The real issue is not Watt
Its the topology, at direct clash with interests
Before posting that schema it was pacific ocean )

Indr ,is for me not a troll,he give me new ideas,what you with 5 volt can do.
Thanks Indr.

This in its own way is interesting. Here we have a poster who just denies the facts and figures of reality and holds on to his own totally nonsense stuff.
How do you convince someone like that? I think you cannot. Totally not interested in learning anything, he's just playing and having fun, and that is his right.
And if you can't stay away, ignore list is your friend.
Just hope he is not the doctor if you need an operation 😱

Jan,Belg,the speaker must in combination with the amplifier,what is the problem of this man Indr and his ideas ?

One of the most intriguing science fiction stories in recent times.
indr, in your diy intentions you have overcome all limits, diy'ing not just audio, but also, seems, laws of physics.
Please acknowledge for some naive diyers, that this all was not serious, but just a learning exercise for 7-10 y.o. kids.

Thanks Circlotron. Did you try listen to it? Do you think the design has any use with or without modification?
I think the error from indr comes from not knowing enough about soundlevels and hearing. I think the majority thinks that a 100 watts amp is twice as loud as a 50 watt, so persiving a 0,25 watts class a as a 10 watts is not so far off -even its very incorrect in reality
I know, you're into valves, you know db, and not into nonsense watt war.
Few others are too who might be already enjoyig the sound.
"10w class A sounds way different than 10w ab or chip amp."
That's the only part I'm interested in.
No one listens with watt figures all the time in mind.
Actually never.
Just like in photography, no one minds pesky specs, iso, aperture, film type after, say, one day max.
You better tinker with different mosfets, increase the amp, till it heats voice coil, use all range driver, if possible, get olde alnico ones, yes, they were from times when it was only class A.
And the music, the real thing.
I could not listen just one MMorricone this weekend properly defending my poor amp !
Considering he uses 4 ohm speaker which typically has 3 ohm resistance and a bit of inductance, it is possible for the OP to get ~ 0.6 - 1W which could be loud enough for his needs.
As is, design pass DC current into load, not a good idea for a speaker. Can be used to drive DC motor/fan or LED lighting.
You must just the right amplifier for the speaker and not just the best theoritical amplifier,that’s is a great problem of the theoritical guys.

There is some truth to what you say, the best approach IMHO is to optimize the total chain, from source and amplifiers to driver and listening room. But current speaker driver design does not allow reliable operation with a large DC current.
Thank you. Better for all - especially for beginners who really want to lern something (and who know the mysterical thing called maths).
Beginners can learn something at the beginning of the thread if they want to. If they want to believe all the nonsense that's their problem
Why the Belg? You don't know my nationality, please don't go the way of the personal attacks, too childish.
No problem with indr's ideas, just the nonsense he brings. If someone says that he can take 10W out of a 5V supply into a 4 ohm speaker, how believeable is anything else he says? Has he done what he says he has done? Does he have the stuff he says he has?
I have a problem with people spreading nonsense, and there are a lot of onlookers here who don't realise most of it is.

And that is exactly why I drew him out a bit; to make it clear even to beginners that his ideas are not on solid ground. No problem if anybody wants to copy his examples, just realise that they are not going to give results as good as he claims.
That’s is de great problem between theoritical guys en practical guys.
Your brain work on automatic what you have learn theoritical ,but is that correct ?
I think that’s more informationis ,but we have not the instrument before.
We haven,t not the instrument of dna in audio,my be 100 years later

If everyone would know what is better for them, the world could have been a less chaotic place.
Diy guys are nnt necessarily beginners, certainly not here, armed with theories and advanced components like mosfets.
If an amp paired with exact speaker syastem sounds 10w, what should anyone tout? It sounds like 1w?
That's pure nonsense.
The flaw started long ago, when 500w boom boom stuffs started to flood the market, denouncing quality of class A with quantity of cheap chip amps, more of a selling strategy, with more confusing pmpo labels.
Theorists should have declared purification back then, its way too late now.
People's hearings now set for more and more watts!
And fortunately or unfortunately they are not here !
Class-D H bridge would give 4,5 Wrms/4 Ohm with 6 V accu PSU (in theory) and that is absolute max. without using DC/DC step-up converter.
See attached 2,5 W/4 Ohm Class-D BTL amp at 5 V PSU with only 3 external components. 😉
