Auralex ProGO-26 Portable, Two-sided ProPanel Gobo

The ProGO-26 is a portable, two-sided ProPanel absorber built into a black melamine-laminated base with casters, so it moves easily between a stage, classroom, or studio without losing the isolation of a mounted panel.

It stands 2 ft wide and 6 ft tall at 4 in thick, and it's effective for controlling early reflections or working as a bass trap when angled across a room's corners while keeping line of sight to performers.
