I´m interested in some graphs that illustrates the distorsion on
some drivers like;
2123
2012
2202
2206
2226
2242
2035
On the PDF´s in the JBL website there is some graphs, but i cant read out
the procentage distorsion values...
What JBL driver would have the lowest distorsion in the range 200hz - 3500hz ? NOT horn driver.
heeeelp....
It would probably be a good idea to tell us what you are trying to do. I would not use any of the listed drivers up that high. If you look at the 2012 spec sheet it tells you in the text what the distortion levels are and only over the target range of 100-1600 Hz. Have you looked at 2118's????

But there is no information about distorsion on the 2118 PDF
What's Up Niklas ?
Do your S9500(s) still not go loud enough ?
If that's the case, you might need to consider horn-loaded midrange as your next best option.
Hi Niklas,
What is your goal? It seems you want to put together a speaker system with a frequency response of DC to Light that can produce 140dB with less than 1% distortion.
Did I get the specifications about right?
Are you concerned about phase distortion, time alignment, group delay, or stereo imaging?

No, I´m asking for a friend. midrange between 200hz - 3500hz !
With ultra-low distortion ! no horn, just regular driver.
WITH ULTRA LOW DISTORTION !!!
i hatedistortion
I will tell you all when I will replace the S9500 with something better
But I can´t see how there can be anything better though !
Im sorry to tell you this..Nick..But threres no sutch thing as ultra low distortion in a single speaker. Its always tied to some thing else in its design. Semetricle field, shorting rings. surround types. under hung, over hung. mass rings. Thiel Small peremiters. cone materials. And how good you measure them on a givein day.
Why don't you go the clasic 4 way. But only in the sense of using a dedicated midrange driver over a narrow range. Either a 2122/2123/2012 will kick butt. Especially when used over a narrow range say 300-1.2-1.5K like the classic 4344/4344Mark 2 and 4348. All I can tell you is the vocals and clarity and instrument definition you can get out of a 2122/2123 operating this way is really stellar. Have no idea what the distortion numbers are but from the way they sound it has to be pretty good.

What's the application (SR, HiFi, main/nearfield monitors, ...)? How were the desired crossover frequencies determined (and are they really "engraved in stone")? What are the requirements in terms of sensitivity, acoustical output, directivity etc? What transducers will be used below and above in frequency?
If he must take the cone up to 3500 Hz, we're talking small transducers (unless it's SR on the cheap, but you said "ultra low distorsion"...). Furthermore, I suspect he can forget one of [200 Hz, 3500 Hz, low dist, JBL]...
HIFI -purpose 3-way loudspeakers
let´s say 300hz to 3500hz and under 1% distortion @ 100db
5mm of xmax minimum
this one from Seas does not computeNot so smooth response,
and the distortion is to high.
Maybe some of the drivers used in JBL monitors would work?
Some of you must agree it would be very very interesting to find a driver
that can be this great as under 1% @ 300hz to 3500hz @ 100db
5" - 8" driver perhaps...
The Excel series was my first thought, too. That seems to be one very fine driver, but of course it would be nice to see waterfall plots as well. Maybe 'Klang und Ton' have tested this category of drivers in the last couple of years?
Well, from those graphs ,, I see we have two different interpretations of what is a smooth FR or "acceptable distortion levels".this one from Seas does not compute Not so smooth response,
and the distortion is to high.
Looks decent enough to me - how does it sound ?
Anyone here ever heard this transducer ?
I´m interested to know if JBL has any better driver than the Seas driver !
The C500G cone midrange seems to work very well in the LSR32 from 250 Hz to 2500. It's now on the transducer list for $159 a pop.
