Jantzen Wax Coil or Mundorf M-Coil CFC


Hi Everyone,

Need to build a new crossover for my Tannoy Monitor Red. My first choice for inductor is Mundorf Copper Air , M-Coil CFC. But it don't have the value I need and so I have to ask Mundorf to custom made it for a price. Then I found the Jantzen Copper Wax Coil, which looks fancy and cheaper. However, Can't find any review online. 

I am wondering if anyone has experience with these coil and which is better? 

thanks

Better in every way. 

Iron cores should never be used in any speakers you care to keep around.

 

The foils are better than the litz in resolution, dynamics, speed, clarity, timbre to name just a few things.  

@alexberger if it's the for the mids, I'd go 12 gauge, the larger coil just sounds better in every way, at least it did in my speaker setup.  

ADD:
The main difference between the two is in their Timbre. Jantzen wax sounds rich and velvety, perfect for jazz, acoustic and classical. The Mundorf sounds drier and faster in comparison, good for EDM/trance.
Both are copper foils, the housing makes a pretty dramatic difference in the sound both produce.
If money is not an issue, Duelund Cast is the best inductor on the market.

Inductors make a MASSIVE difference in sound quality, as much as capacitors.
The Jantzen Wax Coils are dead silent and have a black background, and have amazing dynamics. Get the 12 gauge version...

I know this post is 5 years old, but I had to correct the record. And yes, the wax coils are a serious upgrade over the mundorf plastic coils. The plastic coils are noisy, they have a harsh ringing in comparison to the paper wax housing. 

By plastic, I mean the Polypropylene used to insulate the foil capacitors. 

Both the Mundorf and Jantzen wax are amazing inductors...but for me, that paper housing has a more vintage/analogue sound, and the background is jet black. 

You will not go wrong with either to be honest......Mundorf also makes a papper coil capacitor, that is encased in paper and a proprietary resin. 

On my next speaker project, I will be getting some Duelund inductors, and all Duelund foil capacitors to do my crossover. 

 

Correction, The polypropylene is used in the MCoil inductors. 

The VCoil are the paper and resin inductors. 

I have only used the MCoil inductors, and that is they have a plastic housing.

The VCoil foil inductors should be a very good competitor to the Jantzen wax though. 

@gererick Honestly, I can only go by what others have said, they are supposed to be the best inductors on the market. I have extensive experience with Duelund capacitors and they are worth every penny.  Their performance for me has been phenomenal. 

I will be getting some Magnepan 20.7s at some point this coming year, and of course I'll leave some impressions...till then it's fingers crossed.

12 gauge all the way. I have tried 16 and 12 gauge, and the 12 sounded better in every possible way. The difference in cost is nothing for an $18k speaker :)

I think anything over 12 gauge might be overkill, but then again I have seen others claim otherwise. Mundorf has a 70mm wide inductor, comes out as 10 gauge which might be a good option. 

Jantzen 10 gauges are thicker foils, which I would stay away from. 

 

You have some very nice speakers, hopefully I get to listen to pair one of these days. 

 

I would definitely take you up on that offer, but I am on the other side of the country.... Los Angeles. 

I hope you can get your crossover figured out 🙏

Those speakers deserve a good one.  

You should be fine with the Mundorf honestly.

If the wait was say a month, that would be a different thing, but a year is unreasonable.

The 70mm foil should be perfect for your application, just make sure to also upgrade the wiring on the inside of the speakers.

My USB and XLR cables are DIY copper foil. 

Speaker cables are 12 gauge Neotech Solid OCC Copper DIY

Internal cables, including crossover are 14 Gauge Neotech Solid OCC copper

 

Once you build your crossover, just try out a few different ones, see what sounds best in your application. Every speaker is different. 

 

 

@grannyring My dac doesn’t use the Power and Ground connectors.

It was hard at first, but I have gotten very good at it :) The trick is in the fold at the very ends.   

I use 16 gauge Mundorf foil for my cables. 17mm wide.

And yes, they sound incredible.
