Hi,
I am not an expert but it doesnt look like an iwata to me. Looks like a bruce edgar mid horn.
Other people that have something like this using a Fostex FE126 commented was great improvement, with better directivity.

Other people prefer CDs for mids.

your probably right, I have ZERO experience with horns, except a small bullet tweeter I used for my friends PA sat system.
Anyway, I am interested to learn more about this speaker.
If I change apartment for a house (perhaps very soon) I would like something like this for my biggest room....
But that is a far far future, I ave to finish current project first

I am a newbie with horns also, just researching for a new speaker proyect like you, using horns.
Looks to me that horn doesnt go low enough, you still need a bin bass to go down to 40hz.
So probably you need a several ways speaker. Good or bad depending in your goals.

What are you thinking on?

looks cool
I have recently built these
100hz should be in reach
needs bass bins yes
but thats part of the whole setup
and just one way to build effective speakers

tinitus: any link to them? or description?

charly:
I am thinking about folded sub which could be placed under the mid bass, then either traxtrix on top or bi-radial or whatever would match with them.
I had a look on the Wicked One from Decware. What I like is the size of it, what I don't like is 4 woofers... it can get expensive.
I already sketched up the Iwata midbass to get me a sense of size. Well, compared to Onken or even petite onken, the Iwatas are PETITER

will see if I can work out some documentation describing them
they are calculated for a cheap 12" Fane(12-300)

should I build bass module/bins for them, I would consider slot load style bandpass
I designed it for bass guitar, but experience from previous project tought me to build two, just in case ....
might start experimental design where slot shape and size can be changed
but I need drivers, and they cost money

but since this kind of midbass horn doesn't need any highpass crossover, I guess a simpler(and more predictable) vented BR bass bin with active filter would do

for the top/tweeter, a unity horn design is tempting to try

hey, just for you I connected one of them to my 'hifi' stereo
nah, joking... I have postponed it for too long

wow ... sounds like they really have the potential to become good musical 'hifi' speakers
