You ordre the midrange drivers at your normal B&O shop.

Dont worry if the labelname are different from the original.

 The label name on the old one was Nokia!, now its no-name 😕 but its the same speaker with the same spec as the "original") If its fits, there is no problem.(you will proberly only  need to adjust the "hook "

You can see the name Nokia on the two old  midrange speakers to the left, the others midrange on right site  are new ones

Hi Bulgarien,

Thanks for all the pictures! Really nice.

Do you really think that soldering all the connections is well worth the hassle?

It is a lot of work disassembling the speakers, and I am afraid that I'm going to dent or scratch them in the process! I have replaced all the capacitors in both the crossovers and the amp, and I think the speakers sound really good as they are now. However, everything can be better!

What do you think? Should I go through with this as well?

 Yes no doubt about that, its not difficult , its take some hour and yes it´s so boring, but you have to understand that the very fine signal to the speakers will see all kind  of connectors as a resistor.

Only with a silver soldering the original, full and clean signal will

Great project! I am very impressed!

Thanks for sharing 

 If I can convince  you and others about the great Penta sound you can get on easy  and cheap way, then I´m happy 🙂

How to remove the  Penta grill, without breaking anything.

Place two fingers on the cloth  precisely where you can feel the clips, and then pull out in the cloth (one or two centimetre), - then the key release  and the grilles suddenly  jump out.

Do the same one the others clips. I think there are 8 at the top and 8 at the lowest grill

When put it on again, just click it on, step by step.

Job done!😎

Hi there, I am new to this and have got a pair of these and limited knowledge.

I understand most of what has been done but if someone could please advise me. Assuming the rest of the speakers are in good order can the amplifiers be removed and then plug into the red and black terminals shown in the pictures. (these are the ones the amplifier output connects to) with another amp rated 8 ohms 150w. My thought is to use the speakers and casing but drive them with a high end home theater receiver using its internal amp instead of the Penta Amps.

Yes - but you might want a pair of Beovox Pentas (without amplifier) rather than the Beolab ones!
