These are class D audio amplifiers. They do not dissipate any notable amount of power compared to class A/B/AB amplifiers which are traditionally used in audio amplifiers as they never operate in the "linear region". The output is just switched on and off very quickly and filtered.

The IR4301 in that series of chips can drive 160W into 4 ohms without a heatsink at all, all day every day and is merely 5x6mm in size. We've come a looooong way in audio design from big bulky amplifiers. Most of the mass now is the power supplies.

Apropos of nothing I have a tiny class d kinter amp driving an old pair of Apple Pro speakers (the ones that shipped with the G4 iMac and some of the Powermacs) wired up to a raspberry pi zero w running shairport sync to turn them into airplay2 speakers. They sound amazing, and the amp sips power and doesnt run hot.

Bingo! Apple's problem with the first HomePod was that it had so much that they had no clear upgrade path. With this version, they can introduce iterative updates, making each version contain things that are the "best we've ever had in a HomePod."
I don’t think that home audio is a category that chases updates…

Most people buy the thing and it works for years and years and years.
 
Why not just buy a Sonos which has great sounds and is compatible with multiple platforms.
Fair question, but Apple does have the upper hand with the small details in their devices, such as how simple it is to pair with AirPods, waaaay better than traditional Bluetooth devices. I live in the Apple ecosystem and was happy to order the new Homepod this morning. I have a HomePod Mini downstairs and this will replace the old 2.1 system I have in the living room connected to my Mac Mini giving me Siri in the living room (the kids love being able to pick songs and change volume on the HomePod Mini).
 
I still struggle with the design of an omnidirectional speaker array in a device that has to be plugged into a wall
It is designed to bounce sound off the wall behind it. It analyses its own real-world output and makes adjustments to use that reflected sound intentionally as part of its sound profile. They spent quite a bit of time talking about the computational power that goes into this effect when the OG was released, and they did comment on it with the new one as well. The mini doesn't do this, just big brother.
 
The hardware and sound coming out of that little thing is really good. Too bad the software integration with SIRI is just absolutely atrocious. After all these updates it has not gotten any better. Just worse.

I don’t disagree but it’s Apple we’re talking about. They need a clear upgrade path for all products, to maintain those near or above 40% margins.

has to be ? Are you implying a location constrain? Yes it’s a common for outlets to be in a wall, but also floors, and they make these things called extension cords, so I struggle with understanding your point.

They haven’t updated the AirTags yet. Nor some of their chargers. Apple does a few, not many, products that appear to be viewed more like appliances with longer lifespans.

I suspect they’re more interested in attracting new buyers over driving update cycles when it comes to their speakers.

AirTags are an accessory, not a product. That’s a very important distinction.

I know it’s a marketing distinction, but I don’t think smart speakers are the type of device you update unless there’s a must have feature. These already sound great, so I’m not sure any “smart” features that could be refund or added would really be a compelling reason for consumers to upgrade. We may see a few updates in the next couple of years to further reduce costs (hence enticing people like me who at the right price would absolutely pick one up). I can’t imagine Apple considers an upgrade cycle anything comparable to other product categories. I can see these having unusually long lifespans especially in the older demographic I imagine these are actually being bought by.

I suspect they’re not quite sure what they want to do with these speakers but they don’t think they can afford to not be part of the smart home market, which despite its current flaws is definitely a growth market mid to long term.
 
How accurate is the temp and humidity sensor? Does it work as well as standalone instruments?

It’s in an electrical device that uses a heat sink…. So my tentative guess is “no”… at least if the device is actually in use.

But apparently the amp doesn’t get that hot, so it might still be useful for general measurements.

I’m pretty sure that he meant most people will likely sit one on a shelf or a mantlepiece or on the floor so he is saying that it’s a shame half of the sound is going to be directed into the wall or carpet rather than put out into the room like regular front facing conic loudspeakers do, which will affect sound clarity.

What percentage of people are going to place one in the centre of a room and string an extension cord to it?

If not, then what percentage of people actually have floor mounted power sockets or ceiling ones for that matter?

I really feel that people are purposefully trying to misunderstand others’ comments and score points rather than just give straightforward answers to what appear to be honest questions or opinions.

Is Siri faster? I tell my HomePod to pause the music and it does so…5 seconds later.

Some of us have outlets that are not in a wall. Countertop/islands for example. Also I would assume the chip takes advantage of reflections off a wall to create more soundstage.
