A NEW (ACOUSTICAL) BEGINNING FOR THE LYRIC OPERA OF CHICAGO
Ravenswood Studio recently completed the installation of a new orchestra shell for the Lyric Opera of Chicago. This massive structure designed by world famous Jeanne Gang and Studio/Gang Architects working in conjunction with Threshold Acoustics. Ravenswood Studio was brought in to complete the engineering and fabrication of this complicated structure.

Constructed from custom veneered and finished MDF panels, precision computer cut plywood ribs were attached to steel sub-structures and then clad with the computer cut MDF veneer panels. The entire shell is made up of 34 giant pieces with a 35’ tall back wall, 35’ tall side walls on rolling jacks with concealed doorways, and twenty-one floating roof pieces that complete the ceiling of the structure. The 8,000lb back wall was suspended from chain motors and truss which allow it to fly out for storage. To ensure accuracy in engineering, fabrication and installation Ravenswood Studio mocked up three full scale sections of the shell during the engineering and prototyping phase. This was necessary due to the complex nature of the structures’ compound curves that were designed to curve in multiple directions and to also offer Threshold Acoustics the ability to verify sound reflection properties ensuring proper performance when installed at Lyric Opera.
