Hello Ive been learning allot about healing frequencies. 432hz. 528hz etc
But Im really confused by all the youtube videos with "earth frequency" 8Hz
No speakers can play this low. Whats up with all the videos?
How do I make a speaker play this?
Thanks

Yes, buy the rotary subwoofer. Its expensive, but it can produce sounds down to 1 Hz.

Yes, you can built it too, there are plenty youtube videos. You need to vibrate the blades. Whatever the frequency.
It's a translation error or misnomer/euphemism and refers to the 'brown note' said to be 5-10 Hz but depends...
I mean... I'm inclined to say it's crystals and magnets and astrology and woo-woo nonsense, so the fact that no speakers can play the 8 Hz has no impact on the experience. But maybe I'm wrong, what do I know?
If you want a sub to make 8 Hz, use a bass shaker. More targeted and cheaper than trying to make it air born with traditional speakers. Less likely to cause structural damage to your domicile as well. Tho do be aware that many DACs, Amps, digital codecs, etc would regard 8 Hz as out of band, and may have some high pass filter that would remove it.

Sure they can, just build a BLH with a driver that its Fs*Qts/2 = 16 Hz such as a reasonably cheap 32 Hz Fs, 0.5 Qts' subwoofer. Of course it will be huge unless a lot of drivers are used to shorten it just to make it loud enough to feel, but recommend leaving it outdoors because even my stereo pair of dual 15" 14 Hz subs has proven strong enough to damage my 'floating' floor house and good luck if you have neighbors closer than a few hundred feet.
Use a signal generator.
You're welcome!
Grab a 8x4' sheet of 20g steel suspend it with a spring in each corner, find a electric motor and gearbox combo that has a 480rpm output, set up a pulley and conrod like a car crankshaft and connect it to the center of the sheet... Confucius say's, Ye shall find the brown note one seeks. 
just take a closed box bass to a corner and lack in efficiency is compensated by the amplifier reproducing 8hz tone.
But be sure:
the myths are myths - not more than that.

@stevef22 As you have seen, 8Hz is below the passband of any normal transducer. This means that using the transducer to directly produce that frequency is not practical. The best option would be to design and build a large resonant system. I assume that you are not concerned with quick attack and decay, but rather to keep the tone going for a while. A resonance system will multiply the energy put into it, and this makes a single note LF resonator practical even when you cannot drive it with all that much SPL. The resonator will generate most of the output. VLF requires large volume displacements. This means that the cross sectional area of the resonator exit must be large, and the driver must have high Xmax and Sd. There are some drivers meant for open baffle use that have low Fs, high Xmax, and high-er Qts that might work well. Keep in mind that all of this will have to be very large to develop much SPL...
The above is assuming you want to pressurize a large space like a room with 8Hz. There is another way to get high SPL at very low frequencies: use cabin gain. Essentially you would build a closed box, essentially an oversized coffin, that is large enough for one person to remain inside. The drivers are arranged in the walls and can be unbaffled outside. The person gets inside and the lid is sealed. The coffin must be VERY solid and stiff. Relatively high pressure can be developed in the small space inside, and this produces much higher SPL compared to in a room or other open space. Take some care when testing this for the first time! You will still need several high Xmax drivers.

@geoffkait's second suggestion is often called "binaural beats"
https://pmc.ncbi.nlm.nih.gov/articles/PMC10198548/
"Binaural beats are an auditory phenomenon that occurs when two tones of different frequencies, which are presented separately to each ear, elicit the sensation of a third tone oscillating at the difference frequency of the two tones. Binaural beats can be perceived in the frequency range of about 1–30 Hz, a range that coincides with the main human EEG frequency bands. The brainwave entrainment hypothesis, which assumes that external stimulation at a certain frequency leads to the brain’s electrocortical activity oscillating at the same frequency"
. . .
"Specific effects of binaural beat stimulation on EEG parameters have been a research topic for almost the last two decades and have been investigated by a number of independent research groups. The included studies involved small samples of young adults, and applied binaural beat stimulation in the main human EEG frequency bands. The studies varied considerably with respect to their designs, procedures, measurement approaches, EEG parameters and analyses.
The synthesis revealed contradictory results, with five studies reporting results in line with the brainwave entrainment hypothesis [15]. Eight studies reported no effects in terms of entrainment, and one study reported mixed results. Entrainment effects in response to binaural beat stimulation compared to control conditions was found for the theta, alpha, and gamma bands, while none of the studies using stimulation in the beta frequency range found entrainment effects."

I was going to suggest something on the lines that Harry 72 has already done; the only other way I'd try would be a fan and organ pipe, but you'd need a LONG pipe, and if you don't make the of large enough diameter, you get over tones. Perhaps make an air tight cupboard, covered in cheep subs, and climb inside.
If you play 432 and 8 hz together it will cure neuropathy and menstrual cramps. I learned that in a sacred geometry Facebook group 😝
For the record I have incorporated two count em two Schumann frequency isochronic tones into my listening routine, it took a while to find ones that work best, some should work but don’t. Schumann tones from YouTube are streamed onto my iPad and smartphone. One on either side, you know, one for each brain hemisphere. Once the genie gets out of the bottle it can be rather difficult to put him back in. What does Schumann bring to the table? Dimensionality and realism. No, I’m not hot dogging you.

Yes, but only for listening to Schumann on headphones. The brain hears the difference frequency.
Am I now in phase with Mother Earth and resonating with the universe (or maybe just the solar system)?
The real Schumann frequency is produced by lightning storms around the world, ithe Schumann frequency exists in the trough between earth surface and upper atmosphere. Since the real Schumann wave is electromagnetic its wavelength is 24,000 miles.
The Schumann resonance is electromagnetic, not acoustic. The two cannot be conflated; what do you expect to achieve by making infrasound at this frequency, and what spl do you require?
