Okay, well-- I'm gunna hope the devs look at this, otherwise I guess I'll have to submit a bug report (which I really wouldn't consider this a bug... just a major annoyance that shouldn't occur.)
Basically, well if you have a decent speaker system (with a subwoofer and whatnot) if say, 3-4 turrets are making the spin-up sound, it is literally deafening-- Sadly, my speakers (like many others) depend on the subwoofer to function. I'm unsure exactly what the problem is, but I think it should be a fairly high priority to get fixed- My reasoning behind this is, well, it makes the game nearly unplayable with above average speakers, I can have the volume on extremely low, then run into the human base, and expect to hear a massive, almost grinding sound come from my speakers.
(As a side note, it really doesn't matter all that much to me, as my headphones will suffice for trem, but I really do think this needs to be addressed)
Thanks for reading. (If there's anything I can do to help, by all means say so.)
