Hello, I have BEOCENTER 7000 with a pair of Beovox S75 speakers. I noticed that on one speaker bass dont work at all . I try to switch cables on center to check but it doesent help.So I take the conclussion that something is wrong with the speaker. If you have any idea how to check the speaker please let me know...thank you, Mirko
Compare the bass unit with the one that works. Do both push in easily(they should) If the one doesn't, you have a slipped magnet and it will need repairing - I plan to post a thread about this with pictures in the next week!

Thanky for hint Peter, will check right now...

Looking forward to it
Collecting Vintage B&O is not a hobby, its a lifestyle.
I try this, but it seems that both membranas move the same. I try the gentle push and both seems to move the same ...Then I turn on the music and set up maximum base on center. One base is not working at all.
Take out the woofer (bass driver) and check its connections.

Hello Martin,
can I do this by unscrew all screws from front panell (bass screw) and take out the bass ?

Yes, and you may have to use a little force to brake it loose from the cabinet
Did checking crossover crossed your mind?
Don't worry - be Happy
Bob: Did checking crossover crossed your mind?
Not so fast young man we go step by step here
in fairness Dillen already suggested checking connections
Bob: in fairness Dillen already suggested checking connections
yes ...step by step is greatly apprichiated in my case :), nomather that , some info about crossover will be great :) THANKS :)
connection was checked - the black cable was little loosened from the cable holder on the speaker crown. I fix that with glue, but this was not fault.
I try to see if the cables are fixed, and seems that cables are OK. Input plastic are fixed cables are firmly connected.. I gently close everything back , not to do some more damage .
Unhook the speaker from the amplifier and put an ohmmeter across the woofer terminals.A DC resistance below 8-10 Ohms is to be expected on a good woofer.
(Fixed the typo in the thread title, makes searching easier).
Thank you Martin.. The first purchase now will be ohmmeter :). I newer have one at home , but is seems to be good to have one :)...
I'd liked silnet better Martin ;)
Bob hahahahahah, Sil NET hahahaha...sometimes fingers types something different that brain process.
UPDATE :
I unplaged the box and take it to the BEO lover tehnician who will check and repair it :).. I will buy OHMMETER aniway :)).
