To offer some sort of final word here, it's important to consider that these speakers have been designed primarily as a budget gaming system that offers good value and performance for console gamers or PC gamers alike.
They allowing the user to hear and feel all the action of bullets whizzing by and explosions taking place in a real 5.1 environment, which for a $70 street price is outstanding value. I don't think that even buys a single Xbox 360 game, just to put things into perspective.
Movies and music are not great, so don't buy this system to relive the emotion of a great concert or a well recorded piece of music, because you will be disappointed by frequency response and tonal accuracy. To a lesser extent, film is the same, although I see no issues with enjoying any TV program or sitcom that is not recorded in high bandwidth like films are. Even casual radio listening would be fine here, as that's another heavily compressed medium.
Finally, I don't think AL has done a bad job at all in designing this system. As a PC or console gaming system, it does exactly what it says and for a great price!
