The first number, the integer, denotes how many satellite speakers there are in the system. The number after the decimal denotes how many subwooferes there are in the system.
Negitive. 4.1 is how many channels of audio it has. 4 channels plus another for the sub. 4 speakers, in this case, is 2 channels with a tweeter and midrange each plus the sub = 2.1
