Graylion wrote:In a similar vein here's a question for an expert (i.e. Didier!) Amplifier output power and actual volume are on a logarithmic scale whereby the apparent volume, for instance, only doubles when the power is increased by a factor of 10. Meaning that, all things being equal in the speaker department, a 1000 Watt amp will only sound twice as loud as a 100 Watt amp.
The question: will two 100 watt amps sound twice as loud as one?
Logic says they will, but what has that got to do with anything?

Graylion wrote:Thanks Didier - yes, I know about speaker sensitivity but the question is simply about comparative volume using two identical combo amps with identical speakers - as I said, logic tells you that two seperate amps will sound twice as loud as one!
Cheers, Lionel
