Meanwhile, in the real world, we have to deal with compromise. What you call bad design, others call a bargain. Not every component is designed for every workload; even bridges are designed with load assumptions. It is not economically viable to make everything to the greatest durability possible. If it is important to you that every single thing be as min/max'ed as possible, you are welcome to find a manufacturer that obliges such tastes and fork over a premium for it.
He is not saying that everything should be designed for maximum durability. He is saying that things should be designed so that they don't break the first itme something a little unusual happens. A bridge which collapses under a bumper-to-bumper traffic jam is defective. A laptop computer sound system which breaks if certain sounds are played with the volume all the way up is also defective. (After all, laptops are frequently operated with he volumn all the way up.) Here Dell is claiming that VLC filtered the sound in a certain way and that their speakers are not designed to play that sound. That is just silly. It is as silly as a highway bridge designer who says that he didn't know that his bridge was suppose to be able to handle bumper-to-bumper traffic.
That is asinine. It is the speaker that draws power; it is not up to some "rating" to determine how much power is given to the speaker. If you plug a 200W speaker into a 100W amplifier and open the amplifier up to full, that 200W speaker will try to draw 200 watts of power, likely overwhelming and destroying the amplifier.
Actually, no, higher wattage speakers do not automatically draw more power. The power rating on a speaker specifies the amount of power which the amplier can pump through the speaker without damaging it. How much power actually goes into the speaker is determined by the number of volts which the amplifier puts on the line and the impediance of the speaker (which is generally 4 or 8 ohms). With the volume control set to zero there are zero volts on the line and the speaker is consuming zero power, no matter what its rating. As we raise the volume the voltage rises and the speaker starts consuming power and producing sound. As we raise the volume the amplifier will get to a point where it is producing the maximum voltage of which it is physically capable. That may be less than the speaker could endure, but so what?
Saying that speakers with a too-high power rating will blow an amplifier is like saying that tires with a too-high speed rating will cause a car to go too fast. How fast the car goes depends on how strong the engine is and how much you press the gas pedal, not no how strongly the tires are constructed.
