Koning,
with the DSS-module you can simply regulate the intensity of the BL2. In my living room 22 square meters it is operating approx. with less 50%.
However I personally even think the BL2 is better for music than for movies. I have heard the BL11 in combination with the BL8002. I have spoken to 4 different B&O experts. The BL11 would not make a huge sence in my case. The BL8002 would not benefit from the BL11.
I like a solid bass. So the BL2 was the best choise for me. And I`m sure, not all people praising the BL11 are honest to themself.
BL2 best choise for me, of cause with music.
