I recently received a CM Storm Sirus S 5.1. Currently its awesome, I love it. But whenever I test my headphones, I always notice the Sub woofer doesn't play like a sub woofer that I'm used too. It sounds low, it doesn't sound good as well, feels underwhelming nor does it shake my head or really sound bassy. I realise youtube and most music goes by stereo but bare with me. I don't have many test for it, but when playing games like BF4, turning down my Center volume, rear and front volumes, leaving only my sub-woofer up high. Any grenades or explosions, or any sounds that go through it is very low, and almost virtually unnoticeable, especially if I have everything else up. Is that a problem?
