Hi all,

Would anyone have information on how the internal foam sound absorbers were placed in the R105.3? I have a second-hand pair and unfortunately someone 'played' with them - some of the foam is surely missing. Would anyone know if the placement and foam sheet dimensions would be the same as how the R104.2 was done? My brother has a pair of 104.2 that I can look at. I need the info for all three "Bass chambers" - top and bottom 'acoustic suspension' portions, as well as the middle 'bass reflex' portion...

TIA,

Clem

Hi Clem_o,
when I have gotten off the my 105.3, I have found three sheets of absorbent acoustic in the closed hollow of the b200s.
In the superior hollow the three sheets had put without any system of protection of fall for gravity in the woofer. Strange. The absorbent material is in sheets of white synthetic wool of around 25x50x5 cms.
The central hollow has covered on the three sides of sponge, except the side loudspeakers ( low-mid, uni-q ).
To get off the base of support of the loudspeaker, it is necessary to simply unscrew the conic points and then to screw to their place a long pivot. This pivot entering pushes out the base one angle at a time.
best regards.

Hi Sandro,

Thank you indeed for the informaton!! After much experimenting I actually arrived at a similar configuration, though I had some very good "clues" from the 104/2.


Cheers!
