It doesn’t matter if your room opens up to the rest of the world. It only matter how far you sit from them, which is ONLY 10 FT.
OK, do this one simple TRICK. On your TRIMS (speaker channel levels), manually increase all of them by 6dB. So if your Front Left is at 0.0dB, increase it to +6., etc. Then tell us if you FEEL the power is better.
