    Sub Impedence (Ohm buzinesS)

    The only difference I have seen in the sub impedence so far is that it takes a more powerful amp to power a sub wired at a higher impedence. What is the sq or spl difference, or any difference if you wire them at a higher or lower impedence?

    no difference in sq, if u wanna look at it from this perspective, the wattage will be increased if the impedance is lower, so u can say it has an effect on the spl if u want, but i'd rather not.

    so why don't they make all the woofers at the least ohm possible so we don't have to buy huge *** amps to power them? Oh well... So there's no difference?

    They make subs with different impedences for more flexability in the installation. If all subs were 2 ohms for example, not all amps would be able to run them without overheating. Not all poeple are interested in running their equipment as hard as possible. A higher impedence results in cooler operation whcih results in improved SQ, amp/sub life, power consumption, and efficiency. These aren't the only reasons, I'm just too tired to think right now - natem33
