That is why I just don't like the USB-Medusa. I got the one with the amplifier and it really beats the USB-Version in many regards. But both versions lack the basses I know from my headset. When I start the engines with my stereo-headset, it really sounds like a starting engine. No matter what I set my X-Fi and my Medusa to, the fact that frequency-band starts at 50Hz simply stops any fun for me. Using that headset, I can understand why people complain about the sound in IL2
My stereo-headset starts at 8Hz and has pretty much beat at that low frequency. Awesome, especially when flying a P47 and firing all guns.
