I play mostly cod4 online and as anyone who has played fps games online knows, hearing where the enemy is is key (especially footsteps). I've read most of the gaming headsets thread, but do not want to buy expensive headphones right now. I am a bit of a idiot so please bear with me. i have heard that keeping the sub woofer to a minimum is a big help, which makes sense as it can cover up subtle noises. On the receiver, what should i do for +/- treble/bass ? Will anything help with hearing people. Obviously cranking the volume helps but i wouldnt mind a better calibrated speaker set up. In case it matters, i have a sr5001 Marantz receiver and Klipsch speakers. Any help would be greatly appreciated!
