Can I use different ohm speakers?
Conclusion. In a nutshell, while you can mix different ohm speakers you are more likely to get the best sound quality from speakers with equal ratings connected in twos, such as two 4-ohm speakers connected to speaker number 1 on the amp or receiver and two 2-ohm speakers hooked up to speaker number 2.
What happens if you dont match speaker impedance?
Your speakers won’t explode as soon as you switch on the amp. However, if the amplifier isn’t designed to drive speakers with lower impedance (4-ohms, for example), then the amplifier may overheat if you turn the volume up very loud.
Can I use 3 ohm speakers on a 6 ohm amp?

The short answer, yes. The impedance (Ohms) will determine how much current is drawn from the amplifier. It is safer to use a higher impedance on an amplifier than a lower impedance loudspeaker on the same. Two 6 ohm speakers can be connected in parellel on one 3 ohm amplifier channel.
Can you use 6 ohm speakers with an 8 ohms receiver?
Yes, you should not have any issues intermixing speakers rated 6 ohm and 8 ohm. You only get into trouble with wide variations, like 4 ohm and 16 ohm intermixing. Generally, the ohm rating on a speaker describes it’s efficiency, in other words, how much power it takes from an amp to power the speaker.
Can you mix 3 ohm and 4 ohm speakers?
Yes. I just wonder where did you find a 3 ohms speaker. It depends on the power rating of the amplifier and the speaker. In general, yes, it will absolutely work, and there shouldn’t be any problem.
Will 6 ohm speakers work with 8 ohm receiver?

What happens if you run 6 ohm speakers on 8ohm amp?
Can a 4 ohm amp run 6 ohm speakers?
Yes, using a 6 ohm speaker on a 4 ohm output is safe but will result in slightly lower output. If your amplifier puts out 100w at 4 ohm I would expect it to output 75w at 6 ohm. Aurally this would be a reduction of 1.5 db which you would is inaudible.
