At seven kilos, the Blaupunkt PS 2000 Boombox is not exactly lightweight, but it is still transportable. The Bluetooth speaker has two 25 watt RMS boxes. The sound can be variably refined with the pre-installed equalizers or with the Superbass controller.
A notice: Among other things, the operating instructions warn against exposing the device to direct sunlight. So it’s better to park the boombox in the party cellar, just to be on the safe side.
