Question 1

How do I get deeper bass out of my subwoofer?

Accepted Answer

Most people think a bigger or more expensive sub will solve the problem, but in 90% of cases it's not the subwoofer itself. It's simply not in the recording. The Mini SubHarmonics calculates in real time what should have been in the sub-bass region (10 to 40 Hz) and sends it to your subwoofer.

Question 2

My sub doesn't go deep enough, what now?

Accepted Answer

Test it yourself first with a sweep from 100 Hz down to 20 Hz. Can you still hear it at 30 Hz and does it drop out? Then it's the sub itself. Does it go deep enough yet you still miss the punch? Then it's the source. That's exactly what the Mini SubHarmonics is built for.

Question 3

How do I get more bass out of my music?

Accepted Answer

It depends on where the problem sits. Play a sweep from 100 Hz down to 20 Hz. Does it drop out somewhere below 30 Hz? Then it's your subwoofer or speakers. But in 90% of cases the problem isn't your system, it's the music itself: most recordings simply don't contain frequencies below 50 Hz. A bass booster or EQ won't help, there's nothing there to boost. The Mini SubHarmonics generates that missing sub-bass in real time.

Question 4

Does the Mini SubHarmonics do bass boost?

Accepted Answer

Yes, but differently than you're used to. A regular bass boost (on your amplifier, in an EQ, or via a bass booster app) makes the existing bass in your music louder. More volume, often also more mud and distortion. If there's nothing below 40 Hz in the recording, there's still nothing below 40 Hz after boosting. The Mini SubHarmonics works fundamentally differently: it generates new sub-bass tones (10 to 40 Hz) that were never there, and mixes them in a controlled way. Hear 80 Hz? It adds 40 Hz. Hear 60 Hz? It adds 30 Hz. The effect people search bass boost for, more and deeper bass you hear and feel, you absolutely get. But clean, without distortion, and working even on music where regular boost has no effect.

Question 5

What is sub-bass exactly?

Accepted Answer

Sub-bass is everything below 60 Hz. The part of the sound you feel more than you hear: an organ pedal, a film explosion, an 808-drop in electronic music. Sub-bass has roughly two regions: 40 to 60 Hz (the punch, clearly audible) and 10 to 40 Hz (the rumble, mostly felt). Most recordings miss the deepest portion, not because the music is bad, but because those frequencies were never captured in the recording.

Question 6

Is my subwoofer compatible with the Mini SubHarmonics?

Accepted Answer

Almost any active or powered subwoofer with a line-level RCA input works. The Mini connects between your pre-out (from your amplifier or AV receiver) and your subwoofer input. What your sub needs to be able to do is go low enough to reproduce the generated frequencies. Test first with a sweep from 100 Hz down to 20 Hz: can you still hear or feel something at 30 Hz? Then your sub is compatible.

Question 7

What's the difference between a bass booster and a subharmonic processor?

Accepted Answer

A bass booster makes existing bass louder. If there's nothing below 40 Hz in your music, there's still nothing after boosting. A subharmonic processor like the Mini creates new tones, one octave below what's already there. Real depth instead of amplified mud.

Question 8

Can I improve my subwoofer without buying a new one?

Accepted Answer

Yes, often you can. A good sub can technically reproduce sub-bass just fine, it's just not in the source. For €199 you add the missing frequencies, instead of spending hundreds of euros on a new sub.

Question 9

Can I connect the Mini SubHarmonics only to my sub without affecting my main signal?

Accepted Answer

Yes, that's actually elegant. With a preamp with two pre-outs, send one to your regular amplifier and route the other through the Mini SubHarmonics to your active subwoofer. Your main signal stays clean.

Question 10

Does the Mini SubHarmonics work with old recordings and LPs?

Accepted Answer

Yes, especially with older recordings the difference is most noticeable. Tape recorders from the 70s and 80s lost everything below 50 Hz. With turntables use an EQ filter below 40 Hz to remove stylus rumble.

Question 11

How is it different from the old dbx subharmonic processors from the 80s?

Accepted Answer

Dbx pioneered this technology, but their analog circuits added coloration and noise. The Mini SubHarmonics uses modern DSP technology for a cleaner signal path and lower noise floor (-83 dB).

Question 12

What instruments play below 50 Hz?

Accepted Answer

In an orchestra: timpani, organ pedals, five-string double bass. In modern music: 808s, synth bass, sub-drops. And in films: the LFE channel for explosions and rumble.

Question 13

Does this work for home cinema and films?

Accepted Answer

Yes. Connect between AV receiver line-level pre-out and subwoofer. Films with LFE content benefit most, especially older films.

Question 14

What is a DSP Subharmonic Synthesizer?

Accepted Answer

Hardware that uses digital signal processing to create new sub-bass tones based on what's in your music. For each detected low frequency, a tone exactly one octave lower is generated, phase-aligned.

Question 15

What independent reviews are there?

Accepted Answer

Hans Beekhuyzen (105,000+ subscribers on YouTube) tested the Mini in his reference setup. There are also several buyer reviews via Marktplaats and Ebay. To date, not a single unit has been returned.

Question 16

What's in the box?

Accepted Answer

The Mini SubHarmonics itself (aluminium 70x60x30 mm), EU power adapter, 12V car cable, and a quick start guide. Connect via stereo RCA and you're ready.

Question 17

Is there a software version or plugin for Roon or foobar?

Accepted Answer

Software versions exist, but we deliberately chose hardware: no latency, no drivers, works everywhere with line-level RCA outputs. No subscription or OS updates that break things.

Question 18

How do I get deeper bass in my hi-fi setup without buying a new subwoofer?

Accepted Answer

In most hi-fi setups the problem isn't the sub, but the music itself. The Mini SubHarmonics calculates the missing sub-bass in real time and sends it to your existing sub. For €199 you get deeper bass from the same system.

Question 19

Can you actually hear deep bass, or do you only feel it?

Accepted Answer

Both. The deep bass you actually hear sits between 25 and 40 Hz. Below that, you feel it more than you hear it. The physical side of bass that most music is missing.
