Hello!
Refer to Visaton Grand Rogue website, the speakers can use as standalone subwoofer.
GRAND ORGUE | Visaton
"The bass part of the GRAND ORGUE, on its own without the full-range drivers, connected directly up to an active source without a passive crossover, acts as an excellent subwoofer and can be used, either singly or as a pair, to support music-orientated high-end loudspeakers and full-range loudspeakers down to the lowest bass frequencies and give home theatres the bottom end that they deserve."
Can I build the Grand Orgue as standalone subwoofer by removing those full range mid and high section? So which part should I remove based on the attached drawing?

You’d not remove anything, just don’t make the holes for the array of widebanders. But for a budget of about 300 euro’s for the 8 woofers there will definitely be other options for a nice sub build.

It requires some equalization to function properly. No problem for a cheap DSP or amplifier with built-in DSP.
Where can I get those drive unis for 300 Euro?
The plan I found online, hopefully free of mistake.
As far as I can see, basically anywhere in Europe at least. Prices between 28 and 38 euro's each in a lot of webshops.
That is another 300 euros, and then you're still missing an amp. For the same kind of money (or even less: Behringer NX1000D for instance) you can get an amp with DSP. It won't be automatic, but will be more cost effective. With REW and a mic you can do it yourself quite well.
Note that a single high X-max 18" woofer will have about the same displacement as 8 of those 10" babies 😀 The claimed -10 dB at 16 Hz can be done with a BR or closed large woofer as well. Neither will have a lot of headroom down there though, specially not a RiPole design. And note that down there you'll need to be above the hearing threshold for it to have any effect. For those very low notes that is already at > 80 dB.
In any case, what's your intended use for the sub?
