Speakers least affected by room acoustics

not really except listening in the near field to minimize the effect.....

Google Spatial Audio. Check out the M3 and M4 Turbo S. These are open baffle speakers, not enclosed floorstanders.
They would not need acoustic treatments on the wall behind them or any bass traps. But you should still listen in the near-field.

How large is your room?

12 x 20 with speakers on the long wall

The Spatial speakers look interesting. I talked to Walter Lieberman and he recommended his Emerald Physic’s as they are open baffle too
