Conclusion

In a nutshell between the 11 tested speaker sets, mainly the two new Altec’s sets seduced us. The FX6121 is put on the side because of its high price justified by an exceptional sound quality. But in order to play or listen to music most of the people don’t need or want to spend that much money. And on the top of that you need to possess a top-of-the-range sound card like the Audigy or the Terratec.
From a pragmatic point of view, the CS 21 is the best speaker set as it has the best power rating/quality/price ratio of this comparative test. The MegaWorks 250D is also a good buy and has a different musical approach, so it is up to you to make a choice between the two of them.
In the cheaper set category (below 100 €) the Inspire T2900 is a fine choice but has a deficiency on the bass frequencies. Without this deficiency it would probably have had a golden award. With such cheap price and satellite quality, it is a shame that Creative Labs made this choice. But if you are not bothered with this bass management, this set is a good choice. The VS4121 suffer from the same problems as it has a very interesting design, but a noisy power supply and a disturbing buzzing sound. The only set which extricates itself from the rest is the 221 with an honourable quality and a low price.
