it looks like a pretty good sub all the info on it looks pretty good 20hz is pretty low for a 4 ohm subwoofer it would be a better sub if it were 2 ohms but yes its a decent sub should give u some pretty deep bass if its in the right box.
im getting out of this argument im not saying ur wrong and im not saying im right all i said that started this whole thing is the sub would be better if it were 2 ohms and that is true no matter wut way u look at it
no its not. cuz my existing amp puts out 200rms @ 4 ohms. thats all that sub can take. if it were 2 ohms then my amp would probly f*ck it up.
"all i said that started this whole thing is the sub would be better if it were 2 ohms and that is true no matter wut way u look at it" No, that isn't true. I agree that a sub must be matched to it's amplifier for the proper power requirement. I disagree that this is best done at 2 ohms, the only benefit in that area is that you save money. An amplifier will have lower distortion, more headroom, better damping, higher signal to noise, and overall better SQ when running a higher impedance. For SQ, 4 ohms would win the day. The key is giving the sub it's required power, and this can be done at any impedance if you match it right.
