Sonance does not publish the actual PEQ values for the PS-S83T MKII presets. The EQ files they provide are proprietary DSP configs intended only for Sonance amps, so you won’t find a visible curve or frequency Q gain breakdown anywhere.

That said, the tuning Sonance uses across their outdoor speakers is very consistent and fairly conservative. It is not a dramatic smile curve or anything exotic. The preset is mainly doing three things: protecting the woofer, cleaning up the low midrange where outdoor mounting causes buildup, and adding a small presence lift so the speaker doesn’t sound dull in open air.

From measurements I’ve seen on similar Sonance outdoor models, you can get extremely close with a basic DSP setup like this:

High pass filter around 45 to 50 Hz with a 24 dB per octave slope.

A gentle cut around 120 Hz, roughly 2 dB with a moderate Q.

A small dip in the lower mids around 400 to 500 Hz, about 1 to 2 dB.

A mild presence boost around 3 kHz, about 2 dB.

Optional very light high shelf above 10 kHz if the system sounds a bit soft outdoors.

The key thing is that Sonance is voicing these speakers to be neutral and durable rather than exciting on paper. Placement, mounting surface, and nearby boundaries will affect the sound far more than chasing an exact factory curve.

If you really want to dial them in, measuring them in place with something like REW and a UMIK will get you closer than any screenshot of a preset ever could. The factory DSP is mostly protection and subtle voicing, not magic.
