Just a test comparing the Edifier Signature (s530,s550,s730,s750) with the Logitech z-5500.

Not much to say,not much to show,mostly because in the video you won't hear any difference of the how both speakers sounds like.
There is a little difference,the Edifier speakers are have more alive frequency response,but you can hear it only if you have good speakers (not Logitech),or good headphones.

In this test i aimed the mid-range frequency response,and the bass.

I noticed that the Logitech speakers cannot produce any midrange frequency with the ease the Edifier speakers do.

The Logitech amplifier is well made,but not calibrated for this kind of speakers,because for example it sends signal below 100hz to the satellites,but it's bad because the plastic cabinet does not tune to these frequencies,and the result is bad.

The Edifier amplifier can send signal down to about 130-150hz to the speakers (150hz-22khz official specs),but the wooden cabinet plus the two way crossover,makes it sound as good as it designed to be.
However i found the Edifier speakers sounding a little bit confusing when the mid and low range frequencies are adjusted from the control pod,and the speakers are playing low frequencies.
Also when the volume is nearly max,the THD level is the same as the Logitech speakers,but the Midbass driver (130-150hz to 10-12khz) is producing a little bit of intermodulation distortion,and the tweeter sounds sharp.

The Logitech speakers on nearly max volume also producing intermodulation distortion and high audible levels of THD,and the lack of tweeter plus the inefficient cabinet,makes a result of sharp sound in all the frequency ranges (at least those who can play).

The enclosure of the subwoofer of the Logitech and Tangband driver are not the best combination for a subwoofer.

The result of this subwoofer is loose uncontrollable bass (it's too boomy),not too deep,and the subwoofer also due to enclosure design can play midrange frequencies,at least it gives you the feeling of a "tinnitus" of midrange frequencies.
I noticed the same thing with the Edifier subwoofer when i removed the one of the two passive radiators.

The Edifier subwoofer is producing more tight bass,deeper and cleaner,and it also fills my room with bass better,because of the Passive Radiator Enclosure.

With the Edifier s550 (5.1) costing this moment 250-300 euros (338-406 USD),
and the Logitech z-5500 (5.1) going from 300 euros to 500 euros (406-677 USD),
i found the Edifier speakers cheaper and more comfortable to ear for a better listening experience,
without the need to jealous something from the z-5500,because they are providing you louder sound than the Logitech,better frequency response,and are suitable for all the Multimedia applications,plus casual music listening.

Edifier - 8* Best Buy at this Price
Logitech - 4* A little bit Overrated and Overpriced
