Hello ASR,
I was not entirely sure where to post this but DIY seems the best option.
The M Audio BX5BT (2025) have a 4 pin din on both the powered master and passive slave for connecting both speakers together.

It’s used by Edifier, IK, Bose and so on and there are aftermarket cables in differing sizes available. My question is are these cables a standard internal construction in regard to live and ground wiring for bi-amplified master speaker to passive slave speaker. Google AI eventually agreed that the same cable could be used for let’s say the Bose M3 or the IK Loud Micro Monitor or the speaker in question the M Audio BX5BT (2025). Can we confirm this?

Yes, just check the pinout with a multimeter set to Continuity mode.

Almost certainly you'll find a 1:1 pinout, as there is no reason to use something else.

Yeah, tried the meter but the prongs are too thick for the pin socket…
 
Paperclips are fine, if you can find a female socket.

You're right!

In that case, an unused, old, broken female XRL plug can come handy to salvage couple of the female pins.

Even the ones used for 12V at PC's would do.

If you try hard enough you can get AI to agree with almost anything. That really isn't a good way to use it. It should be able to give you links to independent sources that support its position. Check to see if those actually exist, actually say what it claims they do, and are somewhat trustworthy.

I found this to be true which is mildly ironic. I don’t trust AI at all.

Other sources have said it’s a standard configuration that is also used by Edifier as well as IK Loud for their monitors.

This maybe a controversial point but I do hear a small increase in noise from the slave speaker in comparison to the master. I believe, at this point, it’s down to the shielding if there is any at all on the stock 4 pin connection cable. I want to combat this with a custom cable using 100% shielded cable namely Van Damme Starquad. All cables going into the master speaker are shielded and high quality copper and the difference is notable. The stock 4 pin is the weakest link.

With this kind of design of Master/slave, I now find this an issue that has become important to negate as much as possible. With individual monitors it’s obviously not an issue.

Did the manufacturer tell you it was a "DIN connector"?
Just to be sure, before ordering, please check the dimensions, shape, whether it has a locking mechanism, and the position of the pins.

DIN (e.g., Switchcraft)

Proprietary standards (e.g., KYCON)

I am still waiting for MAudio to reply.

It is a mini 4 pin apparently. The cable is much like something anyone could find on Amazon.

Much like this one:

I'm not arguing with the conclusion - it would be odd if it weren't wired pin to pin. It was specifically about what the "Google AI eventually agreed" implied about how you were using it.

It seems an unlikely cause, but screening the cable shouldn't cause any problems. The starquad is an odd choice though - isn't the cross section a bit small for a speaker cable? And you won't be wiring it as a starquad anyway.

It’s an option that’s in consideration. The maker of the cable makes them for Quad amps but can also put a mini din in to the mix.

I’m more inclined to go with the Wood Thrush option on Amazon which is for the Edifier RB1700 speaker etc.

M Audio contacted me today and the cost of the replacement cable is…£4.86!
So I may assume, as it is so cheap, that it’s very much a standard configuration that Edifier, IK Loud, Bose etc use in general.

Ordered a 2m from Wood Thrush (USA) on Amazon which has superior dual shielding and twisted cable configuration. A little more expensive but should be more durable at least and the extra 0.5m is welcome.

Once it arrives I will report here with the results and at least it may help anyone whom might wish to acquire the same cable for either the extra shielding and length of which are available in greater, extending up to 10m.

Thanks for the input ASR members.
 
Ok, it seems that the problem is solved which while not a major in electronics and might even be a giggle for the more learned brotherhood it was still enough of an equity to retain a certain caution over.

The cable from Wood Thrush (Amazon US) which is advertised for mainly Edifier and Swan speakers works just fine with the M Audio BX5BT. Only took 6 days to get to the UK.

I did not think there would to much of an issue as basically it’s a standard 4 pin construction on the cable so basically 4 copper wires that have no bias of whatever pin they are connected to with the same connector as the speaker itself.


These are a worthy upgrade over the BX5BT stock cable which is ultra cheap and without shielding which maybe an inside in a Studio full of power bricks and supply’s

There is also another option for those like myself whom know the benefits of good OCC cables like the Furutech FA-220 for example which I use for the connection from my dac to the pre amp and the preamp to the master speaker. It’s an excellent cable choice. So with this use choice matching the slave speaker while not critical to some can allow a notable difference in sound quality if poorly shielded cable or poor quality copper is used.

The Wood Thrush brought an improvement and would satisfy most but if you want to take it a step further then you could try this one from a store on Ali Express which on paper matches the quality of the Furutech FA-220 so your slave speaker will produce the same clean signal as the master. I am not sure how well this is shielded but I have bough cable form this store previously without any issue in quality. I expect for the grade of copper used and construction it most certainly should be.

This again will fit the BX5BT monitors.

Is it worth it for a £169.00 pair of monitors?

It’s a rather large yes from me and while writing this post am listening to notable increase in clarity, musicality, soundstage, sheer bass weight and overall improvements which are of a high percentage over the stock form from power cable to master slave connection and actual input cables.

I also upgraded the op amps on my Fosi Audio ZP3 to the opa828 which also allow superior instrument separation over the stock NE5532 with a tighter cleaner bass too with the Furutech FA-220 cable relish which are known to by many and allow a lot of detail through effortlessly.

I had to use the XL Neutrik 1/4 Jack as the Furutech is around 9mm thick but my friend Stuart at Ultimate Pro Audio LTD UK assembled these with ease. I would advise to avoid using XLR-1/4 adapters and get the cable made professionally, it pays off!

Op-amp rolling doesn't work. You have been told this countless times but keep polluting the forum with nonsense. Please stop.

Does Op-amp Rolling Work?

When I post my last video on review of Douk A5 amplifier, I mentioned that rolling (changing) op-amp ICs in there is fruitless. I got have a dozen comments under that video in youtube asking why so I thought I experiment again with the A5. Note that I have done the same testing with both DACs...

I think you should stop now my friend and relent as well as others whom use my posts for their personal argument. Companies, people all over the world as well as myself know that op amps differ in sonic characteristics. I, as others have enough experience to be able also to differentiate in blind tests. Do not turn my post into another op amp argument, please leave that to the thread link you have posted. Thankyou.
