yes is for one only .... like I haved write ..... but in CAD$ = +/- $450. US
For the Dipole 140-15DAM model .... less for the no amorphus model
If your system is not Hi-End you will , probabelly , not earn too much difference betwen many ribbons .
It's more that just a tweeter , ..... he is a tweeter + supertweeter ( go up 80Khz )
It's less expensive that the Townshend supertweeter only

Legis,
This is so interesting to me! Would you happen to have, or point me in the right direction to, similar data for a 45 SET tube? I'm designing an active 4-way with the goal of driving the tweeters and midranges with either 45 or 2A3. I had seen comments related to what the graphs depict, but never saw actual data.
It depends on the circuit and whether GNFB is used or not, but basically the shown distortion spectrum is more or less applicable to all non-GNFB SET amplifiers.
I have now listened to to 5µm ribbons in Neo Pro 5i for over a week.
Rotary cutter + ruler is good for cutting straight ribbons over for ex. wooden platform. Highly recommended. 5µm ribbon is sensitive stuff, rotary cutter does not try to tear it like a razor did.
5µm gave ~2dB more sensitivity between 10-20kHz. Measured freq response otherwise is quite close to original, both are straight aluminum ribbons so the biggest difference comes from the weight related things. Thinner ribbons sounds more airies and "massless", better to my ears. I'm temped to try 2,5µm riboon at some point. 😉
I also listened to the ribbons with and without the impedance matching transformer. For some reason I preferred the transformer coupling to resistor coupling and also to direct/resistorless coupling. I plan to test it more and add another step-down transformer alternative to the mix. I also have a 4:1/8:1 toroidal transformer which I intend to try. It has normal silicon steel core while the Neo Pro 5i transformer has ferrite core (which are used usually in RF applications due to core material's very high bandwidth).

2 pairs of viawaves are arriving next week. might have to part with one pair but the other is going into a TL build with the alpair 12p. Can't wait to hear the result.

Hi,
Interressant testimonial 🙂.
What sort of amp have you on it ? Tubes , SET ?
How do you find the sound in relation to a magneplanar type of sound à la Magneplanar ?
I have both transistor and SET amps. The transistor amp is more for everyday listeining, SET is for candy-day.
I find Maggies' top end good, but I think they might not be made of the thinnest aluminum foils around. Propably something heavier to make the longer ribbon more robust. Everything else about Maggies sound I do not really like (or more accurately do not prefer in comparison to others). They are quite lame, sluggish, anti-dynamic, not very "present" and with no real "snap" to speak of like electrostatic speakers and horns have. Not my cup of tea, I like a presentation that has more life-like dynamics and transients.

^What I wrote came out little too negative sounding after seconds read. Maggies aren't bad speakers. I have to add that Maggies do have quite good tonality, acoustic instruments sound good to my ears.
Quick update related to this:

Since i extensively test DAC on the tweeters (RAAL 210-10D) and i see the very obvious impact DAC's can have on these tweeters performance... I can say without a doubt: if you choose these extremely efficient and details-enhancers 210-10D, don't forget to put serious effort on the DAC matching.
These drivers don't forgive bad DAC, like, at all.
But when you match it with something good, it's as close as you can get to audio nirvana. Assuming you carefully EQ'd it of course... (don't even bother using that one if you're using passive config without EQ).

follow-up...
Combo with RAAL 210-10D and Weiss DAC1 mk3 is the most impressive high frequencies i ever heard in my life.
Those 210-10D have mandatory needs: EQing and a good DAC.
I'm still shocked on how the DAC's quality makes such a huge difference on the tweeters and especially this model.

Just received two pairs of viawaves. Very solidly made, lovely looking things.
Smaller than I imagined.. the Alpair 12pw looks huge in comparison

I would really like to try those ribbons Bill, where did you get them from and how much are they?
Those look rather similar to a range of ribbon tweets of different makes distributed by folks like CSS / Parts Express.
PM'd
@&"! U.K. Customs look to have run a battery across a couple 🙁 but luckily they came with spare ribbons
Hope they work well with the alpairs, itching to do this build but another to finish first

I have a pair of Viawaves as well. Nice sounding tweeter! Would be perfect above a small mid such as the 10F.
No, they met a cop in Carolina State USA !
Where have you been sourcing those beauty ?

Also nice that the waveguide makes it easy for time aligning the drivers. If they are as good as everyone says I'll probably just use these tweets from now on.

The H-100 is also my best by far; but
The H-100 is also my best by far, but it is no longer available. I do own a pair of diy speakers which include two H-100 each, but I would like to build another pair for my sound room. Have you listened to the Fostex T900A or T925A? They are smaller, and although Fostex claims 38khz and 40khz respectively, their slopes are steeper past the 20khz mark. I would buy other H-100 if they were not used, for I do not want to buy ones which have been abused or played with the wrong crossovers. They cannot be easily rebuilt if at all.
Thanks for reading my reply and get back to me if you have found any solution. I've been an audiophile for over 45 years and heard an endless array of speakers. Every year I attend the CES in Vegas and do so only to hear the supposedly best audiophile speakers in the world. I've listened to speakers estimated at over $190,000. a pair, and none come even close to mine in any respect. I think that the H-100 are simply the best tweeters period. I've listened to $74,000. a pair diamond tweeters and was not impressed even before asking for the price. The H-100 blows then away in clarity detail, smoothness, sound stage...
