That’s fine. The most important thing is that the speakers are made to work again – I think we can agree on that!
However, it’s interesting you mention RL140s. I acquired a pair last year and one was fitted with the original two woofers that needed re-foaming, and one was fitted with the two B&O-approved replacement drivers, which had rubber surrounds.
After repairing the original woofers, the sound was distinctly unbalanced, with the speaker with the ‘new’ woofers producing noticeably more bass. To restore a balanced performance I ended up putting one new and one old woofer in each speaker.
As an aside, I almost wish I hadn’t bothered. I’ve always been secure in my opinion that I didn’t really like RLs. Trouble is, no-one told these RL140s – I haven’t listened to anything else since I finished them over a month ago. I had originally planned to sell them once repaired, but that’s not happening now!
Im not totally agreed. You had beovox rl60 who had foam surrounds, after that rl60.2 with rubber surrounds. For durability i would take rubber surrounds. But that is my opinion. I would not re-do the process each 15y because it’s time consuming
Yes, but they were different drivers with different performance and, as a result, the RL60 and RL60.2 crossovers are different to account for the drivers’ different sonic characteristics
I personally feel that it is always best to replace foam surrounds with foam and rubber with rubber.
Agreed – re-foam not repair! But do not opt for rubber surrounds if your originals were foam – stick with the original foam material otherwise you will alter the characteristics of the driver.
The correct foam surrounds from Audiofriends are here:
I’ve not used Audiofriends personally – I usually use Good Hi-Fi and they also do the correct S80.2 surround here:
Firstly, I would like to add my voice to all those above in thanking Lee and Keith for the running of Beoworld, and to Steve for sponsoring it. The site is an invaluable resource for B&O nuts like me but I have also been well aware that traffic has been reducing over the years, which is very sad news. I’m active on many hi-fi forums and, predictably get asked lots of questions about B&O which I’m more than happy to answer, but I always try and point people in the direction of the site.
As to Gold membership, it’s something I consider essential for access to the magnificent repository of service and user manuals. The prize draw is a lovely bonus and I have been lucky enough to win on several occasions, but if this were to drop to once a year or even vanish altogether, then it wouldn’t affect my membership decision – I’d still stay Gold. Like chartz – I’m not going anywhere!
I would also personally be more then happy with an increase in the cost of membership but I do appreciate that this may well have the effect of putting people off – you can’t win in this one!
In my own small way, I’d like to help by making a donation to the coffers and Lee – if you do decide to continue with the draw, please drop me a line as I have some items in the Smith Beocollection that i would be more than happy to donate for the next one.
I would also not use the speakers again until you have given the amplifier unit a thorough once-over. Two blown tweeters and smoking resistors in a passive crossover suggest to me that the amp could be putting out DC.
If it is, then it’ll just keep blowing your tweeters and crossover components every time you replace them.
Just an update – I found pictures of the MS150.2 crossover online and it appears that mine have been half re-capped! However, one of the original capacitors has broken and one of the replaced caps appears to be the wrong value.
Consequently, I have done what any sensible person would do in this situation and ordered a full capacitor kit from Beoparts!
Would still be keen to know if there’s a service manual out there, though.
Not specifically Beogram 4000 related, but Multicare came and visited us last year to carry out a safety recall upgrade to our Beovision Eclipse and I got them to update our BL90s to the latest software version while they were there.
Excellent communication and service all round, so a thumbs-up from me.
They’ve also been very helpful in contacting B&O HQ regarding an issue I have on the B&O iPad app with the Lab 90 control, but this remains unresolved as yet.
If you’re using the digital output of the Beosound 9000, then the CD is the only source you will hear as that’s the only one that has a digital output.
You will not be able to output the radio or anything plugged into the AUX socket through the digital output as these are both analogue signals, and the 9000 does not have an inbuilt ADC to digitise these.
In addition to the point above, some ‘continuity’ meters only beep when below a certain resistance. The filament of the lamp will have a resistance and if it happens to be above this point, then your meter won’t ‘beep’, giving the impression that there is an open circuit.
No big issues on these in my experience. The motors can make ticking noises but this can be remedied, and I’ve had a similar Beogram 2000 do some odd things when dirt got behind the front panel and into its start/stop switch but other then that, they’re pretty reliable.
Lovely decks – go on, treat yourself!
I’m working on a big speaker drive unit re-foaming session currently.
The two drivers at the left rear are from RL140s and I’m sure you can all work out where the SIXTEEN midrange drivers at the front came from!
I was hugely impressed by the Beolab 28s when i heard them – one of the best speakers B&O have developed in years (outside of the 90s or 50s, obviously).
However, I would say personally that they still fall a fair way short of the Beolab 5s’ performance.
My main loudspeakers are Beolab 90s and I also use Beovox MS150.2s regularly.
Hi Adam, that is indeed superb! which amp do you use for the MS150.2s? ps/edit: how to get out of the quote mode?
edit 2: ah it works, thanks Guy!
I obviously have a Beomaster 8000 but I mainly use the MS150.2s with a Yamaha C-5000 preamp and M-5000 power amp
What a wonderful selection of prizes and hearty congratulations to all!
Very envious of Martin’s boot bag!!
I know the chap who made the original post, and he and I have been in conversation about these. I hope he won’t mind me reproducing part of a text he sent me last night here:
“….these things sound fantastic!”
Looks like we may have another convert… :o)

I agree that the Theatre does look a bit odd but, in contrast, of the items that the OP mentions that he likes, I’ve always found the Beovision 5 to be an odd looking thing that permanently seems to be about to topple over backwards. Even worse, I think that the Beolit 12 is one of the ugliest things ever to bear the B&O name!
Horses for course, as they say…
When I worked in loudspeaker design, we would often buy competitors’ speakers for evaluation purposes.
When done with them, they were either donated to charity, or offered to staff for a nominal sum.
