Reply to comment by FallofftheMap in LG Display’s ‘invisible’ speaker brings sound to any surface in your car by MicroSofty88
A speaker is an insignificant intrusion into a crumple zone and no engineer cares about a speaker going into your knee. Speakers themselves are already pretty thin to the point where if it's going to happen, you've got larger issues based on the fact that a 6.5" speaker is around 2.5" deep, held together by paper, and weighs around 2lb.
As for weight, these will save at most 35lbs (assuming a heavy set of speakers at 50lbs total and the fact that these are only 70% lighter) on a 2000-6000lb vehicle.
If anything, these would get put into flat panel TVs, but a car? There's too much dead space behind nearly every panel to justify it.
Finally, keep in mind, we've had flat panel speakers for decades, and this isn't the first article to proclaim their use in cars.

So are these speakers 35 or 2 pounds? Lol holy about shit what a range

Well, the key word in my post was *set* as in multiple speakers.
I also assumed a large *set* of speakers and assumed a heavier than average speaker to show that the weight savings, even at the high end, is insignificant in terms of total vehicle weight.

Nice math. It really works in your favor

No, it works in their favor.
But I am curious how you think it works in mine, please explain

You're arguing points that relate to the size of the speakers while disregarding the same points to contradict yourself

Want to be more specific?

About which part? Lol you can read right?

Yes, but your first message indicated you have issues with reading, which is why I want to know what specific statement you are misreading this time.
My overall point was that if you were to replace 50lbs of traditional speakers with these new flat ones, you'd only save 35lbs, which is miniscule compared to the overall vehicle weight.
If you assume 20lbs of speakers replaced, it's even less weight saved.

Think forward. Speakers complicate aerodynamics, sound proofing, and add weight where you do not want weight. Cars are just drones that don’t know how to fly yet. We’ll all want to be wrapped in the most aerodynamic space and weight conscious vehicles possible, because it’s going to be a balance between comfort, range, and economics.
Weight is the only valid argument here, and even then you're talking a miniscule fraction of the total vehicle's weight. As long as crumple zones are mandated, there will always be room for speakers (think between the outer and inner panels of doors. Soundproofing is more for road/vehicle noise and will tend to be on the outer panel of any body section.
I couldn’t disagree more. Weight and space required for things like speakers complicate an engineer’s job, requiring compromises. Crumple zones require empty space to crumple. They don’t work properly if they smash a speaker into your kneecap. There are huge advantages to minimizing the space required by the most space wasteful components of vehicles, and speakers are obvious low hanging fruit

Like I needed to waste my time doing this.

Wait, so you took both sides of the conversation and attributed them both to me?
