Clipping... So, is it even possible to damage these speakers with this amp?

There are 2 ways to destroy a speaker with an amp, but both will give warnings before you break the speaker, due to distorted sound.

1 overdriving the amp so it shorts and send dc to the voicecoil, that start melting and/or burning.
2 overdriving the speaker that it goes in overexecursion, so the cone rips appart.

But if you listen to the amp and are a bit aware of the sound, you will notice it's to loud long before you get at one of both scenario's. And your amp may be protected against overloading it (scenario 1) as many are today.

About your specific speaker or amp, i know to little to tell specific. But just listen and don't drive it into distortion and you're quiet safe.

Thanks.
Hopefully scenario no.1 is not possible due to the Topping having protection circuitry, such that it will shut down first.

I am assuming that no.2 should not actually be possible due to the power handling of the speakers. (I attached the specifications and later complete manual for the speakers in post no.12)

One thing that I am unsure about is how easy it is to notice the onset of clipping. ie. When the amp is starting to run out of power, but before it sounds obviously bad.
(I realise that this won't actually damage speakers but it's the main reason I wish amps had clipping indicators!)

I currently have no worries regarding this as I am using the combination in a relatively small space at the moment. However if I ever decide to use this combination in a larger space or outside, I would like to be aware of potential issues and risks.

As stated previously I have more powerful amplifiers available if needed anyway. Just like to fully understand what's going on.

Clipping will increase power to the speaker (square waves of the same peak voltage have higher average power than sine waves) and shift the distortion to higher harmonics that can damage tweeters. Article here: https://www.audiosciencereview.com/forum/index.php?threads/clipping-101.7164/

It is also possible to destroy a speaker by simply over powering it even without mechanical (cone/surround) destruction by simply exceeding the thermal limits of the voice coil. The speaker will usually begin distorting in that case, and output drop, as the voice coil overheats (and overheats the magnet). Worst-case the voice coil wire's insulation fails and results in that burning speaker smell many of us remember (not fondly). That can happen even if the signal from the amplifier is perfectly clean but just too large for the speaker to handle.

None of that appears to apply in your case.

There is also the scenario where the amplifier's protection (if present) fails, output transistors short, and apply the power supply voltage directly to the speaker. That usually destroys woofers as the other drivers generally have capacitors that block DC as part of the crossover circuit. Early (and some later) Phase Linear amplifiers were (in)famous for doing exactly that. Most modern amplifiers have built-in protection to prevent that. Some better than others...

Thanks!

I think that I have finally got a grasp of the various factors, risks and consequences involved. I now feel pretty confident that I am not going to do anything stupid or risky to my equipment. Hopefully my hearing too!

Looks like the Mini 300 should be ample for these speakers. So unless I put them in a bigger space, there's really no need for anything bigger. All good.
Thanks again.
