Surround 5.1 low frequency speaker test

Описание: With this test you can explore, how your hi-fi device mixes the surround channels to the loudspeakers. Even if you haven't got the rear speakers and/or sub-woofer, the surround and LFE (Bass) channels might be mixed to the existing speakers. The mixing method depends on the type of your hi-fi device and the actual settings of your device.
