    Is there much of a difference between an 8 ohm speaker cabinet verses a 4 ohm one? I need to buy a 410 and there are two used Peavey 410's for sale..one that is 4 ohm and the other 8 ohms.

    There isn't much difference. 8ohm will give you more flexability if/when you add another cabinet.

    The lower the total , the more power can be utilized from your amp. For example, a Groove Bass 1200 can deliver 500 watts of power @ 8 ohms, 800 watts @ 4 ohms, and 1200 watts @ 2 ohms. If you plan on having 2 cabs in the near future and/or have a head that can go down to 2 ohms, get the 4 ohm cab.

    The lower the total impedance (ohms), is what I meant to say

    But an amp like the SWR 2004 that says 200@4 and 160@8 Eitherway there isn't much difference. You should have the same volume or tone, right?

    Yep...pretty close, and hardly discernable to the naked ears

    How about an amp that puts out 300 watts into 8 ohms and 500 into 4....will I be able to hear a difference?

    Not really, hardly 3dB.

    You could probably hear a little difference, but not much

    You're welcome...by the way...I know about the cab, but what amp are you running?

    So, in conclusion, one should get an 8ohm cabinet if they plan on changing, upgrading, adding more cabinet.

    Yes, unless the amp you have (or getting real soon) goes down to 2 ohms...then you can safely run either 1 or 2 4 ohm cabs. Most only go down to 4 ohms, so the 8 ohms cabs would do the trick safely.

    You, my friend, can get down to 2 ohms!!! Go for the 4 ohm cab (and then get another one so you can pull that 620 watts outta that sucker!!) :hyper: :hyper:

    Get which ever you want to. Either way you can add at least one more cab, and the wattage difference wont make much of a noticable difference in volume. Test drive them both and see if one is your tone better.
