How to Mix Sub Bass for Tech House (Without It Disappearing on Club Systems)
We've all sat in a club listening to our own demo through the system thinking "where did the bass go." The kick is there. The hats are there. The bass is technically there, but it's not landing. It's not moving the room the way the other tracks in the set are moving the room.
This is the most common technical problem we see in tech house demos. Producers spend hours tuning their bass on headphones or near-fields. The bass sounds great in the studio. Then it gets played on a real system and disappears.
The reason isn't usually about the sound design of the bass. The reason is almost always about how the bass is mixed: what's happening between 30 Hz and 200 Hz, the mono compatibility, the sidechain relationship to the kick, and the level.
Here's the order we work through when we're mixing sub bass for tech house, and why each step matters when the track moves from studio to floor.
The fundamental problem
Most studio environments (headphones, near-field monitors, even some midfield monitors) don't accurately reproduce frequencies below 60 Hz. Even excellent monitors like Genelec 8030s or Adam A7Vs roll off significantly below 50 Hz. Most consumer headphones (yes, including premium models) over-emphasize 80 to 150 Hz to compensate for what they can't deliver below.
This means: what you hear as "the bass" in your studio is probably the harmonics above 80 Hz, not the actual fundamental of the bass note.
A club soundsystem is the opposite. A proper club system (Funktion-One, Void, L-Acoustics) reproduces 30 Hz to 100 Hz with massive headroom. The fundamental of your bass note is suddenly very loud and very present. If you haven't mixed for that, the relationship between fundamental and harmonics is going to be wrong.
This is why bass that "sounds great in the studio" disappears in the club. It was always being misrepresented in the studio. The club is showing you the truth.
Step 1: Tune the bass to the kick
The single most important step. In tech house, the kick and the bass should share the same fundamental frequency, or the bass should be a perfect octave above or below the kick's fundamental.
If your kick is tuned to A1 (55 Hz), your bass should sit on A or its octaves: A0, A1, A2, A3. The bass can move melodically (D, E, G, etc.) but the most important note in the pattern (usually the one that lands on the kick) should reinforce the kick's fundamental.
Why this matters: when the kick and bass share fundamentals, they reinforce each other constructively. The low end sounds "locked." When they don't share fundamentals, they fight, and the result is a muddy, weak low end that the club system will brutally expose.
How to do it: - Drop your kick into a tuner (Ableton's built-in tuner works fine, or use Mixed In Key for the whole project). - Note the pitch. Tech house kicks are usually A, A#, B, or C. - Build your bassline in that key (the song key). Most tech house is in A minor, A# minor, or G minor. - Make sure the root note of your bassline lands on the kick hits.
Step 2: High-pass the bass at 30 Hz
There's nothing useful below 30 Hz for tech house. Even a great club system will struggle to reproduce content below 30 Hz cleanly. All it does is steal headroom from the frequencies that matter.
Drop a high-pass filter on your bass channel. 30 Hz, 24 dB/octave slope. Don't go higher than 30 Hz (some producers high-pass at 40 or 50 and lose the weight). Don't skip this (some producers leave it unfiltered and the track can't get loud).
Step 3: Sidechain to the kick (but not aggressively)
Tech house bass needs to duck under the kick. But aggressive sidechain (the obvious "pumping" sound) is wrong for the genre. You want the sidechain to be felt, not heard.
Settings we use as a starting point: - Compressor sidechained to the kick (use Ableton's Compressor or any standard sidechain plugin) - Threshold: set so that you're getting 4 to 6 dB of gain reduction on each kick hit - Attack: 1 to 3 ms (fast enough to catch the kick transient) - Release: 80 to 120 ms (slow enough that the bass doesn't bounce back too obviously) - Ratio: 4:1 to 6:1
The goal: the bass dips clearly under each kick hit, then recovers smoothly before the next one. You should see the gain reduction meter dipping in time with the kick. You should not hear an obvious "wub wub" pumping sound.
Step 4: Saturate the harmonics (not the fundamental)
Pure sub frequencies translate poorly through most playback systems, even good ones. Phones, laptops, car stereos, and even some smaller club systems don't have the speakers to reproduce a 50 Hz fundamental.
The solution is harmonic saturation. By adding harmonic content at 2x, 3x, and 4x the fundamental, you create perceived bass on systems that can't reproduce the actual fundamental.
How to do it: - Drop a saturator after your bass synth (Saturator, Decapitator, RC-20, FabFilter Saturn, whatever you have) - Use a gentle saturation curve (soft clip, not hard clip) - Drive it until you can clearly hear harmonic content being added (5 to 15% drive, depending on the plugin) - A/B against the unsaturated version: the saturated version should sound noticeably "bigger" without sounding distorted
What this does: it gives you bass content from 100 Hz to 800 Hz that consumer playback systems can reproduce, so the bass is felt even when the actual sub is being missed. On a club system, the original fundamental is still there, plus the added harmonics give it more presence.
Step 5: Force the sub to mono
If your bass is stereo, the sub portion will partially cancel itself out when summed to mono. Club systems summed to mono is rare but not impossible (especially in smaller venues), and even in fully stereo clubs, the sub bins are usually summed to mono because directional sub-bass below 100 Hz is physically very difficult to achieve.
Drop a utility/utility plugin on your bass channel. Force everything below 120 Hz to mono. In Ableton, this is the Utility plugin's "Bass Mono" control set to 120 Hz. In other DAWs, use any equivalent (FabFilter Pro-Q 3 has a mono band feature, Ozone has a stereo imager with mono-below).
This guarantees that the sub portion of your bass is mono-compatible. The stereo content above 120 Hz can stay stereo for width.
Step 6: Check the level relative to the kick
The bass should peak roughly 3 to 6 dB below the kick on a peak meter, but be roughly equal to the kick on a loudness meter (LUFS short-term).
What this means in practice: the kick should be the loudest transient, but the bass should sustain longer and feel just as present in the mix.
Common mistake: producers mix the bass too quiet because it sounds "too loud" on near-fields. On a club system, that quiet bass disappears. Trust the meters, not your ears in a non-ideal studio environment.
Reference: pull up a Solardo, Patrick Topping, or Chris Stussy track in your DAW. Use a metering plugin (Youlean, FabFilter Pro-L 2, Insight) to compare the kick and bass levels. You'll see they're much closer in level than most home-studio mixes have them.
Step 7: Check on multiple systems before bouncing
Before you commit to a mix, listen to it: - On headphones (Sony 7506, AirPods, anything) - On laptop speakers - On a car stereo if you can - Through a Bluetooth speaker
The bass should be audible on all of them. If it disappears on any of these, the problem is your harmonic content (the higher frequencies that consumer systems can reproduce). Go back to step 4 and add more saturation.
If the bass is clearly audible on all of them but the mix is muddy, the problem is your fundamental level (the lower frequencies that crowd the kick). Reduce the bass level by 1 to 2 dB and try again.
The full chain we typically run
Here's our actual tech house bass channel strip, in order:
- Sub bass synth (sine wave from Operator or Serum sine table) at +0 dB
- EQ: high-pass at 30 Hz, 24 dB/oct slope. Small notch at 200 Hz (-2 dB) to leave room for kick body
- Sidechain compressor: ducked to kick, 4-6 dB GR, 2 ms attack, 100 ms release
- Saturator: soft clip, 10% drive
- Utility: mono below 120 Hz
- Level: matched to kick within 3 dB on peak meter
If we're using a sample bass (one-shot or loop) instead of a synth sub, we sometimes layer a second sub-only sine wave underneath for low-end weight, with its own sidechain compressor.
One thing producers underestimate
The biggest mistake we see is producers trying to fix a bad bass mix in mastering. Mastering can't fix a bass that's poorly sub-related to the kick. It can only make it louder. If the relationship between kick and bass is wrong, mastering will make the wrong relationship louder.
The bass mix has to be right in the mixdown, before it goes to a mastering chain. Spend the time at the mix stage. Don't expect Pro-L 2 or Ozone to save you.
FAQ
Q: What frequency is "sub bass" in tech house? A: Sub bass usually refers to anything below 80 Hz. The fundamental of most tech house basslines sits between 40 Hz and 80 Hz (A1 at 55 Hz is the most common).
Q: Should tech house bass be mono or stereo? A: The sub portion (below 120 Hz) should be mono. Content above 120 Hz can be stereo for width. Use a utility plugin to force the sub to mono while keeping the higher harmonics stereo.
Q: Why does my bass sound great in the studio but disappear in the club? A: Almost always one of three reasons: the bass isn't tuned to the kick (they're cancelling each other), the bass is too quiet relative to the kick, or the bass has stereo content below 120 Hz that's partially cancelling when summed to mono.
Q: Do I need to high-pass my tech house bass? A: Yes, at 30 Hz with a 24 dB/octave slope. There's no useful content below 30 Hz for tech house and it steals headroom from frequencies that matter.
Q: Should I sidechain the bass to the kick? A: Yes, but subtly. You want 4 to 6 dB of gain reduction on each kick hit with a fast attack (1 to 3 ms) and medium release (80 to 120 ms). The pumping shouldn't be obvious, just felt.

If you're working on tech house and your bass mixes aren't translating to club systems, the techniques above will get you most of the way there. The other half is starting with sample content that's already tuned and ready to sit in a mix. Pressure (/products/pressure) has tuned kicks at A1, A#1, B1 and C2 with the click EQ'd and the sub already cleaned up, which removes about three steps of the workflow we walked through above. Not a magic fix, but it gives you a starting point that's already pointed in the right direction. Either way, the time you spend learning how to mix the low end properly is the most leveraged time a tech house producer can spend.
