The impedance of a speaker is rated in ohms. You have to match the output of an amplifier to the speakers impedance. Or something like that.

so which i better having more ohms or less???

You just got to match them up, I don't think there's one "best" value.

does not matter, as long as they match. Set your head to the same impedance as the cab you use.

With SS heads, the lower the ohms(resistance to current flowing thru), the more power they will put out. You just shouldn't go lower than the minimum impedance they rate the amp at.

With tube amps, there is an impedance matching output transformer, that matches the circuit to whatever speaker load you are using. With these, you should always match the amps impedance to the speaker(s) impedance to get the highest power rating. Lowering the impedance, or raising it, will both result in power loss, and can damage the transformer if it's a large enough mismatch. With this type of transformer, the higher the ohm setting, ie. matching a 16ohm head to a 16ohm cab, is supposed to give you the best sound, as it's using the most winds from the transformer.

impedance is the resistance to alternating current, or something like that. Regardless, you should try to match them.

I'll have to put the Classic T models on my to-try list. Shame the finish options there are Anachronism Gold, Nuclear Waste and Aged Clown, because in principle the plaintop is right up my alley.

to get ohms, otherwise known as resistance, take your incoming voltage (120 V if it's a standard house plug) and divide it by the amount of amps your amp or speaker is rated for

IE: 120 divide by lets say, 10 amps = 12 ohms

when talking about amps you should probably say amperes so we don't all get confused like i just did

no. that's an oversimplification at best.
