Confused

Hi all,

If an amp is advertised as having a 4 ohm or 8 ohm version what does that mean?


Thanks in advance

An amp won't be advertised as having a 4 ohm or an 8 ohm version... a cabinet might/will!

'If' it is the latter (ie a cab) then a 4 ohm cab will get the most out of your amp (theoretically it will get 200w out of a 200w amp BUT that is not the real world situation nor is it the deciding factor when getting a cab) BUT you generally wouldn't be able to add another cab, whereas an 8 ohm cab on the other hand will get about 2/3 of the wattage out of your amp (again... theoretically) but you CAN add another 8 ohm cab at a later date.

Tbh there are so many variables in your question that it would be easier if you said what amp you already have and what cab you were considering getting.

Is this a combo? Usually amps have a minimum impedance, typically 4 ohms, and you're ok using it with any combination of speakers as long as the total impedance is above the stated minimum.

If it's a combo, maybe it's supplied with a choice of speaker impedances because it doesn't have the option of an extension speaker?

Sorry I shouldve been clearer = its a cab thats advertised...

ive had issues with impedence too

thankfully the BC boys have sorted that out hahahaha.

I actually fancy 2 350-400watt 8ohme cabs to run with ma 600watt head to get max output.

hope santa is listening

I put the question forwards a few months back about cab ohmage & it makes more sense in the long run to go for 8 ohm cabs rather than 4 ohm ones (depending on what you're planning).
If you want just one cab and don't want to expand on it or are running an amp that will handle a 2 ohm load, then 4 ohm cabs will get all the power from your amp.
If you want to have the choice of 1 or 2 cabs with your amp (or 4 if you can run to 2 ohms) then 8 ohm cabs make sense there.
The difference in a 4 ohm & an 8 ohm cab of the same model (db wise) apparently is not that much but running two 8 ohm versions is louder & clearer than the one 4 ohm version.
