All right, so we don't normally do audio video representations because in no way do they capture what a system is really doing. Uh, you can drop a soup can on the ground and shoot off a gun, and the phone is going to perceive that audio is the same. You have a stereo doing 130 decibels, which is ear bleedingly loud.
So jet taking off from aircraft carrier and the phone won't differentiate it between a moderately loud stereo. So we don't normally do this, but we're going to do this just to show you the value of what an enclosure does and what it doesn't do. So what you have here is an eight inch driver in an enclosure that has a reasonable amount of airspace for it.
So I'm going to show you what happens when this thing goes in and out of the enclosure. This is very similar to whether this is mounted in a flat abs plate or, you know, we've seen plates that are mounted in the roofs of a defender where there's no enclosure behind it, speaker in a plate.
So this is what that speaker sounds like mounted in those type of scenarios.
So as you can see, all the low end frequency is lost. It's cancelling itself. Um, the same thing happens, like in the KRX, for example. They've got a six and a half in the door. We love door locations, but they made a big mistake. In this position right about here, you have the hinge of the door.
So the same thing is happening. The sound is escaping from the back of the speaker, reaching the front of the speaker, and it's cancelling out all of that bass. It's also a six and a half, which we don't love. Six and a half's, but you're running in the same problem.
So I'm going to show you by just cracking just a corner of this, that represents what's happened in the KRX.
So people try to solve this problem, they'll try to put foam baffles behind the speakers. That does solve the problem with the sound escaping from the back to the front of the speaker, but then that chokes off any airspace. What makes an optimal, ideal enclosure one is its location, that it's on access to your ears.
It's not pointing down at the top of your head, it's reaching ears as it's supposed to, that it's an enclosure that has airspace, functional airspace reasonable relative to the speaker, that it's dense, it's not a thin piece of plastic. You're not getting flex and movement of the box instead of sound coming forward.
Which is what happens in your typical blow mold, uh, your typical abs enclosures. That enclosure is flexing. The sound's not going this way, it's going backwards. Um, another thing that's very, very important is just the raw horsepower of speaker size. So this can do something amazing in a car.
In a six and a half. In a car, you've got sound reflection, sound pressure. A, uh, six and a half is a great speaker, but in this arena, this speaker is less than half the size. Uh, this makes a big, big difference in total output what this can do compared to this.
Same thing with the subwoofer. You can have the most amazing subwoofer in a band pass box in your trunk. You take that same box out, set it on the driveway. That subwoofer does now almost nothing. Um, that has a lot to do with the environment that it's in. That's open air.
So side by sides being open air, you know, if you can do twelve s, you want twelve s, you need proper airspace behind it. And we don't touch six and a half's. You know, everything we do is based on the eight inch. Because in this world, it makes all the difference in the world.
All right, so we have a completely different production method that allows us to get far larger enclosures out of a material that's far denser. Uh, for speaker performance. You can see here in the can, AMX three, you've got a twelve inch, uh, compared to what is a typical ten across the board.
Almost all the brands look the same as a solution for this car. But you can see that gigantic difference between airspace between these two. And you have the surface area of a twelve versus, you know, a ten. So makes a big, big difference. What also makes a difference is what that enclosure is made out of.
Is it internally supported? None of the blow molds are. We do. On our larger enclosures, there's structures that bind the front and back and sides together, so there's not as much box flex. The material itself is more dense. But coming back to what we have here, you know, this is a kickpod example.
What we want to show is the difference between, you know, an eight inch and a six and a half. You'll see competitors kicks. For example, for this talon, where you'll have this speaker, uh, in an enclosure that I don't think you could pour a can of soda in behind it.
Tiny, tiny. And it's thin blown molds, um, they just don't work. Uh, whereas if you look at this enclosure, I mean, we grab every bit of airspace that is possible in any and all of our cars for optimal performance. That airspace, the rigidity of this enclosure, the size of the speaker, all of these things add up for performance that can't be touched, and certainly not in a little six and a half in small airspace.
