not the reality
Knowing how, when and why something was altered is very important. It tells you a lot about the people involved, their motivations and even their "voice" as you put it.

I asked my grandparents about some B&W photos of their wedding where their faces looked suspiciously smooth compared to the rest of the image. Apparently they were touched up by hand.
(Not saying that's what has happened here, you could be right and it's a modern edit)

Just if you're interested: there are a tonne of different silicone chemistries.
Single part curing (no mixing needed, cure when exposed to air):
- Acetoxy (emit acetic acid)
- Alkoxy (emit methanol)
- Acetone
- Ketoxime (don't know if this one smells)
Two-part curing (you have to mix the two components, then it starts setting):
- Condensation cure (tin catalyst) cheaper
- Addition cure (platinum catalyst) basically better in every way but more expensive
Yes it looks like it's adjusting the port length. (In plain english: some speaker boxes have an intentional hole in them, if you adjust the length of the pathway that sound takes to exit the box through this hole then you adjust how bassy it sounds).
To add a hollow cavity into the plastic part would immensely complicate the design of the moulds (assuming you try and implement the cavity in the same style & orientation of what gluing that bit of wood in achieves). The plastic shells of this speaker look like they've been designed for two-part moulds, which is the cheapest and simplest way of designing a mould. Any internal cavities of the part would require bits of steel mould to be in the cavity during injection, those pieces then have to be removed somehow and that would be a nightmare. Two part moulds can just be clamped & separated over and over again without snagging on anything.
For the walls of a speaker to reflect sound they need to have a density that is very different to the air inside the chamber. As it turns out basically anything fulfills this criteria, even cardboard makes fine speakers (just don't get it wet or poke holes in it). Plastic vs MDF wouldn't matter here acoustically, both are fine.
Bits of particle board can easily be cut and glued by unskilled workers. For business reasons the injection moulding might be getting done at a different place to the final assembly, and the product manager who wants the speakers properly ported might only be in charge of the latter. IDK.
glue applied likely by a machine
I suspect this would be all human assembly. They'll probably have motorised torque-limited screwdrivers and jigs to hold the parts on during assembly, but still human arms doing the work.
In particular: stuffing the white polyester wadding in would be a PITA for an automated assembly machine. Humans are tolerant of variation and bits of wadding blowing away, pre-programmed movement robots are not.
I'm jealous. Walking height ceilings? Arches???
That (chinook-style solution) only works if both rotors are the same size and speed.
Perhaps Sikorsky's tethers to the ground worked around the problem for that photo anyway. Not sure.
Really, Penfold.
Sounds like they're slowly recovering from an injury and see returning to office as an accomplishment. Take it easy friend, little steps are stronger than big steps.
Every news website is covering it. I think I've spotted most of 10 articles around the place.
The law of well-marketed unreleased goods dictates that this vehicle is not going to meet any of the promises mentioned in the articles. I hope to be proven wrong, but just like video games: don't pre-order, wait for it to come out and be reviewed.
I suspect that you need to think of the 3 B->E voltages as inputs (OR'd with each other) and the C->lowestvoltageE path as the output. All of them are operating in linear mode too, I think one of them is a low-gain follower whilst others have a lot more gain. Maybe.
~~Nope, bottom right and top middle >:D~~
Oh my god I've forgotten what a base is. This transistor is doing my head in.
You can do all sorts of nifty things when you're designing silicon. Including this abomination.

Source: datasheet for LM161, a high speed (20ns delay) moderately high voltage (30V) comparator. I'm going to try and make a discrete version of some bits of it and see how well it works. Maybe not this triple-emitter NPN though, I draw the line at components that require livestock sacrifices.

Two different sizes shown. Each has two inductors (grey bits) stuck to a capacitor (middle) with some metal end caps acting as terminals. There is a third terminal underneath the capacitor. Grid in background is 1mm, pics stolen from LCSC.
I think this taped picture is also really cool (stolen from here):

Location: Sydney, Australia. Found it during bushcare.
The brass barb fitting and the powdery filling suggest some sort of kiln burner to me, but the dark green paint on the outside of the tube looks rather ordinary and not like it has been through high temperatures.
The soft, powdery cemetitious filling has a copper-green tint. Only one end has a hole.
If it were not for the brass barb and coppery fill colour I would assume this is just a bit of structural steel from someone's carport (or similar) that has filled with cement and now been cut to pieces for disposal. But a carport with a barb fitting? WTH?
We find all sorts of garbage in this bushland because it's sandwiched in suburbia. Traditionally it was a dumping ground (mattresses, furniture, asbestos, whole cars) and today still people use it illegally as a dump (mainly building materials and soil). Lots of random materials get deposited by or uncovered by stormwater runoff & floods too. There is no limit to the craziness of what you find here.

There is also the angle of the everyday consumer. Companies seem to get worse after going public. Encouraging companies to go public could have consequences on consumers (and therefore the economy).
