What happens to an amp below 2 ohms?


.
I've been reading some amplifier specs. They rate a particular amp stable down to 2 ohms. What happens if the speaker dips to 1 ohm or below? Does the speaker get damaged, or does the amp clip or turn itself off or get damaged?

Are you saying that people who have electrostatic or ribbon or planar speakers where the load impedance dips below 2 Ohms are not enjoying quality sound & that they are merely reveling in high SPL music environments in their respective homes?????

No, what I am saying is that if those 'electrostatic or ribbon or planar speakers' were higher impedance the owners would be enjoying even better quality sound.

We can look at this from a very basic point of view. If a speaker has a reputation of being 'difficult to drive' due to low impedance, the reason that phrase is used has to do with the fact that the amplifier has a difficult task. Don't think for a minute that there is no price paid for that! The amp simply will not sound as good.

In addition, speaker cables get **critical!** when you are driving lower impedances. With higher impedances the cables are far less critical and can be run longer distances.

ah, I see! Thanks for the clarification.

Ralph, I did not understand this comment - amplifier has a difficult task & the use of phase. Please elaborate. thanks.
Ralph I am a soundlab m2 owner and have been wondering if using Ma1's with zeros would yield the same speaker performance as using the Ma2;my opinion would be the ma2's would control the panels better than the ma1's and result in a better sound;would you agree with that analysis?

correction! this is not an analysis - it's your opinion (as you correctly write at the begin of this sentence)....
Rleff, its a matter of power- in some rooms you have enough power with MA-1s on the big Sound Labs and in some rooms you simply need more. But you would not need ZEROs in any event.

Bombaywalla, the word was 'phrase', not 'phase'...
