Ok, so I checked with my local Bang dealer, and sadly, the modification kit is no longer available - at least not in the Nordic countries. A strange thing happened by the way; I replugged the speaker today to try out my newly aquired Beogram CD 4500 (birthday gift from wonderful and understanding girlfriend), and it now seems to work! Question is for how long. I'd better go find another pair of RL60's to use for spare parts.

Hi, I've recently had the same problem as you with my RL60s. To answer your question directly the straps come off very easily. Each one is attached to the casing with one screw on the back. To remove the strap just undo the screw and slide the strap off (carefully!) to one side. Opening up the speakers is then fairly simple. Just undo all the screws you can find and remove the back casing. I am a complete technophobe and was nervous about doing this in case a broke something but I managed it easily so if I can do it I'm sure you can!

With regard to fixing them, I don't think a spare set of speakers won't be much for sorting the ABR plates as the majority of these will have the same problem unless they have been refurbished. The only way to get them fixed is to have the ABR plate refoamed. Beoworld member Dillen should (I think) be able to do this for you if you don't want to do it yourself (he is based in Copenhagen). He has just refoamed the drivers for my RL140s.

Sadly when I opened up my RL60s I discovered a previous owner had just taken out and discarded the ABR plates to stop them rattling so mine were unfixable (unless anyone has a spare set?) but you shouldn't have that problem!  

Hope this helps.

you don't have to use ABR plates on RL60 speakers, they were a design failing that B&O resolved 10 years later by offering an "RL 60.2 Bass Port Kit"  part number  8480128 for about 100 euros, the kit basically converted the old RL60's to the later RL60.2 design, sadly the kit is no longer available from B&O

However, Mike at Speaker Hobby has modded his RL60's to great effect

So that could be a better bet long term to consider  !

Also, do remember if you do any work on the RL range of speakers to upgrade the caps to 250 volt polycarbonate capacitors in the filters, they sound better for it.
