One sound effect was wrong (Corsair Sp2500)

Hi, I have had my SP2500's for two days now they sound awrsome, but I was playing a game today and one single sound effect sounded very wrong, like it was muffled.



Now I've gamed for hours on these speakers, and so far I have heard that particular sound effect only once. But everything else sounds perfect.



I'm not sure what I can really try...
