Feel the bass that was always missing
Most music lacks content below 50 Hz. Not because it's bad, but because it was never recorded there. The Mini SubHarmonics generates those frequencies in real time. No software. No plugins. Just connect and feel it.
See what your speakers are missing
Watch the Mini SubHarmonics in a real audio setup. The LED indicators react in real time as sub-bass is generated. Bass you can see, and more importantly, feel.
🎧 Best experienced with a subwoofer or quality headphones.
How Deep Is Your Bass?
Press play. Then switch.
Both tracks are the same recording. One original, one with SubHarmonics processing. Switch while playing to hear the difference at the exact same moment in the track.
💡 Most noticeable on kick drums, bass lines, and low synths.
The missing octave, recovered
For every low frequency in your music, the Mini SubHarmonics generates a tone exactly one octave lower. Mathematically precise and fully controllable.
Also known as a Subharmonic Processor — hardware that generates new sub-bass frequencies, not a bass booster.
Signal Detection
The DSP analyzes your incoming audio in real time, identifying frequency content in the low-end range.
Subharmonic Generation
For each detected frequency, a tone exactly one octave lower is generated. Mathematically precise and phase-aligned.
Controlled Blending
Gain and mix knobs let you dial in exactly how much sub-bass to add. Subtle enhancement or full rumble.
The spectrum doesn't lie
Left: with SubHarmonics processing. Right: without. The difference below 60 Hz is clearly visible and even more clearly audible.
Built for serious listeners
Home Cinema
Film soundtracks with the physical weight they were designed to have.
Car Audio & SPL
Runs on 9–14V DC. Real sub-bass on the road without changing your amps.
Studio & DJ
Hear how your tracks behave at sub-20 Hz frequencies during playback and mixing.
Synths & Sound Design
Add physical weight to 808s and bass synths. Electronic music comes alive.
Hardware with a single purpose: Pure Sub-Bass.
Connect via RCA, adjust the mix knob, and you'll immediately hear what your system was missing. No setup, no software, no nonsense.
Our shielded aluminum enclosure and internal power filtering deliver a –83 dB noise floor — even on a standard wall adapter.

The spectrum comparison
Left: with SubHarmonics. Right: without. The sub-bass region below 60 Hz shows a clear, measurable difference. Not a subtle tweak.
Works with your setup
Any system with line-level (RCA) outputs. If your system has RCA connections, the Mini SubHarmonics plugs straight in.

Can your system go this low?
This video steps from 100 Hz down to 20 Hz, 10 seconds per frequency. Most systems drop out before 40 Hz.
100 Hz → 50 → 45 → 40 → 35 → 30 → 25 → 20 Hz
🎧 Subwoofer or headphones required.
Hans Scholtze
I've been fascinated by low frequencies for a long time. Not just the bass you hear, but the bass you feel. The physical weight of a film scene. The sub-20 Hz content in a synthesizer that your body registers before your ears do.
What I discovered is that most audio systems, even the good ones, never receive those frequencies. The source material doesn't contain them. Older recordings lacked the technology. Modern productions often omit them by choice.
The Mini SubHarmonics was my answer. Hardware with no latency, no driver installs, no software updates. A precise device that slots into any line-level signal path and adds the missing octave back in.
Everything is handbuilt in the Netherlands, in small batches. I test each unit before it ships. It only ships when it's right.
Designed to do one thing, and do it perfectly.
No software required
Zero dependencies. No drivers, no app, no cloud. Works the moment you plug it in.
Handbuilt, not mass produced
Small batches from the Netherlands.
No compromises
Low noise floor. Minimal latency. Aluminum enclosure. Built the way I'd want to receive it.
