How This Speaker Broke Physics.

This

speaker

breaks the laws of

physics

, but before we can appreciate how special it really is, we first have to learn a little more about how

speaker

s actually work. Have I ever wondered why some speakers are Bassy and others are not? I know it's a strange question. but stay with me when we think of things in nature that produce a lot of bass, we think of big things with mass like a volcano, an avalanche, or a whale. The same goes for the speakers,

this

high volume microphone monitor and

this

bang and olon beosound. explore has the same size, about the same weight, but totally different bass responses, so why are some speakers bass?

Let's look at this, the Yamaha hs5, a classic studio monitor, this is what we call a two-way speaker, which means that this speaker is actually two. Speakers Up here we have what's called a tweeter that handles the high frequencies and down here we have a speaker that handles everything else except the subbase and I mean the actual low frequencies, we're going to need something like this, this is a subwoofer and this It's what you need. see in places where you need a base to really fill a room. I'm talking about movie theaters. I'm talking about concert halls, even like some crazy home theater setups.

This is the Genel X 10 inch subwoofer and although the size is not really like the whole story. A large cabinet like this will definitely help you get a lot of base, but if size isn't the whole story, what makes a good speaker in the 1960s? Engineers were starting to ask this question themselves, specifically engineers at a company called KLH, now eventually KLH co-founder Joseph Anton Hoffman came up with something we now call Hoffman's iron law. It's not exactly a law of

physics

, it's more of a vague description of some of the physical properties of air, but it can be very useful in explaining why some speakers are Bassy and others are not, here's the gist: a speaker can be small, one speaker can be loud and one speaker can be Bassy, ​​but it can't be all three, you have to choose two so it can be small. and Bassy but uses a ton of power like the dvla fan or it can be small and efficient but not get much Bas as an echo point, it just can't be all three and that's kind of the nail in the coffin for Bluetooth speakers, TRUE?

I mean Bluetooth speakers, they have to be small so they are portable, they have to be efficient so they can make noise without wasting battery life and they have to be low because that's what makes them fun to listen to, so what do we do ? If we do it right, if we really go and read Hoffman's iron law, we will realize that it is not as simple as it seems. For this to be true, the speaker box must have an airtight seal, which makes sense. The correct sound is air and if there is an air leak.

Your speaker could be making sounds that you don't really want, so what would it be like if our speaker had a hole? What if she? What would happen if our speaker was not airtight? Yeah, remember this guy from the beginning of the video. a hole right in the back Yamaha didn't make this a watertight speaker why would they do so well when a speaker cabinet is sealed? The cone has to fight all that air pressure inside the speaker cabinet if you cut a hole in the box now. The speaker cone can move much more freely, which means it can get much louder with much less energy.

Let me show you that you see a speaker with a hole is just a container with an opening like this glass bottle and, what happens when we enter air and out of this container it resonates and what happens if we do the same but with a larger bottle well the frequency drops and the same thing happens with a speaker with a hole, the larger the speaker cabinet the lower that resonant frequency. In the 50s we didn't know what to do with this resonant frequency, but now we know that we can adjust it very precisely. the shape of the speaker and the shape of the hole to get a nice low resonant frequency that really gives us a base drive with some costs, to really get this base drive we still need a reasonably large speaker cabinet to make sure the leaky frequencies be nice and low, that's why that genel x sub from before was so big, there are some tricks.

You can do around this like passive radiators that JBL uses in many of their Bluetooth speakers, but even that won't give you the same rich, full base that you'll get as a really large speaker cabinet, while the cabinet size is not. To get the whole story of why some speakers produce a lot of bass, Hoffman's law tells us that cabinet size is the biggest part of the story and for that reason, small Bluetooth speakers will only be able to produce a limited amount of bass. real, or at least that's what it was. The case is Brain X by Brain Audio and this is the most basic Bluetooth speaker I have ever heard.

Brain claims on the Internet that this speaker violates Hoffman's iron law, which I was skeptical of at first, but then I used it and even with a seal. The subwoofer inside is loud, has excellent battery life, and produces sick bass, so how do they do it right? They did this with a clever mechanism called the MAG negative magnetic spring. We all know how a normal spring works. It has this original resting place position and the more you stretch it away from that original position, the more force is created when you want to close it again. A negative spring actually has the opposite properties, it also has a rest position and the further you move it away from that rest position, the more force there is. it's making the spring want to explode further from the resting position and that force is actually the perfect force to counteract all that air pressure we mentioned earlier in the video.

Remember how that air pressure will always push back on the speaker cone. wanting to force it back into the speaker cabinet, well now we have a magnetic force that counteracts everything, now it's not that simple that the brain uses permanent magnets in its magnetic spring and permanent magnets are not very smart because they are literally stones to throw . a little bit of intelligence into the equation the brain also uses a series of electromagnets to keep everything aligned these electromagnets aren't actually moving air they're just keeping everything in the correct position for the actual speaker driver and that negative spring but even if it's a technological Marvel, what's it really like to have it?

I've been using this Brain X at home for a few weeks and I love it for listening to music and especially watching movies in wired mode. The base is totally cool and pretty. It's by far the smallest and most complete home theater setup you can have and the midrange is surprisingly distortion free if you're looking for a Bluetooth speaker or want to replace a cheap old sound bar you have lying around your house and the $599 price tag . The label fits your budget. I would definitely take a good look at Brain X now. Just because this speaker breaks Hoffman's law doesn't mean it's a magic speaker that will solve all your audio problems that you don't have like the crystalline Imaging. and high end that you would find in a studio monitor or even the dvla Phantom which is twice the price, it also has some latency that all Bluetooth speakers have so if you are using it in a home theater setup We're definitely going to want to use it in wired mode, but that's not what this video is about.

I got really excited about this because it's proof that now is an amazing time to be an audio archive and I'm not talking about the old one. $2,000 preamp type audio file for school. I'm talking about a new guy who deeply appreciates all the smart innovation that companies are bringing to the table right now. There are main audio studio monitors that can seal and open their cabinets. There are PMC. mastering Stacks that cost six figures and look like they're owned by the Terminator, there's those MacBook Pro speakers that use some of the craziest signal processing ever and totally deserves its own video, there's those II wireless studio monitors, I'm sure they're called II, I know you've talked to them, I don't really know, no, I'm not sure, Ellis, how do you pronounce it?

Is it I I I or is it AA? It's I II, there are those II wireless studio monitors that have 16 milliseconds of transmission latency 44116, how does it work? It's not compressed and when a company comes out with something so new and cool, a technology that they say can be reduced to a headset and even a concert-grade speaker, come on, you have to make a video. About this, it's so new 10 years ago that a speaker this size just couldn't do that much base, so I hope this video inspires you to read your speaker's manual and learn all about the cool things it does under the good I hope this video inspires all the cool speaker manufacturers to be more transparent about how their products actually work, looking at you Apple and I hope this video has worked to spread the word about some really cool technologies, but in the meantime, I'm Ellis. it's the studio, thanks for watching, like and subscribe and go see Dune 2, it's like it's the best movie of all time.
