@Jeff (and others who might know),

How to terminate the Neotech NES-3003? it has 4 individual cables. each has core and shield, and then there is an overall shield.

I originally thought just treat each individual's core+shield as one. and then put together red+white and blue+black. overall shield goes to -ve at source end.

Doesn't sound too good though.

Are there other methods?

I can't help but will be keeping an eye out for answers here.  I had the exact same question about the same cable.

Maybe the description here will help:

Best,
Anand.

The Hificollective instructions are incorrect. They ask to isolate the inner shield and if we do that we end up with just a 18awg cable, and then wasting a bunch of silver plated inner shield/spiral.

We do not suggest termination geometry on our website because we cater to the DIY.  Everyone has their own way of....  However, we have an opinion.  We have merely learned to refrain from giving our unsolicited opinion 

I have rewritten the same instructions below in post #16.  Hopefully most folks will find it less confusing.

That's very interesting way to terminate it! I might try it out and see how it sounds. Any reasoning to it?

I am using WBT 0645 connectors.

@Jeff (and others who might know),

Connectors are a source of electrical and money loss, I could solder the core only to the amp circuit or speaker or xover, let the shield alone.
Seems this is my unsolicited opinion

I see self amplified bluetooth speakers in your future.

I afraid young audiophiles will accept it without think twice.

Well no response from @Jeff but I went ahead and re-terminated the NES3003, putting the 2 innercore together in one banana plug, and then the 2 inner shields in another banana plug. Kinda like biwire configuration, but not actually doing biwire. this allow experimenting with different terminations. Friend and I both came to the same conclusion, with best to worse sounding:

- red/white core together with blue/black core (and vice versa) (as Jeff suggested)
- cores only, leaving inner shield disconnected
- red/white core together with red/white core

I have no explanation, just the results from listening.

My apologies for the late reply.  We were trying to get shunt down for two weeks the day after your post. 

I'm not sure you tried it the way I suggested.  For a better understanding, research DIY speaker cable receipts Jon Risch.  We applied that approach to the NES-3003, and really liked the result.

If you have not tried this connection, please do.  Other things to consider.  When using set screw connectors, you should always use the appropriate size crimp sleeve.  This will make a better connection, and protect the wire from damage.  With this setup, a spade connection will be better.  If a spade absolutely can not be used, use a better banana.  That 645 leaves a lot to be desired.  It would not be hard to find a banana with a 50% increase in Copper content without that thick Nickel subplate. 

BTW, the best, and fastest way to acquire tech from me is to email me directly.  The address is on the Contact page at my website

Jeff if i send you a single run of 5feet neotech 3003 speaker cable with neotech banana plugs can you terminate them?

[Jeff]

I'm sure we could.  Email me for the particulars.  I seldom get notice thru this site.  See "Contact Us" on our website.

Ho @jeff and all,
I will buy Nes-3003 as soon and i Need to do biwiring configuration (only ok speaker side).
Do you suggest to use white/black (fat core) to low frequencies and blue/red (thin core) to high frequencies or do you suggest to mix them?
And how do you suggest to combine shields for the mix?

Thank you so much helping me!

Hello,

Can someone please provide details on how to terminate the NES-3003 mk2 cable for a bi-amp setup?

Thank you,
Marius

[rhale64l7]

Sorry I know you didn't get a reply on this. I was wondering the same thing but I want both ends separate. I don't want them combined at the amp end. I want two separate runs at each end. Any help out there?

[Jeff]

As mentioned above, I seldom get notice from this site. I have not seen post 13 & 14.

While one should have been able to deduce the proper procedure regardless of the final configuration from my original instruction 5-6 years ago (post #4), I have decided to re-describe the principal.

While several options/conventions are possible, this is how we terminate NES-3003:

>Red core + White shield = High-pass Positive.
>Blue core + Black shield = High-pass Negative.
>White core + Red shield = Low-pass Positive.
>Black core + Blue shield = Low-pass Negative.
>Cable shield via a small drain wire to the amp side Low-pass Negative.

If you were going to single wire like jmpsmash above, then you would:

>Connect the High-pass Positive to the Low-pass Positive on both ends.  And then, the High-pass Negative to the Low-pass Negative on each end.

If you were biwiring a speaker and wanted to single wire to the amp (like most folks), you would:

>On the amp side of the cable only, connect the High-pass Positive to the Low-pass Positive then the High-pass Negative to the Low-pass Negative.

I would not biamp with this cable.

The Hificollective instructions are incorrect.

You need to watch the corresponding video. The blue and black shields/conductors are connected to the overall shield at the amp end. The red and white are not connected to either the conductor shield or overall shield at either end. The video shows step by step how to have single pair at the amp end and biwire at the speaker end.

Based on making RCA connectors with signal/return/shield, that makes sense to me.

Apparently the answer Neotech gave HiFiCollective when asked how to connect the 3003 up was "cut off all the inner shields".

Hope that helps the OP. I'll be making them up as a bi-wire on both ends setup in a few weeks and will share feedback then. My approach will be-

- Black Core + Shield + outer shield = Low negative, amp end (small drain used to connect core & shield to outer shield)
- Blue Core + Shield + outer shield  = Hi negative, amp end (small drain used to connect core & shield to outer shield)
- Red core, no shield                       = Hi Positive both ends
- White core, no shield                    = Low Positive both ends

[Pivotal74]

this is how we terminate NES-3003:

>Red core + White shield = High-pass Positive.
>Blue core + Black shield = High-pass Negative.
>White core + Red shield = Low-pass Positive.
>Black core + Blue shield = Low-pass Negative.
>Cable shield via a small drain wire to the amp side Low-pass Negative.

I know each to their own etc. but above makes for an excessively complex build and I wonder can you share the logic of it. Does it assume two wires at the amp end i.e. all four brought together into two overall conductors?

I personally can't see how it would work for biwire both ends as your taking 4 shields and cross connecting them to 4 different conductors and an outer shield... (brain hurts even with the cable in my hand).

You bring up a good point.  Fashioning this cable is not for everybody.  We do offer termination services.  However, I do not think your going to help the OP 7 years later.

I wonder can you share the logic of it.

Well, cross connected coaxial speaker wire is not new, and it is thoroughly discussed other places on the net.  Try googling it.  "We" do it this way because we found it sounds best.

Does it assume two wires at the amp end i.e. all four brought together into two overall conductors?

From above:

If you were going to single wire like jmpsmash above, then you would:

>Connect the High-pass Positive to the Low-pass Positive on both ends.  And then, the High-pass Negative to the Low-pass Negative on each end.

If you were biwiring a speaker and wanted to single wire to the amp (like most folks), you would:

>On the amp side of the cable only, connect the High-pass Positive to the Low-pass Positive then the High-pass Negative to the Low-pass Negative.

BTW, where did you buy your cable?
