The Z-3s are a standard 2.1 speaker system, and this may be their biggest turn-off to potential buyers who have now been indoctrinated to the features that 5.1 and 6.1 systems offer, thanks to the plethora of such products out there and the resultant marketing about them swarming about. However, 2.1 systems still have their merits; for those that don't want or don't need surround sound, or for those who have limited space, or for those who simply want a no-nonsense speaker set for another computer, a decent 2.1 system can be more than enough. However, there is no denying that you certainly won't get the same experience from watching a movie or playing a game with a 2.1 system as you would with a 5.1 setup, for many people this isn't an option due to space constraints.
