Canvas Audio – SubTec v1.0.3 for WiN

Based on the legendary vintage passive tube EQ with its “low-cut trick,” it simultaneously boosts and cuts the same frequency, allowing you to add warmth, punch, and clarity to bass, kick drum, or your entire mixing bus. One knob—and you’ve got perfect low frequencies.

A time-tested approach for low end excitement

Subtec is a low-end equalizer designed around the classic boost-and-attenuate trick. It adds punch, focus, and weight to your bass frequencies without the mud.

Low-end Sculptor

Built around the legendary vintage passive tube EQ’s “Low End Trick,” it boosts and attenuates the same frequency at once, letting you add warmth, punch, and clarity to bass, kick, or your entire mix bus. One knob and you’re locked into the perfect low end.

Boost and attenuate in one move

Balancing low end can be tricky. But the SubTec’s perfectly dialed in nature of the Boost/Atten knob keeps this genuine effect simple and lets you focus on using your ear to find the sweet spots. And with an extended and variable frequency range, you can dive into frequencies in between the original passive EQ units. And sometimes that magic happens in the in-between.

Saturate the subs

With multiple distortion options, SubTec makes anchoring your low end both fun and creative. In a single move, you can transform a weak, uneven bottom end into something focused, powerful, and harmonically rich, locking in one of the toughest frequency ranges with ease.

All you need, right in the canvas
