The use of a plane wave tube (PWT) is standard practice for the testing of audio compression drivers, as the damped tube provides an acoustic impedance load for the driver that is similar to an infinitely long horn of the same throat diameter. When properly terminated, it is anechoic. Uses of plane wave tubes for compression driver testing:
