There could be an adjustment that you have not found yet....Tone/Equalizer.... for the bedroom speakers. I am not familiar with this particular system, but Bose is notorious for using reflected as well as direct sound to enhance the listening experience. A different setup, (size of room, wall placement as well as object placement, speaker angle, etc.) will produce different sound and is usually compensated for by adjusting the tonal quality as well as any delays that the system might offer. Again, I'm not familiar with that particular system, but the higher end stuff usually has adjustments to compensate for room and speaker-placement differences. Just some thoughts.....
