Quick question.
I have a speaker which can be run at 4 or 8 Ohm. Which is better? I presume the lower load puts the amplifier under a little extra stress when trying to drive the speakers a bit like the american 1 Ohm monsters we sometimes hear about. My amp has 4 and 8 Ohm taps, I've been running 8 ohm. I also presume your all going to say, "Whatever sounds best".
Ta.

Whatever measures best.  |

Whatever measures best. I somehow expected that Jerry! |

You have a speaker with switches to alter the loads it presents to the amp? That's a new one.

I think you have that back to front Andy. The speaker provides the load to the amplifier, not the other way around.
If you have 4 and 8 ohm taps they are to provide the correct reflected impedance to the output valves for most efficient operation.
What is the actual impedance of your Celestions?

Thanks Alan that’s explained things perfectly

Or what's the minimum peak impedance.

Its pussy unless it's nomial 4ohm dipping to 2.5 @ 50Hz with sens around 85 speakers for men with large hairy spherical objects.
Conversely a quality 100Wrms with 30+ amps of current will more than suffice imho
