4 ohm speakers, 2, 4 or 8 ohm taps on amps


My speakers are 4 Ohm (Innersound ISIS) and the amp I use for the panels (Sonic Frontiers Power 2) has 2, 4 and 8 Ohm taps available. I currently have it set at 4 Ohm, made sense to me. A few people have suggested I change to the 2 Ohm tap "just to be safe"

Comments and does it make a difference?

leave it on four ohms it will go down to two ohms on the four ohm taps. remember ther are alot of people out ther that dont know ther elbow from there as-
At least what have you done? I've the same question with my Sonic Frontiers Power 2 and my Kef 205 Reference.

Difference Between 1 Ohm Or 4 Ohms

A voice coil is present in every speaker and subwoofer, this device basically offers the electrical resistance which resisting property we call is impedance. As the speaker’s impedance declines, it becomes very easy for the amplifier to deliver power to it.

So, technically considering the difference lies between 1 ohm and 4 ohms is only about the resistance of a speaker’s voice coil offers to the audio current provided by amplifier. The main reason for overheating the amplifier is when resistance is too low that power supply increases greatly than its capability to manage.

Make clear in your mind, if you are thinking of connecting a 4-ohm speaker with a 4-ohm amplifier you are totally wrong. Finding a perfect matching is highly recommended to meet your desired requirements like a 4-ohm speaker can be connected to a 1-ohm amplifier. It is the only way your loudspeaker will not handle the amplifiers full power output.

Another aspect to be very clear, one should be very careful and connecting while connecting the 1-ohm speaker with a 4-ohm amplifier, the amplifier will be overloaded to be even over burned.
