I measured how the sat. crossover ot the ESI Aktiv 10s works (100Hz HPF) and it turned out that it has a high pass filter set to 50hz (6 dB/octave) and not 100hz.
In this case, the subwoofer is muted, and I only use the satellite crossover function. Тhe speakers are Yamaha HS8, and the drop is due to the placement of the speakers and the shape of the room.
Blue line: sat. crossover off
Black line: sat. crossover on

After adding ESI Aktiv 10s + EQ correction the low end improved.

In psychoacoustics mode it looks good.
Measurements were made at 80 dB SPL.
EQ adjustments are 3 points, via the TotalMix Equalizer (RME Babyface Pro FS)
The reason for the dips and spikes around 1kHz is the desk, unfortunately I don't have any more EQ bands and I don't want to use other apps like Equalizer Apо because it's not convenient to work with them because I have other devices to switch.
The room has been somewhat treated, about 50 pieces of rock wool were used in bass traps and absorbing panels.

When placing the subwoofer in the center of the room, i.e. between the two speakers, it overexcited the frequencies around 90hz, and the sub-bass around 50hz was missing, and in my case, placing the subwoofer about 90cm to the right of the right speaker and 1.8m from the listening position was the optimal option.
I'm thinking of buying another one of the same subwoofer and placing it on the left side, and I hope to improve/balanced the low end even more.
Another screenshot:
Green line: measurement taken 2cm from the subwoofer.
Yellow line: measurement taken from the listening position, the subwoofer is positioned to the right of the right speaker at about 1.8m from the listening position and 90 cm from the right speaker , there is a delay of about 7ms.
I think it's ok for the price, there are a few resonances up to about 300-400hz, but they don't interfere with the overall sound picture.
The measurements are not professional, they are simply personal and indicative!
