Wouter had een tijdje terug ook een site gepost met scan speak drivers.

Deze bedoel je http://www.audiocomponents.nl/scan-spea ... views.html ?
Hier stonden ook mooie metingen op, de site is alleen (tijdelijk?) down: http://www.audioheuristics.org/

Interessante site met metingen van diverse drivers per categorie en de vergelijking met de fabrikantgegevens.

Die kende ik al, goede site! Met Google translate kom je een eind. Wel ff een account aanmaken. Ik heb daar de data van de Fountek Neo cD3.0 vandaan gehaald.

Ff een bumpje: HifiCompass. Volgens mij kijkt Vladimir hier zelf op als hij wat aan het speakers bouwen is.

Hier zijn ook wat driver metingen te vinden: http://www.audioexcite.com/
En hier een aantal metingen gratis te zien uit Voice Coil via de tag "test bench": https://www.audioxpress.com/tags/Test-Bench
En deze kent iedereen al wel maar zal hem hier toch nog plaatsen, staan bij veel ontwerpen ook metingen en verder nog een paar onder "recent updates": http://www.troelsgravesen.dk/Diy_Loudsp ... ojects.htm

Ziet er redelijk recent en netjes uit. Ik had hem nog niet eerder gezien. Niet echt metingen maar kopietjes uit de datasheets.

Je kan dan weer wel zoeken op parameters.

Helaas bestaat de site van John Krutke, Zaphaudio niet meer: https://www.facebook.com/groups/DIYLoud ... 440808559/

Nou ik kan er nog prima op komen.
Het werkt alleen niet meer voor mensen in de EU (ivm bepaalde regeltjes enzo) dat is al jaren , dus gewoon even een VPN of online proxy gebruiken.

Ik dacht dat Krutke schreef dat hij van de audiohobby is overgestapt naar de racehobby. Maar VPN helpt inderdaad.

Zaph Audio Post Mortem

Hey guys, just a final update to this web site.

In case it's not obvious, I am no longer active in the DIY speaker building / testing / design hobby. There's no real solid reason why other than my participation has run its course, I've lost interest and moved on to other things. This web site remains, mostly as a DIY design guide. Heck someday I may get back into it and need my own web site to remember some things.

The fact that I started selling my own speaker through Madisound has nothing to do with it. I've heard it said before that as soon as you go into business for yourself, it stops being fun. But that's not the case for me.

Something that hasn't faded is my love of music. In fact, since exiting the speaker hobby, I find that I like listening to music even more. When you remove "critical listening and evaluation" from the listening equation, all that's left is to enjoy the music. It's not really much fun being a "chin stroking audiophile". I've found that for me, listening to music while trying to find flaws in a speaker design just sucks the enjoyment out of it.

I've sold my old big, heavy and hot amplifier and I'm now a big fan of digital tripath amps. There was no real reason for me to keep an old fashioned 60 lb monster around when I only really need a couple watts. I should have done that many years ago.

I do still work on an occasion audio project or test an occasional driver here or there, but my days of frequent posts to this website are unfortunately over for now. It seemed like I had a lot more time back then. There are many more things in my life fighting for my time these days.

What would I have done differently?

When I look back on the things in my speaker building hobby that I might have done differently, there's only a couple things that I would have changed. It's the music that I sometimes listened to that I really didn't like, as part of speaker evaluation. Just because someone said an artist's release is a good recording is not a reason to run out, buy it and force yourself to listen to it. There's a certain amount of snobbish attitude exhibited by fans of classical and jazz music, suggesting that this is the only music to judge speakers with. I think I even agreed with the music snobs at some point, but I've come to realize how wrong that is. Just listen to what you enjoy.

The other thing I would have changed is that I would have protected myself more from MDF dust while building speakers. People, that shit is NASTY and I had lung damage from it for a while. Never work in a confined space without airflow, and always wear a mask. (and ear and eye protection for that matter)

I would have kept my hobby more secret among friends and coworkers. Because every damn time someone finds out I used to be a speaker designer, the next question is "Uh... Can you help me hook up my home theater?" or "Uh... what's the best subwoofer I can get for $99?" and my answer of course is for that price you get what I call a "fart box".

What do I miss?

I miss interacting with some of the awesome speaker designers I used to chat with on the forums. I have no idea if any of these guys are even still around, but Dennis Murphy, Jeff Bagby, Mark K the other John K whose last name I couldn't hope to spell, Jon Marsh over at HT Guide and many others. All geniuses and it was great to chat on the forums overs the years back in those days.

I haven't been on a speaker related forum in so many years and it would be weird to stick my head in there at this point. But know that I do miss all my old chat buddies.

What don't I miss?

I kind of got tired of internet participation in this hobby. It's such a fringe hobby, yet I found it strange that because of my tests and projects, I gained so many fans but that came with a good number of haters too. A few "competing designers" really started to hate me. And even though I stopped doing it the last few years of driver tests, sometimes I didn't like posting bad results. Somewhere every driver is someone's baby or someone's favorite.

10 year anniversary of the ZA14W08 woofer

Wow, who would have thought I would still be selling those after all these years. Thankfully the price only went up a little and consistency has been good. I still test every batch. Interesting story, back in 2009 or 10, I recall someone saying "well look at that ZA5.5TT speaker - Zaph really wants to sell a lot of those woofers!" The funny thing though is that design came first and it was the reason the ZA14W08 was born. I became a serious believer in what the MMTMM format had to to offer and I wanted to do one the best I could, but I just couldn't bring myself to buy that many Seas Excel W15 drivers.

The idea at the time was to build enough for a few of my designs, the TT's and some extras, then hope I can sell the rest and break even. I ordered the bare minimum batch size at the time, 250 drivers. I asked my buds at Madisound if they were interested and they were, more so if I posted a few designs. I ended up posting the whole ZA5 "family" giving people a lot of options, and I use every one of those myself. In almost no time Madisound calls me up and says "we're going to need more." And they kept selling since.

So, I've been selling a driver for 10 years, roughly 6000 of them sold, but make no mistake - I still have the highest respect for the serious quality names of Seas and ScanSpeak. If I had a little more money at the time, my ZA5.5TT would have been made of Seas Excel or ScanSpeak Revelators, and the ZA14W08 would not be around. Seas and ScanSpeak always have been and still are the best.

So what HAVE I been up to?

I've been racing motorcycles for 6 years. At the club level, nothing too serious, not about to put Valentino Rossi out of business, hahah. I've recently retired from that due to old age, and I think I've reached the maximum number of broken bones a person should receive over their racing career. I currently have 3 titanium plates and 50 screws holding me together. I wouldn't say it's been an easy... or cheap 6 years, but I wouldn't trade it for anything. Made a lot of friends at the race track and have a lot of incredible memories. These days I wrench on road motorcycles and have a garage full of them. I ride some minis on a kart track and ride a BMW adventure bike on the road often.

But... we miss your driver tests!

See Hificompass.com. Very cool set of testing and very thorough. He is definitely carrying the torch for driver measurements.

Jaartje later
Achja speakermetingen de akoestische omgeving en luisterpositie maakt het allemaal toch weer heel anders.
Misschien moet de standaard afstand van mic en speaker worden veranderd naar bijvoorbeel 2,5 of 3 meter.

[WrineX]

nouja ligt er aan welke drivers tweeter gaat prima op 1 meter met gating. woofers. tja. dat is een dingetje
