Built-In Cyc for False-Wall Studios
The System 4BI is a built-in cyclorama wall system designed for studios that need a 42-inch cove radius, expanded corner performance, and space behind the cyc wall for infrastructure.
Unlike System Super 3EZ, which mounts directly to existing drywall, System 4BI uses a 2-inch, 90-degree flange at the top of the floor coves and along the sides of the corner modules. This flanged return requires a shallow false wall for proper integration.
That construction approach makes System 4BI the better choice when your studio needs wiring, conduit, additional insulation, or other building services behind the cove walls.
The expanded corner design combines a 3-foot 6-inch vertical radius with a 5-foot horizontal radius, creating smoother wall-to-wall transitions than a standard 90-degree corner while reducing problematic sound reflections.
