Mids - tie, but I feel both of them has certain hollowness in some vocals (both uses polypropelene material).

Some models of MX5021 has static hiss, changing the cable helps a lot. Altec speakers are notoriously known for static hiss. There is one more speaker I feel is more balanced and worth looking, the CS21 (disadvantage is that it has no remote control and no treble adjustment). But none of these models can match 621 and 641 models.

I'd agree there's a considerable amount of hiss emitted form the tweeter, especially listened from less than 1 meter distance.. I wonder where you get the information that changing cable can help with the hiss?  

Yeah same question here I have with Aquanox what cable is suitable and where can I buy them?

my ADA885 is two years old plus...i doubt there is any1 selling these cables..but do i really need to change mine? or is it just with some of the altec speakers?

u mention burn-in? i tot burn-in is like letting a new speaker blast for a certain period to achieve its expected performance?

oh yea..can any1 recommend sound card for me..budget RM100+
apparently theres only audigy value to choose from..? any opinions?

I give MX5021 the edge. FX4021 - if you try to listen to this speaker, you'll notice that it sounds flat, nothing great (same with FX6021). It is the default setting - flat. However, once you hit the loud button in the control pod (loud increases the treble and bass setting), then you will appreciate this speaker better. MX5021 is the reverse, it is a bright speaker, must decrease the treble. That's the reason most people will immediately jump for MX5021 because it places much emphasis on the high notes. If I breakdown them:

Highs - MX5021 is ahead (decreased treble).
Mids - tie, but I feel both of them has certain hollowness in some vocals (both uses polypropelene material).
Lows - tie, both are not punchy, just low frequency sound but not boomy like the VS4121 model. FX4021 claims that it has isobaric subwoofer to make it stronger, but I can't feel it, something could be wrong with their design.

Some models of MX5021 has static hiss, changing the cable helps a lot. Altec speakers are notoriously known for static hiss. There is one more speaker I feel is more balanced and worth looking, the CS21 (disadvantage is that it has no remote control and no treble adjustment). But none of these models can match 621 and 641 models.

No need to change ADA cables (unless broken). Those were the days that Altec makes quality products. The ADA series is like glory days for Altec. Now they have MX, VS, FX that has so many problems. Yeah, burn-in is for new speakers only, like a heating up period. Sound card.....how about Philips Aurilium, don't know the price now, but it's quite cheap.

Added on February 10, 2007, 11:47 pmmango mind to tell me wat SC u r using?might gona get 1 since that SC come wif remote

haha... true... tested MX5021 before i bought CS21... and here is some review and comparison of both speakers...

http://www.behardware.com/articles/493-12/...er-systems.html

according to this website, overall sound quality CS21 get 8 and MX5021 got 6.5... but highest is FX6021 which are much more expensive...

anyway, shinjun, im using a SB audigy 4... i don't really recommend it but it comes with a remote and its sound much better than a intergrated SC...
