Im a retired audio engineer and I have to say this is very impressive. Not only your true understanding of how it works but your fabrication as well. I want to build one of my own now! You've gained a new follower 👍

[@cornboxgod]

this is the madness that every engineer has on the inside embodied into one person. From showing his mom asking about her bathroom shaking, to the over-engineered brackets, to him filming the most random, unexpected, and extremely entertaining thing I have ever seen on youtube, the hat thing, while he was waiting for his dremel to cool down (and he placed it in the fricking fridge). This is what every engineer wants to be. not this multimillionare who revolutionized science, but the equivalent of daniel fajkis. godspeed my brother, and keep making more videos. you are now my new role model.

As an audio engineer I am highly impressed. The power you have with that. You could probably monetize it with sub frequency research

[@DarkAttack14]

There are already professionally produced rotary subs in use! The Thigpen TRW-17 produces 115+ decibels between 1-20 hz with a power input of 150 watts

[@markturner2561]

11hz is about the resonant frequency of the human eyeball if I recall, and in one case a malfunctioning fan actually created that frequency in an office building. It will distort vision and give people headaches and sometimes mild shape hallucinations. So you should try that.

[@Artem4egg_]

Nitro is very reactive and dangerous Make it Lmao

[@glashoppah]

Top fuel dragsters create sound pressures that distort the eye and cause the whole experience of watching them from up close to be especially bizarre and trippy, as the entire universe flexes and warps. It’d be great to troll your friends with a tiny remote to turn that shit on and have it start shaking their eyeballs in your house.

[@4ae109]

@@theoneway22Some of the people in the office building had their eyes ruptured or damaged. Just kidding.

[@FlyntofRWBY]

The only problem about this is that everybody’s eyes will have a different resonant frequency that changes throughout the day as the pressure of the liquid in our eyes changes as the day passes.

That's really the upper limit for these, a traditional subwoofer is more effective above 20 Hz.

[@MonsterJuiced]

I have a bass guitar with ultra, ultra thick strings designed especially for frequencies below 10hz. Unfortunately non of my amplifiers do it justice, I need something like you've made to get the gigantic sounds and air pumping through the room.

[@MoonberryJam93]

Bro literally answered a question I've had for my entire life: how would you generate loud, low frequency sounds without an absolutely massive speaker coil?

[@asyncasync]

While rotary subwoofers are effective at creating the sensation of very low-frequency sounds, they do so through a fundamentally different mechanism compared to the propagation of genuine low-frequency sound waves. The rotary subwoofer's method of operation involves local air pressure modulation, which does not result in the forward-moving wave characteristic of a true 1 Hz sound wave. But it probably feels pretty close to the real thing anyway...

[@fuzzypancake123]

This is super cool but it would be really interesting to hear how it sounds at like 50hz. To hear if it's actually making accurate sound

[@bosssavage3325]

Find the resonate frequency with your house so we can watch it fall apart.

Add aerofoils to the blades to increase their air moving effectiveness. The shape of the "wing" has a HUGE impact on how much air it moves.

But then it won't be symmetrical for moving air in versus out.

You've done some spectacular work here. As far as I know Bruce Thigpen of Eminent Technology makes the only commercially available infra-bass sub-woofer of this type. He only sells it through his trained professionals who must also install it because of the dangers involved (and we're not just talking about exposed fan blades). What you've done on the budget you state is amazing.
