Jeg har et sæt Beolab 6000, hvoraf den ene skal ha udskriftet begge basenheder. Jeg overvejer dog at bytte basenhederne i begge højtallere med mindre prisen tilsiger noget andet.

Mit spørgsmål går på, hvor man billigst for skiftet disse enheder evt. køber dem og selv skifter dem og hvad skal man forvente at skulle betale for disse enheder..

Nærmeste Bang & Olufsen forhandler. Jeg mener ikke at de er så dyre. Og de er lette at skifte selv.

M.v.h.

Et godt råd er i øvrigt: JA! Byt alle fire på en gang!

Hvis du vælger at bytte dem selv, så kan det være lidt tricky, hvis man ikke har prøvet det før. Men her er en rigtig fin beskrivelse, fra Beoworld.org:

"The original driver surrounds are made from a very flimsy rubber/urethane material. Replacement foam surrounds are very much stiffer and your speakers will have little or no bass! I have examples of refoamed 6000 drivers which were in a pair of speakers bought by me when I was in gullible mode!!! They sounded rubbish.

In my opinion, ALL the drivers MUST be replaced.

I believe that B&O advises that the speakers should be dismantled from the bottom up. ie Remove the amplifiers/power supply first and then the woofers. I prefer to start from the top.

Here is the advice I gave to Jimmy, sent by email but not private.

You need to remove the front panels starting with the top one.
First remove and disconnect the tweeter (2 screws)
Then remove the top panel (6 screws) by levering gently from the top of the panel. The sealing under the panel will act as a glue so expect some resistance.
Then remove the first woofer and disconnect it (4 screws) followed by the second woofer (4 screws).
The captive screw thread “widgets” may slide out of alignment but you can slide them back on re-assembly.
Reverse the procedure to rebuild.
You will probably find that the new woofers have been calibrated by B&O as +0.5dB and instructions are given to adjust the outputfrom the amplifiers accordingly. The process involves an audio signal generator which I do have.
However, in my opinion, adjustment is not neccessary and the small base boost evident on real listening is to be very much appreciated.
This is my opinion only and there will probably be those that disagree. It's a free country!!

Regards Graham"

Var det ikke kun i mk1 at enhederne gik i stykker?
Nogle forhandlere kan opgradere til mk2 for ganske rimelige penge.

Jeg tror du tænker på BeoLab 8000, hvor der findes et MkII opgraderingskit, med nye basenheder og nyt amp-modul.

Korrekt, det er selfølgelig 8000 og ikke 6000 - min fejl.....
