Peter,
Thank you for the follow up on the questions I asked. I like your explanations but will also have to think about them more to completely understand them. I think any other information you could add to this discussion can go to a PM where it won't interfere with the conversation here. I am aware of the problems of adhesive types and also materials used for surrounds so am very interested in any additional information you can provide.

It's a pretty long listhere are a few exceptional recordings I go to to evaluate the music playback in the big system - surely none are "perfect" that's why I find it hard to say absolutes like never or always when referring to playback - all recordings are flawed as far as I can tell so there is no "absolute"
try these
Eiji Oue - Rachmaninoff: Symphonic Dances RR LP
Audio Sympony Check up your donds RCA LP
Fennell Trttico RR CD
T Houston Pressure Cooker Sheffield D to disk
Sheffield "track" record LP & CD
Tor Dietrichdon Global Village CD
Bernie Krause Citadels of Mystery MF LP
John Klemmer Touch MF LP
Ala Carte Brass & Percussion Wildchild CD
Sheffield Track Record LP
Rusted Root - When I awoke CD
Pretenders Isle of View CD
Arch Choir Mapleshade CD
many many more LOL
POOH,
Just to clarify, is that last one (Mapleshade CD) titled "Walk with Me" by the ARC Gospel Choir. If so, that particular CD is one that I've written about several times over the years as an excellent evaluation tool.
Best Regards,

carnegie - Belefonte also comes to mind -
Harry Belafonte - Mama Look A Boo Boo (Carnegie Hall) - YouTube

I remember listening to an excrutiating vinyl playback of the Belafonte one at a hifi club meeting- it downright amazes me how people can listen to dreadful levels of distortion, and excuse it, because it's say, LP ...
The Odetta is good, because it's "bad" - Vanguard recording, the levels are incredibly low, maximum volume is no better than normal TV sound; but all the acoustic clues are there to hear if a system is up to scratch ...

Ha, yes - the worst case i heard belefonte album (it was my pressing) was over at a fellows house where he had a big Walker table multi-thousand dollar cartridge and head amp NO preamp just nude vishay resistors he plugged in to attenuate the signal into some massive Krell class a mono amps driving B&w Natulis 801's - I almost cried from the pain - from like 3k up it was actual torture

Good Grief! That sounds like it must have been dreadful!

There are those that just throw money at the system and they usually sound dreadful. Nude Vishays. I remember makinga new power amp PCB. I used Vishay but I took most of them out as I did not like the sound result through my Quad ELS57. I found Holcos gave a preferable sound. So naked VIshay or anything else forget it. The great thing about DIYers especially at the top of the technical scale is they make usually what sounds best for them at a reasonable cost, that they will sustain, as nothing is for free.
I am impressed that SEAS have made a Be tweeter SEAS T29 001 but it cannot be worth $550 when $50 buys something almost as good. Better to spend the money on a decent amp and keep the cheap tweeter. What would you do if hip and other replacement jionts used more and more specialist materials. They could start charging say $100000 for a hip joint, then the surgeon would say he wants some of those dollars. Madness.
If the new relatively simple state of the art parts were realistically priced the market would take off. The expensive rubbish keeps the DIY market down when you can buy Behringer and other makes that save the DIY effort.
Boldname,
As someone working on a Be dome tweeter I can tell you that the cost of the material to make those dome tweeters, the Be, is $35.00 each, almost the retail cost of those other dome tweeters alone, so there is no way you will ever see a $50.00 dome with a Be diaphragm. Does that mean the tweeter has to cost 11x's the price of the other unit no, but you would have to look at the multiplication factor they use to price their products. What you don't realize it that most of those $50.00 soft dome tweeters probably have about $5.00 worth of parts in them, the marketing and design is what you are paying for and some profit to keep the company in business.

Hi,Thanks for your useful remark.
My perception is the multiplier is a tryon set much too high. If they were $250 each then they might stand a chance. The reviews do not seem to set them apart from mainstream domes. At the money a smaller RAAL ribbon is looking generally better and more exiting.
Boldname,
I understand what you are saying and sometimes when I see a ribbon tweeter going for $1,5000 I have to shake my head. The markups are just so arbitrarily high some of it has to do with perceived value, the higher the cost supposedly the higher the quality. It is a struggle to find the correct balance between a retail price and positioning in the market.

Once the market gets back to precrash days but with less rapid growth, it may be that Be and Neodymium etc will settle at a better price with the BRICS countries not so massively swallowing up rare earths and copper.
It all runs a fairly predictable cycle does it not, along with the markets and sentiment. Dave Ralph, John Kreutke and others helped many start DIY without too much risk.
The Radian 2" 760NEOPB looks too good to be true - flat from 200 - 20K Hz in the plot below. Can this be right? This is not even the Be version.
