Bass XXL


Supersize Your Low End

Bass XXL offers a more effective way to get the thick and consistent low end that defines modern mixes. Thanks to a proprietary algorithm that creates harmonics above the root frequency, your bass will be enhanced even through earbuds and small speakers.

Plugin formats: VST, VST3, AU, AAX.


What People Are Saying

"When it comes to crafting the perfect low end for my mix, I used to rely on a specific set of tools. Bass XXL has replaced all the other enhancements I used to use for my low end. It has truly transformed the way I shape and refine my bass sounds.”

Matt Sim
Illenium, The Chainsmokers, Dillion Francis, Jackson Wang, Aya Nakamura

"Honestly Bass XXL is amazing. I get in 1 plug-in something I've been doing in every mix for years with 3 plug-ins. This will go into 100% of my mixes from now on."

Rob Kleiner
Grammy nominated producer / mixer for Sia, Labrinth, David Guetta

"For me, as I travel a lot, mixing the bass properly is the biggest struggle and issue that I face daily not being in my studio. I just dropped Bass XXL on a house bass and it sounds incredible so far."

Artist / Producer / DJ

"Bass XXL does that ever-so-useful trick of increasing the perceived loudness of sub bass on small speakers or devices and it does it very well. As a psychoacoustic enhancer it outshines the competition."

Wolfgang Gartner

Introducing Bass XXL

Create 'Brainwashing' Bass

No items found.

Bass XXL makes use of a proprietary algorithm designed to supersize the low end. The plugin accomplishes this by generating additional harmonics that are actually above the bass frequency you want to enhance.

This concept takes advantage of a psychoacoustic phenomenon that causes our brains to interpret sub bass audio largely based on its harmonics more so than the lowest sounds being produced. Even in the absence of sub bass frequencies, we fill in the blanks and perceive the bass as long as the proper harmonics are present.

With so many of today’s earbuds and small speakers unable to generate satisfying low end, Bass XXL comes to the rescue by enhancing your bass with fat and beefy harmonics that can be felt and heard.

Optimize and enhance your music’s bass with exceptional low end preservation and depth, thanks to algorithmic improvements that completely eliminate the phasing issues that plague competing plugins.

The ultimate low-end enhancement tool

Based on the cult success of our Bass XL V1, we wanted to raise the bar with Bass XXL and create the 'be-all-end-all' bass enhancement tool. Use the plugin to beef up bass lines, kick drums, toms, drum groups, or even entire mixes.

Silky harmonics made for bass

Bass XXL’s harmonics algorithm is custom developed for low-end duties. Unlike a sub-synth, it generates its harmonics entirely from your dry track, resulting in a natural and organic bass enhancement that blends perfectly. The algorithm combines the smoothness of analog saturation with digital precision and oversampling. Furthermore, we've eliminated the phasing issues that sometimes occur with this type of effect.

Relieving the pain

One of the biggest pain points in professional mixing is to get a defined low end that translates well to all listening devices. Bass XXL doesn't offer any miracle cure but it relieves a big part of the headache and makes your job a whole lot easier.

Dialing in the focus

Boost With Surgical Precision

No items found.

Low-end harmonics are a powerful thing. So before you add them, you'll want to determine exactly where to focus. Bass XXL offers flexibility with three distinct modes:


Manually select your desired frequency to add punch and heft to kick drums, percussion, one shots, and mix groups.

Root Note

For melodic instruments like synth or bass guitar, choose a root note to ensure that Bass XXL’s harmonic enhancements are in key with your track.


If you want Bass XXL to update its focus in accordance with tonal movements in your track, you can control the plugin via midi (for instance by linking it to your bass line).

Adding The Harmonics

Let The Magic In

No items found.


Use the Harmonics knob to set the intensity of the harmonic generation. Part of Bass XXL's magic is in the musical way it processes your dry track to generate these harmonics. So don't be afraid to turn it up. Engage oversampling for even higher quality.


The Boost knob mixes in the harmonics in parallel – i.e. without touching your dry track. This ensures that you can add harmonics to your low end without messing with its original placement in your mix. Engage Solo mode to listen to the harmonics in isolation.

Your Bass. Your Way.

Increase the pre-delay to preserve critical transients in kick drums or picked bass guitar while still thickening them with Bass XXL’s additional harmonics.
While you’ll generally want your bass to be front and center in your mix, Bass XXL’s mono knob gives you the flexibility to preserve a track’s stereo image if necessary.
Use the Slope knob to determine the curve at which Bass XXL’s highest frequencies roll off. Use a gradual slope for a smoother, more analog feel, or go steeper for a more surgical, digital enhancement.
The Range knob lets you set how many octaves Bass XXL’s harmonics will be generated over. Acting as a filter, the Range knob essentially cuts high and mid frequencies, allowing you to tightly consolidate your bass boost to the low end.

It's Not A Synth

So what is this thing, then? To address some of the confusion, it is not a sub-synth, but a highly specialized effect plugin that takes your dry track and carefully generates harmonics in a contained frequency area, then blends these harmonics into your track. The way Bass XXL creates its harmonics takes advantage of a psychoacoustic phenomenon, which makes our brain perceive more low end, even if there isn't any. This is handy for achieving a powerful bass presence on big and small speakers alike.

With Bass XXL, we have taken this concept as far as we possibly could, giving you extra versatility and the highest sound quality. The plugin is CPU light and doesn't introduce any phasing issues or latency. Unlike a sub synth, Bass XXL's harmonics are derived entirely from your original track. This results in a natural bass enhancement that feels more like 'adding some extra magic' than layering another instrument. Grab the demo and try it for yourself!
