. Louis Blues of the National Hockey League but so much more. Besides ice hockey, the 18,724-seat arena, first opened in 1994, annually hosts a range of nearly 200 events including wrestling matches, boxing bouts, basketball tournaments (including the NCAA Women’s Final Four Basketball Championships), concerts, ice shows, family shows, graduations and more, drawing nearly two million guests.
But like other venues of its vintage, the Scottrade Center’s original sound system was not able to keep up with the demands imposed by a wider range of applications that require comprehensive audience coverage, full-spectrum music reproduction, and excellent speech intelligibility. It now has that capability, thanks to the implementation, last autumn, of an AVB-networked L-Acoustics Kara sound system designed by Dallas-based consultancy Idibri and installed by the local L-Acoustics Certified Provider, Logic Systems Sound and Lighting.
The new Kara system, powered by 33 AVB-equipped LA4X and one LA12X amplified controllers, consists of 90 Kara loudspeakers and 36 SB18i subwoofers, divided into six equal arrays of 15 Kara and six SB18i. In addition, six ARCS II, configured in two clusters of three, are positioned facing straight down for ice coverage and special events.
What’s especially remarkable, however, is that this Kara system design provides such comprehensive coverage of the bowl’s seating areas that an option to add under-balcony speakers was abandoned the first day the system was turned on. That wasn’t the first surprise that this project revealed.
“Although L-Acoustics’ K2 was initially specified and provided 6dB more SPL, Kara was eventually chosen because it was able to meet actual SPL requirements for the arena and a tighter budget, allowing funds to cover more aspects of the overall renovation, including updating the AV systems in the locker rooms,” explains Ben Cating, senior consultant and project manager for Idibri, which also designed a new center-cluster video scoreboard system for the arena. Amazingly enough, the smaller Kara boxes were still able to provide the high degree of coverage, volume and intelligibility that the arena project demanded, allowing the budget to be stretched without any compromises.
The Scottrade Center project did have its challenges, but the AV integrator’s expertise combined with the Kara system helped tremendously with those as well. “The primary challenge was to place six arrays in very precise locations in a building with asymmetrical steel and a labyrinth of 10-foot-diameter steel air ducts that always seem to be in exactly the wrong place,” recalls Logic Systems Sound and Lighting President Chip Self.
Kara’s impressive weight-to-power ratio solved that issue. “It was lighter, more powerful, and required substantially less power than the other systems,” Self explains. “Since this project included a huge new scoreboard, which weighs much more than the original, the weight savings was very valuable to the building engineers, as it did not necessitate the addition of any new steel.”
In addition to the new sound system, the renovation also included a rebuild of the arena’s ice floor. The installation also faced a tight timeline, between sports seasons and other scheduled events. “Since the timeline was so very tight, we had limited access to the space,” says Self. “Given lead times on equipment and other elements of the construction schedule, we were not able to start our work in earnest until there were less than 60 days to complete the entire project. To compensate for that, we did a great deal of pre-configuration and pre-assembly off-site. I believe that made a huge difference in getting the project complete on time, and on budget.”
In fact, recalls Cating, all of the Kara loudspeakers were able to be hoisted into place within a single day, allowing the crews to focus on wiring and tuning the system.
The result has been nothing short of a sonic renaissance in the venue. “The final performance exceeds the predictions,” Self observes. “If anything, I’ve found that L-Acoustics are conservative with predictions, which can’t be said of all loudspeaker manufacturers. The intelligibility and directivity are spot-on, and there is headroom for days. Upon completion, the only change we’ve been asked to make is the installation of a 10Eazy SPL monitoring system to make sure it doesn’t get too loud.”
“Last year’s renovations required a high level of expertise, precision and commitment, and I can’t imagine working with anyone better then Ben from Idibri, Chip from Logic Systems and the L-Acoustics team,” adds Scottrade Center Group Vice President and Arena General Manager Alex Rodrigo. “This project was our ‘Mount Everest’ and the team not only reached the summit, but did it in such a professional and knowledgeable way that it was an enormous amount of fun. Our fans and guests are now more engaged than ever and truly blown away by the difference that the new sound system has made. This project has dramatically improved Scottrade Center’s sports and entertainment fan experience for years to come.”
