Our Projects
Village of Tinley Park
Harmony Square
Harmony Square is a 1.6-acre multi-use plaza located in downtown Tinley Park, Illinois.
It officially opened on July 18, 2025 as a year-round "living room" for the community, featuring a built-in 30x50' stage complete with d&b audio loudspeakers. Sixteen QSC Audio direct weather landscape speakers are mounted on light poles to provide 360 degree coverage throughout the performance lawn.


Second Presbyterian Church
Bloomington, Illinois
Founded on June 3, 1855, Second Pres is a historic congregation located in downtown Bloomington.
OSA Provided a new d&b audio PA system for the front and side fills, the mains and under balcony delays. We provided ASL technology for the congregation as well as QSC Audio, Shure Handheld and Wireless Microphones. The congregation was thrilled with the new audio and ability to clearly hear the services both in person and during livestream


Outdoor Oasis, Northern Illinois Suburbs
Homeowners in northern Chicago suburbs renovated their property with an inspiring landscape for entertaining during the warmer months. Upon completion of the gardens, they wanted to upgrade the sound system, which originally consisted of a handful of faux rock speakers around the pool, to extend across the entire property.
