custom made steel structure for supporting the new equipment
Community R6-52 and R2-474 loudspeakers cover every seat in Franklin Field from one compact cluster. The R-6 speakers have eighteen drivers each: six 12”, six 2” horns and six 1” horns.
Clear Sound designed an entirely new system for the stadium.
A Terex Stinger crane hoists the R-6 into place, mounted inside a custom fabricated steel cradle.

Every year, tens of thousands of fans crowd into the historic Franklin Field stadium at the University of Pennsylvania to enjoy the Penn Relays:  a fast-paced track and field event that has been a Penn institution since 1894.

Three weeks before the 115th annual Penn Relays were to begin, Penn’s athletic director realized that Franklin Field’s 27-year-old sound system was no longer functioning.  His first call was to Clear Sound.  Within hours, a team of sound specialists was at Franklin Field, assessing the situation and making a plan to meet the impending deadline.  Working with engineers at Community Professional Loudspeakers, Clear Sound designed an entirely new system for the stadium.  Since the antique roof of Weightman Hall couldn’t support the weight of modern speaker clusters, a mechanical engineering firm created a custom made steel structure for supporting the new equipment.  Clear Sound oversaw the design, construction and installation of the platform, as well as the installation of the new loudspeakers, which had to be lifted into place with a crane.  Thanks to the team’s focus and expertise, the entire installation was finished within three weeks.  Fans will now be able to enjoy unprecedented sound quality during the Penn Relays for years to come.
