Because a room the size you are describing would be too small even for necessary treatment depth.
For example my room is 450x305x235 cm before treatment. Bass traps are 50 cm deep on the front wall, 30 cm deep on the sides and ceiling, and 60 cm deep on the rear wall (all surfaces are fully covered except the floor, and there are also slats).
K+H O300 monitors at 30 degrees result in tweeters that are 44 cm from the front bass trap (94 cm from the front wall). The listening position is 159 cm from the front wall, so about 64 cm from the center of the room.
When putting the measurement microphone closer to the front wall, the low frequencies increase in level, but the ideal position (for bass) is too close to the monitors.

A multisubwoofer setup ( at least 4 subs or more) with digital management and minimum phase EQ can definitely work wonders in smoothing out the bass response and decay, but you still need some treatment in the space. Also if the room is tiny, using 4 or more subs will not be possible because of the depth of the subs alone. Also if you need to drive the modes in the corners, there can't be a door in the corner obviously.
As a test, I can try to use old 5" compact monitors as satellites and the K+H O300 as "subwoofers" (on the floor, with the driver facing the front wall), with whatever software DSP processing (crossovers, all pass filters, delays). Compared to the current setup, it allows to sit 22 cm further from the center. If it works well, then I can get more adapted monitors.
Otherwise, there is not much to do for improving this room I'm afraid.
