Mini SubHarmonics hardware
Standalone hardware.
More bass than you've ever heard before
Sometimes you’re not hearing something simply because it isn’t there.
Most music, no matter how well produced, lacks the very bottom of the frequency spectrum.
Down there, between 5 and 40 hertz, lives the depth, the kind you feel more than hear.
The kind that gives your sound weight.
The Mini SubHarmonics is a small, handcrafted hardware unit that brings exactly that part back.
It’s a DSP-based bass enhancer, built for those who want to truly hear what their subwoofer is capable of.
No software, no plugins, no computer required.
Just connect it via RCA, adjust gain and mix, and you’ll instantly hear what you’ve been missing.
What does it do?
Subharmonics are frequencies that sit one octave below the original signal.
The Mini SubHarmonics detects low tones in your audio and adds carefully generated
layers underneath using smart DSP technology.
Nothing overblown, nothing fake.
This is real subwoofer enhancement for your setup.
What many people don’t know: there’s a surprising amount of music that simply doesn’t contain those deep lows.
Older productions from the eighties, nineties, and even modern tracks often lack true bottom-end.
Not because the music is bad , back then, the technology just wasn’t there. And today?
It’s often a stylistic choice.
Strangely enough, even now there are plenty of songs released without real sub-bass content.
There are exceptions. Boris Blank of Yello, for example, has long used subharmonics intentionally in his productions.
But that’s still rare. With the Mini SubHarmonics, you can bring that missing depth back in.
You don’t have to change the mix, you simply restore what’s not there.
Think of it as a bass upgrade for your system.
The result is a fuller, deeper sound.
Your tracks gain real foundation, films feel more intense, and your system finally reveals (and delivers) what it’s truly capable of.

What exactly does a subharmonic do?
Subharmonics allow frequencies to be reproduced lower than what is originally present in the signal.
This means they effectively create additional low tones that were not (or barely) there to begin with.
It generates frequencies that are exactly half of the original frequency, hence the name SubHarmonics , see pictures below
As a result, you get a deeper, fuller bass.
The signal is essentially split, creating extra layers in the low end.
In short: Subharmonics enhance the low end by adding artificially generated
deep tones for a richer sound experience.

Includes power supply for home and car use
Is my equipment compatible?
Mini SubHarmonics works with any audio system that has line-level (RCA) connections,like mixers,
DACs, audio interfaces, or preamps.
It does not connect directly to speaker outputs or headphone jacks.
Your amp and speakers must be able to handle sub-bass between 5 Hz and 40 Hz.
Most home cinema subs and full-range systems will work just fine — but check your gear's specs to be sure.

🎧 Recommended Headphones
These models perform well below 20 Hz and are great for demoing subharmonics:
Sony MDR-7506
Audio-Technica ATH-M50x
Beyerdynamic DT 770 Pro
Sennheiser HD 280 Pro
AKG K371
Use with a good source (DAC or interface) for best low-end results.
Power supply Mini SubHarmonics:
Runs on 9–14V DC, so it’s perfect for both home and car audio setups.
Adapter and 12V car cable are included.

Low frequency test video
This video plays 10 seconds per frequency, starting from 100 Hz all the way down to 20 Hz:
100 Hz → 50 Hz → 45 Hz → 40 Hz → 35 Hz → 30 Hz → 25 Hz → 20 Hz
Use a subwoofer or quality headphones for best results,
many systems won’t reproduce anything below 40 Hz without help.
Want to feel the missing lows? That’s where Mini SubHarmonics comes in.
The man behind the Mini SubHarmonics hardware
My name is Hans Scholtze.
I love technology and sound. And I love building things that truly add something.
Not mass products, but hardware I’d want to use myself.
The Mini SubHarmonics is one of those things.
The bass booster enhancer in process!
