Rubik’s Cube Subwoofer from Elac
The 4.7kg heavy MicroSub 2010 BT from Elac has four amplifiers and it’s completely vibration free. According to Shiny Shiny, it uses Bluetooth to stream music from any enabled device. Alternatively, you can connect it directly using an RC jack.
There is no info on pricing or availability yet. But, as Pocket-lint points out; it will most likely be quite expensive, considering the standard black or white MicroSub model will set you back around $1,800 USD.
