Amplifier that can run both 4 and 8 ohms speakers, can it run 6 ohms speakers

[soundsky]

4 ohms - 130w
8 ohms - 90w

If it can, will 6 ohms be 110w?

Roughly, and close enough not to worry about.

What you need to understand is that the quoted impedance figure for a speaker is nominal.
During use, the impedance seen by the amplifier varies.
An eight ohm speaker, for example, for some of the time will be 6 ohms, it might even briefly dip below 4 ohms.
If your quoted wattages are true for 4 and 8 ohms, then all you can say for sure is that, for the time when the impedance hits 6 ohms, the wattage will be somewhere between 90-130W.

You ask if the amp can run 6 ohms.
If any amp can happily run 4 ohms, then you can be sure it will run 6.

Thank you 😊 Do you know regarding the Whaferdale Denton 85th Anniversary that has a minimum impedance of 3.8 ohms, if that's ok with the same amplifier (Teac AX-505).

I would say it would not be an issue.

Note the word 'minimum' there.
A speaker with a 'nominal' impedance of 6 ohms will, quite possibly dip as low as the Wharfedale.......it's just that you haven't been given the minimum impedance figure for the 6 ohms 'nominal' speaker.

My answer is the same as I said in ŷour very similar question here…

Primare I15, 60w 8 ohms, 100w 4 ohms, can it run 6 ohms speakers?

Thinking about the JBL L52 Classic. Edit: Oh, they are 4 ohms. Question still stands. Recommend amplifier watt is 10-75, will 100 watt be too much?

Too true. The perfect example were my RS6s. Nominal impedance is quoted 6 ohms but it could dip to about 2.5 ohms (IIRC). Shouldn't be a problem unless the amp is low powered.

Shouldn't have an issue.
