Considering the side of your room, (Basically a small office/bedroom) you're probably going to be better off looking at working with a near field setup?
IIRC, the Spatial towers are quite large, in both width & height, and require, at minimum, 3ft from the front wall. Leaving you with 8-9ft of usable space. When in a listening position, but may sacrifice some width in the soundstage.
Ideally, you're going to need a bigger room for a full OB-setup, tho its not impossible if you want a one-and-done sollution.
For ease of placement & floor space, the NX-Studio will probably be your best bet, & will work well in smaller rooms and can be placed closer to the front walls.
You can then augment the bass with 1 or two sealed subs, as space allows.
If you're less picky about placement & dont mind giving up some floor space, you could probably squeeze in a pair of NX-Otica MTMs sitting on top of a pair of dual H-frame towers.
Any of these options will sound amazing, but will definitely reward you greatly in the future should you ever have a chance to move the setup into a larger room in the future..
Just my 2 cents! Hope it gives you some ideas to consider going forward!
