The current version of the JX92 is shielded.

Did you hear them before you bought them?
The mids are what they do best, but after everyone being used to 4" bass from FE103 class drivers they do astounding bass, and from the FR curves you expect them to be noticiably rolled off at the top... that they don't meet these preconceived expectations is why pople's 1st comments are about the ends of the spectrum.

I heard a number of implementations at the last RAWfest... the line arrays with these (given a room that was WAY to small, and an unoptimized Dan Wiggens style XO) they were not put in the best light, but a simple 2-way was much better, and the weird ML-QW box with a single WR125 -- althou still not optimum (you needed to sit on a very HIGH chair) were quite stunning. I really want to hear them in a bipole based on an ML-TL design Tim worked up usuing Augspurger's SW. Tim did a MMT with a Foster dome, i'm going to commit heresy and try them with a waveguide loaded ApexJr 50 cent tweeter (and then maybe the $11 gold version by Audax)

I forgot to say, if it were my project, I'd go high efficiency and use a Radian 12 coaxial. This is a driver actually used in soundstage mixing systems. I don't know if that would meet your budget or not.

BTW, I like ribbons for music, but they wouldn't be really my first choice for HT, though they work OK. I tried them for this and they ultimately got relocated. My AC ribbons have superior detail resolution, but a slight shimmery coloration and compressed sound, compared to compression horns. I prefer them at modest SPL levels.

Very good point. Maybe I should tailor the response a little to boost 200-5000.
I’ve googled a bit on this, but haven’t found anything for a while – do you have a link?

Morbo
Thanks (I’ve seen that)

Greg B
How much is a Radian 12 coaxial, if it’s 12 inch it would be too big fir this app.
Compression would not be good for music, but ok IMO for HT.

Dave
“The mids are what they do best” – great, thanks!
(As long as they’re about as good as the Jordan 92).

BTW, what’s Augspurger's SW

Is there a site (Adire??) that has more info on the CSS WR125, eg cone material . .

Rick - the cone material is paper, surround is rubber, phase plug is copper. A very attractive driver IMO. Here's more info;

One of the 2 available modelers for TLines... I've seen it and i think anyone looking for such software would be better off getting a copy of MathCad & using Martin's model.

Hi Rick

You may want to check out the Radian 508/2B

Works well in sealed box too.

Thanks! I hadn’t seen the PDF link (where was it?)
So paper cone can equal metal?

Dave
I tried to get/ install a copy of MathCad a few months ago, but IIRC it wouldn’t install on Win XP.

mcp
The Radian looks very good, but not for my app. But I let a friend know, thanks.

Variac
And very good $ too.
