...low impedance of 2 ohms. Would this be a problem for most amps?
It can be a problem. My rule is that if the loudspeaker gets into the 2 ohm range I would want to match that with a very robust amp that boasts about its low impedance performance.
Amplifier stability with very low impedance, high efficiency mid/tweeter section???
I've been looking for this information everywhere but can't seem to find a clear cut answer. I understand that a very low minimum impedance like 2Ohms is a very difficult task for most amplifiers to drive and may even damage it. But it's also my understanding that this is a current, not a voltage problem. In other words, say we had an MTM speaker that was used ONLY as a midrange from 200hz up, so it wouldn't have to play bass where most current is required. And say it also has a very high efficiency of 97db but also a very low impedance of 2 ohms. Would this be a problem for most amps? Could it damage the speakers? I'm thinking no since the amplifier wouldn't have to put out much voltage or current to output sufficient SPL. But what's the actual answer????
