The Bass XXL Upgrade from Bass XL Black Friday deal is 48% off at $13, ending Dec 7, 2026, for Denise Audio's bass enhancer plugin.
This is an upgrade product for owners of Bass XL. The full version of Bass XXL is also available.
The plugin is built to help you get a fat, smooth bass that still reads on earbuds and small speakers.
Bass XXL uses a proprietary algorithm that generates extra harmonics above the bass frequency you want to enhance.
It leans on a psychoacoustic effect: the brain reads sub bass largely through its harmonics, not through the lowest frequencies being produced.
The maker contrasts this with "bass boosters" that act as blunt, destructive EQ moves or sine generators. Bass XXL builds a parallel signal of higher harmonics and leaves your dry signal untouched. The maker says this avoids the phasing issues that tend to affect this type of plugin.
A dynamic visualizer shows how the plugin reacts to your sound. The dry signal is the blue line and the harmonics are the white line.
There are 48 presets, and you can save your own. Tooltips explain each feature when you hover over it.
The maker also reminds you that good bass starts at the sound source, and positions Bass XXL as the effect for taking it further.
On Mac, you need OSX 10.11 or newer, 64-bit only, and it runs natively on Apple Silicon. Formats are VST, VST3, AU and AAX.
On PC, you need Windows 7 or newer, 64-bit only, in VST, VST3 and AAX.
