I have a pair of 3 way floor standing speakers, on the back of the speaker cabinets it says they are: 180 watts, Impedence 8 ohm, Sensitivity 92 dB, Frequency 35hz- 25Khz. But inside on the back of the speaker cones it says 6 ohm are my speakers 6 or 8 ohm, i'm upgrading to a new amp what should i buy a 6 ohm or 8 ohm amp
The real impedance varies and it can be different from the individual speakers due to the crossover. Furthermore, 8 ohms can mean it varies both above and below 8 ohms, but it typically means you can treat it like it were 8 ohms.
Thank you, would there be any difference in the speaker perfomance with either a 8 ohm amp or a 6 ohm amp
You should buy 4 ohm capable amp. That way you do not have to worry if it can drive it. Besides, you may have different speakers in the future.
Listed speakers impedance in the spec as one number is basically rough estimate. Because in reality, impedance changes accross the frequencies. It can dip pretty low even in 8 ohm speaker. On the other hand it can go high to tens of ohms.

I'm looking at buying an amp where i can set the impedence to either 8,6, or 4 ohms would that be the way to go
As others have indicated there are several factors contributing to a speakers nominal impedance. A fact often overlooked is that driver characteristics are measured in free air. Everything changes once the driver is in a cabinet. This is the likely reason a 6ohm woofer is rated at 8ohms when inside a specific cabinet.

Sure, buy a good tube amp with multiple output tabs. Used to be common in McIntosh.
otherwise its useless 🙂
what exact model of the speakers you have? maybe there is impedance curve on stereophile web page
Just like AllenB said, in 3way speaker, this is mostly depending on the crossover.
I used to have Technics integrated amp which supposedly adjusted its power supply voltage based on the impedance of the speakers. I bought it because of beautiful blue fluorescent peak meter/ output power indicator. Nice to look at. And it was supposed to have 0.007% distortion. Pity it sounded like crap.
Every amp performs better when its loaded with higher impedance speakers. Just look at the distortion measurements on stereophile web, its pretty obvious. If you have amp capable of 4 ohm load, it makes more power, but distortion is higher.

Probably. Regardless, there is a plethora of big box home theatre subwoofers marked as 3 ohms in the specs, and on the cabinet but have a 4 ohm driver inside.
Subwoofer is not 3way speaker with complex crossover. I am not sure what are you trying to say. However, i have no problem with your statement about subwoofer.
Thread starter, who is yet to reveal amp he is buying with three outputs for 4, 6 and 8 ohm speakers, was asking about his 3way speakers, yet not revealed. At least not to me.

1) tell us brand and model, it should have been clerly stated on the first post.
2) do us and yourself a favour and measure the DC resistance of your cabinets.
Remember to short meter probes first to read probe and cable own resistance and substract that from displayed value.
