What is Subzix Raw?
Real sub weight shouldn't take a mixing degree. Subzix Raw is the free, one-knob path to bigger, deeper low end on basslines, kicks, synths, and full mixes: turn up SUB and it gets heavier, never louder. No menus, no setup, just the drop your track's been missing.
Subzix Raw makes your low end bigger from a single knob. It tracks the pitch of your bass and adds phase-locked octave-down sub harmonics, low-end saturation for richness, and a touch of stereo width on the top: the same engine from the full Subzix, here pinned to Warm saturation and 100% wet. A built-in gain bias means the result is always heavier and level-matched, so you hear weight, not just volume.
Quick start
Get a result with Subzix Raw in under a minute.
- Insert it. Put Subzix Raw on the track or bus you want to change.
- Turn SUB up. Raise SUB until it sounds right.
- Compare. Bypass the plugin in your DAW to hear the difference.

The knob
- 2SUB: a single macro that drives every hidden parameter at once. As you turn it up, octave-down sub harmonics come in first, bass saturation thickens the low end, and the stereo top opens up slightly. Bass and output gain are biased down as you push, so a fuller low end never turns into a volume jump. At zero, Subzix Raw is transparent.
Key specs*
| Linkwitz-Riley crossover | The signal is split into a bass band and a top band around a fixed crossover point before any processing. |
|---|---|
| Pitch-tracked, phase-aligned sub | The engine tracks the pitch of your bass and generates a sub one octave below it (with a 27.5 Hz fallback), gated so it never fires on near-silent input and capped so the generated sub never exceeds the original bass energy; the bass band is phase-aligned and summed to mono with +3 dB compensation to stay tight and centered. |
| Warm saturation with safety filtering | A 25 Hz safety high-pass removes headroom-eating subsonics, the Warm bass saturation runs at 2× oversampling to control aliasing, and a 5 Hz DC blocker follows. |
| Constant latency | The reported latency (crossover lookahead plus 2× saturation oversampling) is fixed and never changes as you turn the knob, so host delay compensation stays stable. |
| Output safety and denormal protection | A smooth-knee soft clipper provides a 0 dBFS ceiling followed by a NaN/Inf safety sweep, and denormal protection runs in every processing block with input sanitized before it reaches any filter. |
| Controls | One knob, SUB |
| Formats | macOS: AU, VST3, CLAP, AAX, Standalone. Windows: VST3, CLAP, Standalone |

How do I use Subzix Raw on a track?
- Insert it. Put Subzix Raw on the track or bus you want to change.
- Start with SUB at 0. At zero, Subzix Raw is transparent.
- Turn SUB up. Raise SUB until it sounds right. As you turn it up, octave-down sub harmonics come in first, bass saturation thickens the low end, and the stereo top opens up slightly. Bass and output gain are biased down as you push, so a fuller low end never turns into a volume jump.
What about the full Subzix?
Love the weight? The full Subzix goes deeper. The Pro version opens up the full sub-bass engine with a Linkwitz-Riley crossover, three bass saturation modes (Warm/Punch/Grind), envelope shaping, a sidechain pulse ducker, the Ice Chamber visualizer, and factory presets. Every control is explained in the Subzix manual.

Frequently Asked Questions
Is Subzix Raw free?
Yes. Subzix Raw is completely free: freeware, no trial, no nag screens, no expiration.
What does the SUB knob do?
SUB is a macro that drives Subzix's sub-bass engine, adding octave-down sub harmonics, low-end saturation, and a touch of stereo width together. Output is bias-compensated so your low end gets heavier, never just louder.
How is Subzix Raw different from Subzix (Pro)?
Subzix Raw gives you the Subzix sub-bass engine: pitch-tracked, phase-aligned octave-down sub: behind a single SUB knob with automatic level-matching. The full Subzix adds a Linkwitz-Riley crossover, three saturation modes, envelope shaping, sidechain pulse ducking, and factory presets.
Does Subzix Raw run on Apple Silicon and Windows?
Yes. Subzix Raw is a Universal Binary that runs natively on Apple Silicon (M1/M2/M3/M4) and Intel Macs, and ships as a 64-bit build for Windows 10 and 11.
Will Subzix Raw change my levels?
No. As you turn SUB up, the bass and output gain are biased down so a fuller low end stays level-matched and never turns into a volume jump. At zero the mix is fully transparent, so you hear more weight, not more volume.
Does Subzix Raw add latency?
Subzix Raw reports a small, constant latency (crossover lookahead plus 2× saturation oversampling) that never changes as you turn the knob, so your host's delay compensation stays stable.
