I don't know about that. I do get a pretty solid image. Maybe not as pinpoint as other speakers, but pretty good still.

Imaging has more to do with time alignment then dome vs. cone and to a lesser extent, intensity. The one thing domes do, is that they increase the area of the sweetspot. That is why most tweeters are domes. Producing high frequencies off axis is difficult, especially outside of 30 degrees. By using a dome, the window is widened. With a normal speaker you can clearly distinguish when you move a foot or two to oneside of the sweetspot. The image begins to collapse.

I agree. They typically sell for around $1,000 nowadays..give or take $300. I have the madacassar (spelling?) ebony finish. I have fallen in love with them. I'm using them in my office and I'm having difficulty partying with them. Much like the Altec A7 Voice of the Theaters that I kept in my garage for a year. I refinished those. They two had a great, but unique sound.

I can see how phase issues can be a problem. Yeah, JM Lab has used that inverted tweeter for awhile. I really enjoyed a pair that I had awhile back. If there was a perfect answer we wouldn't be having this discussion now. That's what makes this hobby so unique. As soon as you get used to one thing, you hear something a little different and you perceive it more pleasing. Whether or not one is better than the other is up for debate. Especially when you get to a certain point. There are trade-offs for everything when it comes to audio. FUN, FUN, FUN!!!
