Precise will and powerful bass. Was only surprised what I got for a block. The rubber feet protect the subwoofer well off the ground so that no beebt the whole apartment. When an action movie explosions and collisions come now very realistic over so that you feel part of the action. In music, the electric guitar sounds now really angry; as does listening to music now even more fun. BUT, if you do not have AV receiver, a stereo or any other device with a SubPreOut, Subout or LFE connection, one need not have to buy the subwoofer. Because the integrated, active Frequentzweiche has only a slope of 12dB / octave. This well audible midtones the subwoofer even again what the listening now not at all to come good. However, anyone who has a device with Subout, this device you can buy with a clear conscience and get a excellent good quality into the house.
