Boosting low-end with a traditional EQ introduces unwanted sub-bass mud, robs your mix of headroom, and creates a flabby, uncontrolled low-end
SubMass fixes this by using a specialized, interactive filtering circuit. It creates a tight, resonant volume peak right at your chosen target frequency while simultaneously executing an aggressive high-pass cutoff immediately below it.
WHAT IT FIX: Weak low-end, Muddy mixes, Monitoring translation, Inconsistent sustain

SUBMASS by DSPTone
SubMass fixes this by using a specialized, interactive filtering circuit. It creates a tight, resonant volume peak right at your chosen target frequency while simultaneously executing an aggressive high-pass cutoff immediately below it.
Immediate psychoacoustic illusion of weight, punch, and authority
that translates perfectly to any speaker system, without adding unnecessary sub-bass clutter.
Unlike tools that use subharmonic synthesizers or artificial harmonic distortion, SubMass FX achieved its massive low-end purely through a precision-engineered, resonant solid-state filtering
Making your bass instruments feel larger, more focused, and mix-ready.
A simple low-shelf & EQ bell is static...
But SubMass is dynamic in perception, it reinforces what is already there.
Whether you struggle with a thin DI bass or an 808 that needs “chest feel,” SubMass delivers analog-style low-end control in a clean digital form
WHAT IT CAN DO
- Kick Drums (Acoustic & Electronic): Adds incredible chest-thumping punch to 808s, 909s, and rock kick drums.
- Bass Guitars & Synths: Locks down the fluctuating low-end of a bass performance, giving it a consistent, steady foundation.
- Voiceover & Male Vocals: Restores proximity effect to thin, poorly recorded microphones, giving vocals a deep, cinematic authority.
- Tom-Toms: Tightens floor toms, accentuating their deep resonance while filtering out muddy bleed from the rest of the drum kit
