Wow that's a lot of amps/drivers
I'd like to hear one like this as it has 3 eyes.

The Beolab 90 is a very serious and superbly good 'speaker (I've heard them a few times). Mind you, at £69k, it needs to be!Wow that's a lot of amps/drivers
how will efficient class d stop countries over fishing?Can someone explain why some class d amps have a higher rated output than their power consumption I've never understood that.
We may have inadvertantly solved the climate crisis!

Not quite correct, it's the max peak power the amp draws which will only happen at switch-on when the caps are being charged up.No need to over complicate this. The power shown by the manufacturer is the absolute maximum power the amp could draw if running continuously at max output. It's information mainly there for safety considerations. Virtually no user is ever going to run at max power. Most amps would have cut off after a short while in any event.
Also, consider your speaker's sensitivity (not efficiency as often erroneously quoted on this forum and elsewhere). Let's say it's 88db/w/m. That means that one speaker will produce a sound level of 88db at a distance of 1m for an input power of 1W. Now go away and google what 88db sounds like! It's loud. OK, there are dynamic peaks to consider, but you can see that your amp is only likely to need an output of a watt or two. If the amp outputs 3W, and is 33.3% efficient (i.e only 33.3% of input power is available as output power; efficiencies are always ratios [such as percentage]) then the amp requires 9W of input power to produce 3W of output power. This is very much broad brush, but it does explain tne basics.
It reminds me of the micro system I saw in Asda years ago. It had stickers all over it proclaiming its maximum TWENTY watts of mighty output power.if you can get more power out than you put in, then the planet is saved [emoji4]
I think you are incorrect in that assertion. Please think about it and perhaps read the below, particularly the section in "AC Power Consumption"Not quite correct, it's the max peak power the amp draws which will only happen at switch-on when the caps are being charged up.
That's not the climate crisis that's overpopulation and industrialisation.how will efficient class d stop countries over fishing?
I think you'll find its more of an issue than you realiseThat's not the climate crisis that's overpopulation and industrialisation.how will efficient class d stop countries over fishing?
No, sadly the rocketroberts assertion is flawed.I think you are incorrect in that assertion. Please think about it and perhaps read the below, particularly the section in "AC Power Consumption"

"AC Power Consumption: On the back of many amplifiers you may see a label that shows (for example) "1000 watts". This is NOT the output power capability of the amplifier. This is (in almost all cases) the amount of AC power that the amplifier requires from the 120 VAC wall socket for nominal operation at full output using normal music signals. The amplifier's output power must always be less than this AC power requirement specification, because the amplifier cannot deliver more (or even as much ) power that it takes from the wall socket. All amplifiers generate heat to some degree, this is basically wasted electrical energy. Typically, if an amplifier takes 1000 watts from the wall, it might have a power rating of approximately 300 watts per channel (it really depends on the class of the amplifier's circuit class). I see vintage amplifiers on eBay all the time... and those who are offering them for sale (who admit they know little or nothing about amplifiers) often make the mistake of listing the output power of the amplifier by stating the power requirement that is listed on the back of the amp."
