The advantages of the Mangers are their wide bandwidth (much wider than any other fullrange driver) and that they can do quite some SPLs. The Jordans however seem to have a flatter requency response than the Mangers (and also very low THD according to a recent lab report from a German mag).

I listen to my Mangers also nearfield because my listening room is quite reverberant (TECHNICALLY speaking it wouldn't be a problem to improve the room acoustics).
IMO it doesn't make a difference how orchestra and the like are "displayed" wheter you listen at 1 m or 1.8 m as long as the distance ratios are kept the same (apart from the changed ratio of direct/reflected sound which is depending on hte room).

I once had the idea for a speaker using a fullrange driver assisted by two woofers in D'Appolito arrangement, driven actively and using a special type of subtractive crossover. Such a speaker could be implemented not only with drivers like the Jordan but also with cheap ones (and still give some headroom due to the relief in the bass range). It would be suited for close-field AND mid-field listening.

Charles

Default Now hear this

(sorry for my english),

Put your stereo system in a church and then in a studio rec and after in
the middle of a desert and ........( the same triangle of course)
The result is totally different. The sound is a "space-time story" from
the speaker to you . Every single reflection modify your perception.
Wich is "correct" ? Again, what a speaker must to do and what
NOT to do? Monopole, bipole, dipole, omnidirectional, line source,etc?
Alls right? From LS3/5A "shoes-box" to amazing mega-speaker
of 2000 kg are they equally "corrects"?
One way, or two, .....10 ways!?? GULP!
What is the "criteria" ? higher the price, better the result?
IMO, this is a strange world where the listeners show do not understand difference from "bads" and "goods".
Excuse me for my cruel conclusion .
Hi alls.

Default nearfield

Hi Charles , im my opinion the woofer/FR would work splendidly as long as the Xo was ~ 100 Hz! thats a good idea. my subs are on either side of my chair and only the small sats are in my normal field of vision. I MUCH prefer seperate subs as it gives me freedom to place them anywhere

HI inertial from your question "what is correct? " I take it you dont hear much live acoustical jazz, blues or classical, and that is a shame cause that is what IS "correct" in its venue with its ambiance. Since i never listen to my music system inside a church, studio, or desert, i have not optimized my sys for those places . maybe u do, or maybe u just like to argue and be right I HAVE optimized my system to minimize the room effects so if music is recorded in any of those places it will sound like that place, not like my room . Thats what ambiance retrirval is all about! Most systems i hear are very poor at this .
What is my reference sound ? I had the same seat at the St Louis symphony for over 20 straight seasons and KNOW the sound of that venue! When i play thier recordings and it sounds like im sitting there listening, then I know that my sys is close to "CORRECT". Too bad u dont know what is correct and what is not Do all venues sound the same on ur sys?
Do all venues sound the same on my sys? ABSOLUTELY NOT! Each venue has its own characteristic sound , as it should. As i listen to YO YO MA's "Simply Baroque, the chello is mello, biting, singing, resonious, in an intimate space with the small orchestra behind YO YO. Sometimes they are the focus,and then they are, but thier position dosent shift and there is wonderfull space around them Carmina Burana is the polar opposite. Here we have a mamouth orchestra and percussion with a full childrens chorus , full male chorus, full womans chorus . simply immence sound in a huge space. The mucic fills a full 45 deg angle from my position, far outside he speakers. you can clearly hear the snare 40 feet away pin pointed in its own space. When all hell breaks loose in a forte` its immence as it should be and as i heard it live on a proper sys this music will grab ur soul and wring you out!!

welcome back Thor,
Maybe my english is incomprehensible , because you have misunderstand all my words!!
I'm sorry but mine questions was rhetorical ( and provocative, i admit)!!
I hope you have some sense of humor.
If your stereo give you the same sensation of the live performance
simply you have done a perfect work. Your research is terminated
and you enyoy listening "correct". Congratulations.
Best regards

Default lol inertial

YES, I have a sense of humour if i didnt my post would have more blunt One thing that dismayed me in ur post< and why I went on and on was this **"what
to do? Monopole, bipole, dipole, omnidirectional, line source,etc?
Alls right? From LS3/5A "shoes-box" to amazing mega-speaker
of 2000 kg are they equally "corrects"?

What is the "criteria" ? higher the price, better the result? "**
no the only criteria is how they sound
from this I thought that u were placeing more importance on the speaker than the sound. Above in my other post i give my preferences in speakers. Any of these are capable of what I want, except the EDGARHORN , as it dosent work nearfield, (Id LOVE to have it in a big room tho) but his slim line horn works closer and in smaller rooms, another fave of mine! So to recap , I listed 3 FR (which i would augment with stereo subs), 1 CO-AX , and 2 horns, both 4 ways when u use the sub so im not fixated LOL. Most importantly its the QUALITY of each of these implimentations, not the type! They are all superbe as themselves, some are just more superbe than the others, LOL, and range from 540$ a pair, all with subs to 10 thousand or so.

My own measurements put the Jordans and Mangers on a par
with respect to flatness and bandwidth. I think your preference
is more likely to be based on other characteristics and your
taste.

How far above 20 kHz did you measure, Mr. Pass ? The MSW goes up to 30 kHz which I can hardly believe the Jordan could do as well. But my imagination may be way off.

Regarding my preferences I can't comment on the performance of the Jordans sound-wise, since I haven't listen to one so far. Mangers are easier to get (though much more expensive) here.
Since you tested both: Wich one can generate more SPL before sounding muddy ? From the Vd point-of-view it should definitely be the Manger, but one never knows.

Charles
