    Based on Quattuor, Unus is a stereo multimedia speaker system capable of delivering up to 4.7W per channel. Unlike Quattuor that has four controls, this circuit has one control for volume. This video shows the prototype PCB (printed circuit board) being tested, reproducing the music "Bass, I Love You" by Bassotronics. The difference between this and the final circuit (that will never be materialized), is that the final circuit uses two additional bypass capacitors in order to improve supply filtering. The circuit uses two TDA2003 power amplifiers. The board is connected to a pair of Visaton FR 10 drivers. You can notice the output power by the appreciable excursion on both drivers, and you can actually see the dimples on the surround of each driver.
