Why do speakers improve with more powerful amps?

It's the quality of the signal powering the speakers that would seem to be very important.  A large reservoir of power well designed within an amplifier allows for the frequency demands to be there when you need them.  Presumably a higher powered amplifier would achieve this better than a lower powered amplifier.

Are there other factors that improve a speakers performance when an amplifier offers more power?? And why is this

Dear @jumia  : Speakers does not ask for watts but for current, so watts is useless in your question but manufacturers normally does not gives amp current delivery but watts that has a close relationship in between.

Now, through our audio life normally we can change 2,3 or four times our speakers so to own a high current or high watts amp specs is really favorable. Always is way better the headroom necessary in the amp when the speakers and the SPL we choose need it.

High watts amps does not damage any speaker when low watt amps can do it: clipping and at those SPL your tweeters disappears/destroy.

From my experience, blanket statements should be avoided at all costs.

The fact that "your speakers" and "your amplifier" worked in "your listening space" with "your music", doesn't mean much when you change all the parameters and certainly shouldn't be the basis of a recommendation to someone else.

In my case, the increased power from 50WPC to 200WPC made a significant improvement. My speakers have an efficiency of 85dB.

The correct answer as is often the case is “it depends”. It depends on the overall design of the amp, the speakers used with, how loud one wants to go, how big a room, how far away from the speakers, and yes even the kind of music and recording being listened to.

I think that pretty much covers it.

Not to mention each person’s personal preferences alone might lead them any which way.

In any case it’s always better to have more power than needed than less. That’s called headroom and is a real engineering concept and not just marketing. You can look it up!

Too little power means clipping occurs. Clipping is a signal processing concept that you can also look up and is good sound public enemy #1. Most tube amps and many Class D amps and a few others soft clip which at least makes some clipping listenable but it is still a defect in the reproduction of the sound and should always be viewed as a negative to be avoided.

Any discussion about power without reference to clipping is basically useless. More power can be viewed as an “insurance policy” to avoid clipping.

Case closed, right?

@jumia -- "So why the hell do people buy inefficient speakers?"

Simple, I like the way my Ohms (main system) and Spendors (2nd system) sound. I prefer them to the many more sensitive speakers I've heard over the years.

I'm not here to impress you or anyone else, nor to change anyone's mind about their audio preferences.  While it is fun to talk about our hobby, there are tons of opinions out there but it is up to each individual to decide what works for them.
