Hi Mindphaser.
You mean you have the BL7.1 placed on the floor and the BV7 balanced on top of it?
If so I would be more concerned about it falling over or airflow being restricted than any potential problems with dust. There will always be a build up of dust on the fan blades (and indeed the rest of the fan) over time, as well as a gradual build up of dust within the TV but this rarely becomes an issue unless severe.
Many thanks for the answer riverstyx :)
Well, the BV 7 - 32 is on top of the BL 7.1 ....but is NOT balanced on the flor 'cause it's placed against the wall with the Walla Bracket Typ. 4095....originally it was shippped with it :)...i bought the BV 7-32 second hand, as i previously specified.
So, time for moving as fast as i can from the Wall Bracket Type 4095 to the Motorized Floor Stand 4091 !
PS: in case i would like to CLEAN those fan blades, would be it a difficult operation?
Thanks again,B&O still rules for me !!!
