Question, why do some amps double power from...


8 to 4 ohms and others don't?

Is it because their power supply rails are not quite high enough in voltage? Is it because they don't have enough reserve storage in their caps? Are there some other factors I have missed.

Thanks,

Thank you for your responses.

The reason I ask is that I intend to drive a pair of Thiel CS3.6's and they spend a lot of time around 2.3 ohms. It has been said that the they are driven best by amps that double their power into 4 ohms. I guess they are real current hogs.

I just purchased an amp that does 200w into 8 and 350w into 4. Not quite up to snuff considering the doubling rule and I'm just wondering if it would be possible to tweak the amp into the doubling range. I'm always tinkering with something. Perhaps I could add stiffening caps and a larger transformer. Of course I'll wait to see how it works without any mods first but besides always tinkering I'm always thinking!

Thank you,
Ron
