Hi guys,

I'm Having a set of Beolab 15 & 16 installed in a new bathroom, and my B&O dealer suggested to use two Cat7 cables for each speaker. However, I overheard a person at another B&O store suggest to use speaker cables with four wires each (4-leder in Norwegian). I'm not able to consult with this guy to get an explanation.

Each speaker has an RJ45 input for "Control" and 2x2 inputs for "Speaker" which I suppose is power, i.e. + and - for TW and Mid on the speakers and + and - for each of the two units in the sub.

Do you have any advice on what cables to use? I suppose that the plugs will have to be installed on the cables after they've been placed in the wall.

Pretty simple - run one 4-wired cable (with the special connector) and one Cat7 (with the RJ45 connector) to each speaker!

There is a tv - and there is a BV.

Thanks a lot! Though I fear I am starting to get very annoying now: Should I expect the special connectors to be included in the speaker /amp set? And would it be better to use two 2-wire cables for the Sub, where the speaker terminals are almost 20cm apart?

This dealer is clearly an idiot, please name and shame.

He should have answered all your questions!

You are not getting annoying.

But your dealer has (as StUrrock writes) revealed himself incompetend.

Of course he should have provided the cables. That is - if you made a really good deal, you now will have to buy these extra.

Which - of course - your dealer should already have offered.

The speaker cable terminal blocks are supplied with the amplifier 1 and respective speakers. This is a basic installation, I fear that if your dealer is struggling with this what else have they not been able to do for you?

I normally use the pink QED 4 core cable and splice it and the subwoofer.

The CAT7 cable provides power to the speaker and also data back to the amp on how far each speaker is so it can calibrate each speaker accordingly.

Last month I bought the same set up (ex demo). It is all packed away in bubble wrap waiting installation. I suddenly thought I better check i have all the connectors and I do. The dealer was excellent and gave me all the cables free as once he'd disassembled the display he said he would have no use for the cables. All connectors present and correct,.

Here is a photo of the cabling given to me, it is fairly heavy duty copper stranded.

It might be a little unfair to "have a go" at the dealer for not supplying all the correct connectors on an ex demo setup as his installer would have dismantled the display and often the dealer is not an installer so won't know what parts come in the pack or which are extras. When I bought mine, the dealer said he hoped everything was in the package but if anything was missing to get back to him. If the dealer provides everything once you ask there is not an issue. If he is unhelpful or tries to tell you standard part are extras - that is a different story.

Thanks a lot all of you, really appreciate it! I'll get the speaker cables myself somewhere and let the dealer provide the CAT and do the terminals and the calibration.

I got the impression that at least I will get a brand new set to the same price as the demo set will all the issues, but we'll see.

Hi HC,

Apologies for the very late reply to this thread, I trust that you got your Beolab 15/16 speakers connected and working at the time of posting.  I just happened upon the thread today by accident, so I thought I should reply to Millemissen's earlier post to confirm that I'm always happy to help with cables or connectors for these speakers.

If you (or anyone else reading this thread) needs assistance, I keep these cables and connectors in stock ready to ship.

Kind regards, Steve.

Steve.
