I pass my pc through my Yamaha AX-592 2X100 Watts at 8 ohms with sub drive and in my active small but good 125 watts 10'' woofer and this isounds awesome
lol any frequency range can basically tear up hearing though i may find it that the worse at it are 300Hz-9KHz our ears dont really pick up sound in perfect perception but it gets filtered into perception but i may suspect that around a midrange bandwidth is where our ears are most vurnable to damage though really if you must know whenever you feel discomfort in your ears they may be recieving damage
and also my 10" right now is only hooked up at no more than .75watts rms per coil and i could hear those rumbling lows so heavy it feels like enough to boast about :3 even if atm im only making 88dB max in bass and the fullranges hooked up to would make about 110dB according to specs in this set up but make that 104 im running a 6dB bass boost on a gpx hc221b's main unit and its hifi a bit but pitiful power and the speakers were of a relatively low clarity but maybe average or above for 2.5s :3
