hye guys , idk if anyone ask this question or not. Just back from lowyat to audit my potential speakers which are

z623
z506
armagedon a7
c3
z906

i need speakers mainly for movies and gaming , and music a lil bit. Base on what ive heard on 2.1 speaker , z623<armagedon a7<c3 , I love bass but on the z623 i cant control both bass and treble , on the armagedon i can control both , on c3 i dint find it as i was playing with the volume. So is it worth the penny on z623?

Last but not least , z906, i dint set on max volume as it too loud for me but it seems nice, but overexpensive , do u guys know whether c6xd (5.1) is good or corsair sp2500(2.1)? i am gonna check again tomorrow and buy . Thanks in advanced!
