Speaker cables (biwiring)

@east electronics
The paper I mentioned in #14 was brought up in a conversation, but I never read it.
Anyway, I think that if an exact common zero-reference for all the sections of a crossover is considered important, the use of a single cable leading right inside the speaker makes sense: Why place this zero-reference two+ meters away inside the amplifier, connected via separate cables to the different crossover sections?
Indeed we agree
the only point is that configuration like that for sure drive systems to parasitic oscilations
It might be a good idea based on the low impedance ground but needs work to be implemented properly

you see our load in speakers is reactive things come and go
In biwiring what ever returns to the low impedance ground is different and a friend said that in this case middle an high returns do polute bass cable and visa versa and that is the benefit of biwiring. remember that in biwiring signal feed is the same but load is different per cable
Indeed this is possible since both cables return to a low impedance potential zero or audio ground

Perhaps, but entirely correctable in EQ if significant. Not something to be left to chance.


Are we talking characteristic impedance here?
Eq in a hiend system is just a joke
It can only correct volume at some frequencies but will effect signal quality , add noise in the signal and add unnecessery color in the system .
Most of times problems in a system are phase oriented and NOT level of frequency A or B
So eq is the totaly wrong approach .

Yeah. And there are more and more jokers in the audio industry — JBL M2, Klipsch Jubilee, Grimm Audio LS1, Kii III, Dutch & Dutch 8с, Genelec 8381, B&O Beolab 90, Steinway Lyngdorf...

Or maybe the cables that made physics professors rethink physics are a joke?

All claims are wrong in 2025.

I guess these problems can be solved with different cables in biwiring? I'm kidding.

Let's also think about beginners sometimes, please.
Why don't you give some examples of how it's done and how much it costs?
I'm serious and a beginner in this case is me. 😍

Could you please clarify the question?

Price of high end speakers is ridiculously high, but that's independent of the use of EQ in such speakers, passive ones can cost even more (often without objective reasons). But the prices of equalizers and active crossover solutions have become very affordable in recent years, and many of them have high sound quality, work with both amplitude and phase (FIR), show low noise levels, and when properly applied, only reduce the coloration in the system.

Many EQ solutions cost significantly less than high end cables, which of these has a real effect on the sound and which are placebo level? 🙂
 
Is there any rule that says that in bi wiring the cables MUST be of the same type and why ?
In my simple opinion there is no reason why the two cables must necessarily be the same.
The fact is that like all things that concern Audio and which have no scientific proof to support because no one would think of spending money on that, then some (none of those who posted here) feel entitled to mock and deride those who practice certain choices of theirs.
In my opinion the fact is also that bi-wiring is already a debated topic and not easy to deal with even just with your own ears, changing also the brand of cables then only complicates things further, at least in theory.
I use bi-wiring with two cables of the same brand and the same length with my Snell TYPE D and my ears are satisfied with the result.
I could also add that since I have a huge admiration for their designer Peter Snell and that he had foreseen bi-wiring in the speaker systems he himself designed, I don't care too much about the detractors and I think that if the very talented designer has foreseen it, he must have had his own good reasons to do so.

It is certainly a nice business to get into, testing different cables in bi-wiring, I would like to have the motivation and the time to do it and evaluate what my ears perceive. 🙂

Have a nice day with your experiments/tests!

That's exactly what I'd like to hear from you.
Give me an example of an "EQ solution", I swear I really have no idea about it.
I'm thinking that you're not referring to an equalizer, of course, but to "something" that in 2025 would be worth trying for its intrinsic quality.
At least that's what I deduced from your statement.
And I'm genuinely curious to know, to learn and to evaluate if it could be useful to me. 🙂
At least in broad terms.

But there are a lot of such products.

Many stereo amplifiers or DACs have an EQ on board with advanced features and without the problems mentioned. Just for example, I'm using Lyngdorf TDAI-1120 which has advanced tools for building a crossover in a two-way system or with a subwoofer, with several layers of available equalizers and not bad room correction, although I don't use it. A large number of modern amps have similar features, have Dirac or other room-correction tools, plenty of PEQs, and all with excellent quality. NAD, Anthem, Trinnov etc. Or DACs like RME ADI-2, Topping etc.

On the other hand products more for the DIY, such as DEQX, MiniDSP Flex or Ncore plate amps with DSP. You can even just use a studio-quality equalizer on your computer, or an EQ/convolve in the Roon - and that won't mess up the sound either, the transformations will happen in the digital domain.

Interesting.
I'll delve deeper into the numerous hints you have given us over time.
Thanks. 👍

However, I'm not sure that the different perceptions that one experiences within their own four walls and with their own system when listening to different cables in bi-tri-wiring are comparable and/or reproducible with what one gets from digital EQ managements, but I could be wrong.

For the start, it's worth doing at least a sort of blind test (e.g. have your partner switch cables from time to time, and you guess when which one was on). If you manage to guess better than chance, then you can start thinking about what exactly affects the sound. But if not...
