Kokane81:

After having some of these woofers replaced there was more to it then just swapping faulty woofers.

depending what serial number the speakers are you will need certain caps and resistors changing. (some of these being surface mounted)

then they needed to be re jigged using an oscilliscope.

Plus the woofers werent badly priced at £70 for 2. which in comparison to the price of a new speaker isnt a lot.

You are confusing the woofer (bass speaker) with the tweeter (treble/mid range).

Unless the situation has changed recently,there are no extra components to replace with new woofers and full instructions are provided by B&O.

There are some components to replace with new tweeters. These are used to improve the protection circuit so that, in theory, the new tweeter does not blow again. Again, full instructions are given in the box.

Did you get the caps and that done at a b&o retailer?

How old are your speakers?

Hi there, if you still need them: http://www.ebay.co.uk/itm/Rubber-repair-kit-B-O-Beolab-6000-4-pcs-glue-/250930223926?pt=UK_AudioVideoElectronics_HomeAudioHiFi_HiFiSpeakers&hash=item3a6c9b5b36#ht_583wt_986

I have installed these on mine and they are great, make sure you dont use too much glue and that after you have fitted and glued the rings, that you play music through them to ensure that they are seated correctly in the proper position.

If you need any help, let me know.

Hoping to get a reply since this thread is old. I have a B&O system. I have severail pairs of speakers among these, two pairs of Beolab 6000 which have developed the rattling sound characteristic of blown woofer/midrange drivers. I need to replace these. The B&O dealers inthe USA I have so far contacted do not sell the individual drivers. I am a DIY person and it should not be a big problem for me to replace the (really cheap and cheesy) drivers. How can I get these and how much would these cost me? I need 4 or may be 8 ...

installed that rubber surrounds from goodhifi on my beolab 6000 speakers and they do sound good if mounted correct. I see no reason to buy new woofers, but it's up to anybody to decide what to do with their speakers.

What about These ones? http://cgi.ebay.co.uk/Rubber-repair-kit-B-O-Beolab-6000-4-pcs-glue-/270710128724?pt=UK_AudioVideoElectronics_HomeAudioHiFi_HiFiSpeakers&hash=item3f0794c054#ht_500wt_922

Are these going to give good sound? as the listing states that they are rubber and not foam?

Ok, thanks for your advice. I think that probably the new drivers from the B&O dealers is my best option as i want to get back the beautiful rich sound that they were producing before, and a lack of bass would be awful for me, as that is the key part of the music.

Its a shame about their pricing. Over £120 for the 4 woofers alone. Will have to do a bit of saving up.

ronnie1995:

joeyboygolf, please could you share your advice?

It would be much appreciated as i still need to repair my ones.

Also in your opinion, which is the better option?

Refoaming the beolab drivers or buying new drivers from b&o shop?

Many Thanks in advance

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!!

Jimmy1963:

I tried to take the unit (wofer) out, but after retrevieving all 4 screws it seems that they were stuck/glued to the base. Could you please guide me on this as I have no previous knowledge on the subject and there are no dealers in my country.

Cheers

I have replied to your email, Jimmy

Try another dealer for spares. I have just fitted four new woofers to a pair of 6000's at a cost of £120 or so. Easy job which requires a torx screwdriver only. Takes about an hour to replace all 4.

Part number is 8480232
