[@MurderousMindstate]

@@nathanbulle5782 This is not practical for automotive use though in the house it will be better. Nobody wants to hear that fan running constantly nor to have the trunk open nor to be freezing cold. You need to explore the original rotary design with a shroud and alternating current fan like the old theater subs and phoenix gold rotary sub. This way the air itself is moving in and out. Yes it is impressive to see the doors moving like they are. With that being said I think you should look into using voice coils out of a computer hard drive to drive your fan blades tilting rather than a conventional sub magnet. Yes perhaps you will need to likely run one on each blade. This design has been done but the HDD coil design has not. This is your opportunity to be TRULY innovative. You are welcome to use the idea. I have faith that you can do it so when you become a millionaire I want 15% for the IP rights. :)

[@nathanbulle5782]

@@SaltyAsTheSea the weight of the air, the pressure from the air, and the moment of inerta of the individually tilting blades all play a role in how quickly the blades tilt. On this build, the blades start to drastically decrease in maximum tilt angle after passing above 25 hz (25 tilts per second). A model with thinner blades could do more drastic tilts per second (say 50 tilts of 45 degrees per second) since the moment of inerta of the blades gets drastically reduced. Also the sensation feels like your insides a pipe organ (actually pretty much exactly like rolling a back window down in your car when driving 80 mph). Does this answer your question?

The articulating hardware moving the vanes, and the vanes are predictably noisy. It wouldn't be too hard to make a silencer box on both sides. The high frequency noises can be filtered with the correct sound absorption materials, while allowing full air flow. There are currently at least two people working on rotary subs, the weak point is the hardware. The other guy is using model helicopter hardware that changes the blade angles much like a rotary sub. I think high quality components will be quieter because of tighter tolerances. You are doing an excellent job with this project, I am a speaker builder, I am impressed with your ability to translate a complex commercial product into a working hobbyist prototype. There is definitely a market for a consumer level product based on this concept. See if you can get the attention of a venture capitalist with vision, and you may be able to develop a viable product.

But don't skimp on protective gear you should wear gloves will resist the resin you're using and at least an n95 mask.

While I'll layout some criticism, overall cool demo. 1. Rotary sub requires an infinite rear enclosure, and technically an infinite front enclosure. In a house the volumes can approach "infinite" for any measurable usefulness. In a car, it cannot. you tested with the trunk open, is evidence enough. You'd have to test with the truck closed, and then it's not going to work very well. The blades will be forcing air into the car while the gap on the edge is going to hiss from the air trying to get back in the trunk. 2. The part where you turn on the rotary sub and on the mic you pick-up this loud ... Fan sound... And you comment over it explaining that with it on its inaudible and use a subsonic mic/meter as the indication of information. 3. The infinite baffle sub you have directly next to your rotary which would be working against your goals. Presumably you are not playing sound from it, which means that it's flexing negative as the pressure in the car builds and forwards when it drops.

If you can provide some form of contact maybe we could discuss and you could swing by

[@steveclark9934]

This is pretty cool I also like to see what those big $400.00 earthquake tactile transducers could do or even bigger commercial ones in a vehicle

[@nathanbulle5782]

The tactile transducers are so stupidly simple lol

[@garrettburrows442]

Dude clean the inside of your car, but I am impressed because I've never seen one in a car before

[@occupyallthethings]

Can I suggest another test with a bunch of balloons or ribbons/strings or a pom pom so we can see how the air is moving back and forth? Or maybe even a fog machine??

[@elliothickle3247]

I thought about doing a rotory sub but having mounted in the spare tire and having it vent out the bottom of the car, but all the intricate mechanical parts seems like it would need a lot of service/maintenance

[@nathanbulle5782]

It might get dirty possibly

[@terrancethomas5820]

So you technically sitting inside the enclosure 😂 thats sick

[@jaredombui3366]

You just did unexpected, big up

[@nathanbulle5782]

Yup

[@orocris]

It is so interesting, i think it can be suitable only in cases or places when you listen to music to a high volumes because the fan noise is so annoying.

[@nathanbulle5782]

Yeah the fan noise sucks. These things are more made for buildings to be honest. Right now I just use a 25hz tuned sub box in the car and it sounds fantastic

[@orocris]

@@nathanbulle5782 That tuning is a good option, also, the most of the songs does not get down below 30 Hz.

[@nathanbulle5782]

@@orocris yeah the box can even play 20 hz

[@QUAKEPOWERZ]

🤔...✨✨✨ ❤️💯 Very nice do more experimenting 💯

[@tuned6222]

This was something i wanted to do aswell about 3 months ago, but i never got around to actually building a rotary subwoofer.

[@nathanbulle5782]

It's a little difficult but not like THAT hard

[@tuned6222]

@@nathanbulle5782 Yea

Long time ago, my dad shook shelves with normal subwoofers, imagine this one!

[@nathanbulle5782]

Yeah this might break the shelves lol

[@gravedigga6979ify]

Pretty insane man.....very cool

[@ZR2DAILY]

I can't Take this guy seriously, with a Rockville sub

[@nathanbulle5782]

LMAO!

[@cheze_bun]

Sounds like my old dads car on while everyone was screaming lol 8:44

[@danielsigursson6215]

Made me feel stupid for a sec thinking "when is the abss gonne hit" watching this on a laptop. Would be cool to hear in person.

[@nathanbulle5782]

I wish someone could come hear it

[@LexusYachtClub]

You made a comment about the rotary sub being at full volume, but if you could put up with more fan noise, all youd need to do to move even more air around is increase the fan speed

[@nathanbulle5782]

Increasing the fan speed helps with higher frequencies but is also harder on the coil.

[@Hammerback0]

Someone walking by will be calling for the exorcism of that car😂

[@nathanbulle5782]

Lol

[@raccoonvallie]

Keep up the work i definitely digging it ive been wanting to make one for some time now and this definitely is enspiring
