Hi. Wonder if anyone could put my mind at rest. I'm no number cruncher at the best of times, and know only this:
That it is better to have a larger amp and smaller speakers when it comes to wattage. (Oh, I do hope that's right!).
If an amp says this: 60W x2 continuous power into 8 ohms / 135W, 190W, 240W IHF dynamic power into 8, 4 & 2 ohms, respectively...
And my speakers say on them: Power handing: 15-100W / Impedance: 4-8
Then is this a compatible match?
I know about amplifiers and speakers varying in actual impedance during operation, but still, just a basic answer is what I'm after here, for peace of mind.
Bearing in mind, the last amp to be driving these speakers simply says 150W on the back. It was a NAD 3225PE and I also have run an old 3020i on them as well.
I'm afraid if I get technical answers here, I won't be able to understand them, so simplest possible terms, please!
So do I need to heed the lower number (15W) on the speaker's wattage, or the higher one (100W)?
"That it is better to have a larger amp and smaller speakers when it comes to wattage. (Oh, I do hope that's right!)."
Most tweeters are destroyed because the amplifier did not have enough clean power to play as loudly, with the speakers' efficiency set, as the owner wanted. That does not mean you require large amounts of power to get loud. It certainly does not imply that large amounts of power will play cleanly at any volume.

The most basic answer is, probably.

Neither. But more to the lower than the higher.

"I thought the NAD 3225PE was something like 30Watts, so how come it says 150W on the back?"
That's the amount of volts/amps the power supply draws from the AC outlet.
