Midrange dome drivers banned ?

Thank you for the link.

I could download the owner's manual for ATALANTE 3 and found the cabinet is rear ported (bass reflex) design with the port cap for making it into quasi(?) sealed cabinet if needed. I assume ATALANTE 5 would be also ported (bass reflex) cabinet; I will soon confirm it by contacting with the Revival Audio people. I believe it would be rather easy to make them into "perfectly sealed cabinets" by simple DIY with removable tight-(screwed?)-gasket-thick-lid, if we would like.
The Atalante 5 has 2 rear ports. They give you the foam plugs.
 
Thanks for the info.

Yes, I found the backside photo here. Yesterday I started e-mail communication with people at Revival Audio inquiring various aspects including technical and measurement data of ATALANTE 5 and its SP drivers.

Wharfedale EVO series. I had the 4.4 towers for about a month, and hadn't found the dome to be clearly superior to that of cone midranges at a similar price point in terms of resolution, imaging, or soundstage. We would expect the dome to have great omnidirectional dispersion as its main selling point, but I found that hadn't been the case, particularly as a system. The dispersion of their AMT is quite a bit narrower; that's what I had noticed more. One would think more people would be using domes, if they had clear advantages at a certain price point. I've been doing more reading about the BMR that the Philharmonic bookshelf speakers have. All things being equal, I would have got Revel F36s instead at the $2000 price point due to improved bass. I would imagine the midrange quality would be more or less comparable between the two. I had gotten rid of the EVOs because of their mushy bass when using them with classic rock music. It hadn't been the midrange.

I'm not sure whether a dome, cone, or circular flat-panel driver, will have significantly different off-axis dispersion patterns. Does anyone have any sort of measurements and/or simulations that might shed some light on this particular characteristic?

What domes have is insanely high radiating area per diameter compared to a cone, limited by their way worse LF extension (except for the unicorn ATC dome, which I'm convinced can only do it because a.) it's an underhung coil and b.) it's got a dual suspension to keep it more linear with more excursion, and is still only good to about 400hz).
 
Correct, cones are often less stiff and thus the active radiating area becomes smaller at higher frequencies making the directivity rise less sharply. Also an ideally stiff flat membrane beams less at typical relevant audio angles than an ideally stiff dome or convex shape while an inverted dome or concave shape even less due to the differences in the path lengths from the different points on the membrane.

I would find out which three way speakers have domes, then look at off axis frequency response curves for a number of products. The one that has a bigger sag in the midrange at 30 degrees, has worse off axis response. The peculiar part for me, was, I had happened to have gone from what looks like largely the same AMT tweeter from one three way product to the next. The difference was, the Wharfedale had it crossed over at 5 kHz, and the Martin Logan, 2.2 kHz. So, I had made things worse for myself in some ways.

There's a HiVi Swan three way kit on Amazon for $300, that would probably be the cheapest way to find out what the dome sounds like.

It's a little annoying that two different topics are about the basically same subject.

Yes, the directivity of a dome is different than from a cone speaker.
This has been discussed in the two books I keep on bringing up by Eargle and Borwick.
Typically in a 3-way system, the directivity is very low, so a much wider dispersion.

As for why and how there is a lack of midrange domes;
I am basically gonna repeat what I said in the other topic about cone tweeters.
In this case midrange domes only full-full a small niche.

They made a lot of sense in the 70s/80s, when most tweeters couldn't be used below 2,5-3kHz as well as in combination with a 10-12 inch woofer.

These days the majority of tweeters, even without a waveguide, have no issue at crossing around 2kHz.
Also 5 inch mid-woofers perform an awful lot better. (since distortion always seems THE selling point no matter what)
While the crossover is much more simple and cheaper, compared to a 3-way system

Do Revival Audio own a Kippel NFS? The Atalante 5 looks promising and have been getting some good comment by people who have listened to them.
 
Let us know if thier available in the US. Thanks!!
Contact Tone imports and they will get you in touch with the US dealer.

I'm afraid this will be a situation where if I have to ask the price I can't afford it.
 
Bliesma makes some mids with 4 different material options.
Some manufacturers are also using really small diameter "cone" midrange eg monitor audio .

It looks like you get to listen to midrange dome break-up resonance with that speaker?
 
Can you try to translate it to english?

Edit: it works in chrome

Yes, "into English" is quite OK with my Goggle Chrome!
