Box speakers with ribbon tweeters

Correct me if I'm wrong, but just because they're in a frame like a dome tweeter, doesn't mean that the backs aren't open. I've seen some, and in some cases, the backs are open (come to think of it, I can't find one that isn't.

So it's just a matter of loading. You should probably load them with a (proportionately small) transmission line.

I mean, dome tweeters have the same problem. The diaphragm goes in and out, and from the other side, that still looks like in and out (or rather, out and in), so the air and sound still need someplace to go.

Yes, but I was under the impression that ribbons dispersed more sound to back than cones. That;s why I started this thread.

The EMITs used in the Infinity IRS were sealed. They were bipolar only by virtue of mounting a dozen of them in the rear. The ribbons in the Nola Grand Reference are likewise sealed and only radiate forwards.
