Yamaha NS-1000X

Last year I'd noticed a couple of pairs of Yamaha speakers listed on eBay as NS-1000XW. I don't know how these compare to your pair in but both were listed as supposedly working and in good condition without tears, dents etc. One pair sold for a little over $1,600.00 and the other pair sold for $2,164.00.

I hope that helps.

I have no affiliations with either transaction.
 
Needed a few days to myself so I've been away, sorry. In those days I did some serious research to clarify what I understood about them.

Firstly, thank you to those sending me your wishes and prayers; they are working. I'm feeling better with each day, which is very surprising given my diagnosis.

I've decided against selling them. Frankly, you never know what the future holds. I worked too hard to acquire these. Besides, my only motivation for selling them was so that my parents wouldn't have to deal with them in the future. But, I need their help even if I sell them now.

I'm going to remake my assertion that they share more technology with the NS-2000's than they do with the NS-1000M. Tinkerbelle, the valuations that you found should be right in range. The only difference between the two models is the finish color. Worth noting is that the blonde finish (1000xw) had a higher msrp than the black (1000x) though.
 
Yes, I had read, too, that the finish was a difference between them. I'll be keeping a watch out for them just because they are so relatively scarce and have a good reputation.

It's good and positive that you're keeping them. May you have many long years to enjoy them.
 
At this point, rather than let this thread leave a future NS-1000x researcher hanging, I'm going to try to convey as much of what I've found as possible. As I said, they are closer to the NS-2000's than the NS-1000M's, so I'm going to compare and contrast them.

I think one of the reasons these speakers are so greatly misunderstood is that, AFAIK, they were not sold in the US. I cannot find any US marketing materials. I was able to find Japanese ones though:
http://www.niji.or.jp/home/k-nisi/ns-1000x.html
I've tried running that through multiple translators, and what this document is doing mostly is stating how the parts of the speaker are derived from the technology used in the NS-2000's.

The NS-1000X began manufacture in 1984, the NS-2000 in 1982, the NS-1000M in 1974.
The NS-1000XW is the same speaker as the NS-1000X but with a natural finish instead of painted black.

Cabinet:
  • The 2000 and 1000X both have thicker particle board.
  • The 2000 and 1000X both have rounded front baffles to minimize diffractions.
  • The 2000 and 1000X both have the drivers vertically aligned.
  • The 1000X has a "bi-cabinet" design with a woofer chamber integrated into the bracing.
  • There are no meaningful similarities between the 1000M and 1000X cabinets.

Drivers:
Woofer:
  • The 2000 and 1000X both have carbon fiber woofers with similar structure and manufacturing processes. The 1000M has a paper woofer.
  • The 2000 has a 33cm woofer, the 1000X has a 30cm woofer. The 1000M has a 30cm woofer.
  • The 2000 and 1000X both have OFC in the woofer voice coil.
  • The 2000 and 1000X both have stronger strontium magnets optimized with FEM
  • The 2000 and 1000X both have the same type of surround, I believe. The translation seems to flip flop on this depending on where I get it.
Midrange and Tweeter:
  • Part numbers for all models
    Tweeters: NS-1000M: JA-0513 NS-2000: JA-0526A NS-1000X: JA-0548
    Midranges: NS-1000M: JA-0801 NS-2000: JA-0802A NS-1000X: JA-0803
  • The 2000 and 1000X both have OFC wiring
  • The 2000 and 1000X both have stronger strontium magnets
  • The 1000X and 1000M have the same size magnets, the 2000 has larger magnets
  • The 2000 and 1000X both claim the manufacturing of the beryllium improved over time leading to better dispersion characteristics.
Crossover:
  • The 1000X and 1000M have the same crossover schematic, including component values
  • The 2000 and 1000X have components hard wired together and do not use PCB's.
  • The 2000 and 1000X have the physical spacing of inductors maximized to reduce interference.
  • The 2000 and 1000X have OFC wiring.
  • The 1000X has binding posts, the 1000M has spring clips.

Oddly, in my research, I found that most people consider the NS-1000XW to be smaller versions of the NS-2000, whereas most people consider the NS-1000X to be an updated version of the NS-1000M. While both are true to a degree, its nonetheless amazing what color can do to one's perception.

If anyone finds something to be incorrect, please reply or message me. I did amass this from a bunch of translated sites for the most part.

Thank you for the additional information. I have seen the Japanese website information and, in fact, if you go to the higher level on that site you can see all the various NS-xxxx series speakers and look at all their specs and features.

There are significant performance differences in the models; from the referenced site:
NS-2000: 28Hz ~ 20kHz, 6 Ohm, 250W rating, low resonant frequency 33Hz, 440w × 752d × 404h (mm), 47kg
NSX-10000: 35Hz ~ 20000Hz, 6 Ohm, 250W rating, low resonant frequency 35Hz, 450w × 752d × 410h (mm), 54kg
NS-1000X/XW: 39Hz ~ 20000Hz, 6 Ohm, 200W rating, low resonant frequency 39Hz, 427w × 695d × 335h (mm), 42kg
NS-1000M: 40Hz ~ 20kHz, 8 Ohm, 100W rating, low resonant frequency 40Hz, 375w × 675d × 326h (mm), 31kg

Lots of good information there and, again, I appreciate the time and effort you expended to provide the above additional comparison information.
 
As another cost data point for this thread a pair of NS-1000X in supposedly very good condition and with speaker stands just sold on eBay for $1,475.00.

No affiliations.

Never quit...you never know. I wish you all the best and prayers out to you and yours. I've got a friend who's battled AML for several years and just keeps refusing to give up. He will win the war.

Never underestimate the power of positive thought. Your parents can decide what is a burden for them and I would feel confident in saying that they'd tell you that NOTHING YOU DO would be burdensome.

I know it is a hell of alot easier to say than do, but when you're feeling bad, think of how many people are out there wishing you the best and know that you're in people's thoughts that don't even know you.
Then think about the feeling of those who do know you and how much they care.

I agree with your idea....keep them. Try to enjoy them because that is what you got them for.
Plusssss, music is therapeutic!!!!!!
 
Unfortunately there is no happy answer here. In short, I'm terminally ill.

No lie, it seems everyone on the internet thinks I'm lying. A little bit about me:
http://www.thebostonchannel.com/health/25994615/detail.html

I will do that for the website, I hadn't figured out how to do it without loosing the full res image, which I figured would be more important than the convenience.

Dear kgiessler: My apologies for anyone who thinks you are lying about your condition. Issues like forum rules and your audio choices pale in comparison to your ordeal that is beyond comprehension for most of us. The fact you are respectful to the forum and to your audio speaks volumes about your fortitude. I wish you the best of luck.

Congratulations on your choice to keep the NS-1000X. I own five pairs of NS-1000M's so your comments on the technology are particularly interesting. While the X is on my hunt list, they are very rare and I have not had the fortune of seeing or hearing a pair. I have owned two pairs of NS-500M's which have a Be tweeter, Ti mid, and a 12 in carbon woofer. I agree, the carbon woofer is a difference maker and IMO, makes bass a little harder and seemingly a little less well damped because the cone material is not as heavy. The 500M on first impression seems to have more accessible bass than the 1000M but that is because I think the carbon woofer is more efficient and easier to excite.

I also found that the 1000M is much more intolerant of poor performing amps such that only the fastest and most powerful amps can take advantage of the 1000M's transparency. And wow, can they perform. I'm running Kenwood L-09M monoblocks with the 1000M and this is the best solid state combination I have tried to date. As you noted, the 1000X is closer to other carbon woofer models like the 500M so I expect the 1000X to be similarly more tolerant of different amps.
 
"The 1000X and 1000M have the same crossover schematic, including component values"

Not actually true. Though oddly, not altogether wrong either.

Inductor 'L3' in the Yamaha NS-1000M service manual is stated as being 2mH, while the NS-1000X (L2 in that service manual) is stated as being 2.3mH. However, I've taken apart NS-1000M crossovers and have some right here infront of me and 'L3' is stamped on the ferrite bobbin as being 2.3mH. Maybe Yamaha altered it at some point during the production run.

This is an old thread, however I am looking at some NS-1000X which need new tweeters but they are very hard to come by

I am contemplating putting in a set of the, quite easy to find, NS-1000M tweeters i.e. use the JA-0513 instead of the JA-0548

You said "1000X and 1000M have the same crossover schematic, including component values"

So - putting a 1000M tweeter into a 1000X should work ok?

Not ideal, I know... but would appreciate any thoughts
 
@gilbert151

The member you quoted and asked a question to posted that 13yr's ago and hasn't posted or been seen since.

I see you just joined so welcome aboard and here's hoping you enjoy your stay here.

This section of AK is for asking about value, what are these worth etc

You would be better served creating your own new thread in the proper section "Speakers" and ask your question there were you will definitely see more replies, suggestions etc
