What happens if speaker impedance is lower than amplifier?
When connected to a speaker impedance load that's too low, the amp will begin to get very hot and this can burn out the output transistors as they can't handle the heat caused by trying to supply excessive current to a lower speaker load.
Can speaker impedance be higher than amp?
If the speaker cabinet impedance load is higher than the amplifier rating, e.g., an eight ohm cabinet plugged into an amplifier with a minimum impedance load of four ohms, you're cool. You're not getting the amp's maximum output, but don't panic over it.
Can I put a 16 ohm speaker to 8 ohm amp?
If you connect a 16 ohm speaker to your 8 ohm output transformer the impedance as seen by the power tube plate increases and plate current decreases which can lengthen the lifespan of your power tubes, especially in Class A amps.
Can I use an 8 ohm amp with 4 ohm speakers?
Four-ohm speakers are another story, they can place higher demands on 6- or 8-ohm rated receivers and amps' power reserves, but even those receivers/amps won't run into trouble with 4-ohm speakers, as long as you're not playing music or movies at a very loud volume.
