The 3D3A Lab's Listening Room was designed to be similar to a typical home or studio environment. The level of sound reflection can be controlled by repositioning absorptive fiberglass panels (RealTraps RFZ Panels). There is a wide selection of loudspeakers ranging from passive concentric to electrostatic loudspeakers and powered subwoofers. A survey of the directivity of loudspeakers in use at the 3D3A Lab can be found here.
