If it's a new variant, then it's not the DX25TG59. If you mean the new (@PE) Tymphany/Peerless aluminum dome, then that's the DA25. The DA25 has been out at MAD for about 2 years now, maybe more. PE just didn't pick it up until recently, and IIRC, it's cheaper at MAD. Of course, the new double-magnet version looks mighty tasty as well.
I agree that it should be a good unit, and I've heard it a few times now with pleasing results.
The RS28 was a good, scratch that- Fantastic(!)- tweeter. It was very low HD, few tweeters are more capable than it was in terms of extension, and the price was good to boot. There just aren't that many tweeters that fit its particular niche or price/performance. I don't think we're mourning its loss. I believe we are just wondering what the next tweeter will be that slides into its well-regarded/$ position in the tweeter hierarchy. FWIW, my money is NOT on its replacement at this point in time.
My concern with the Tymphany is the odd order distortion below 2K (despite the low FS). I do like the Tymp tweeters, but want something in the 1.5K range.
Right now I'm leaning toward the Seas. I hope to measure the Wavecors in a few weeks
Even the base version of the DX25 exhibits very low distortion below 2K, John. I imagine with the better chamber and larger motor, the BG60 version will do even better.
I am ordering a pr of the dx25bg60 tonight and a couple of wavecores for testing. If I can get into the dungeon, I will test next week. Having my knee scoped tomorrow so we shall see.
On the topic of wavecor, I recently found this post of a breakdown of the TW030WA11. Not the cheapest tweeter out there, but it sure looks like you get your money's worth. Extended pole peice with lots of copper, lots of air space and lots of damping, and an above average size 30mm dome, what more could you ask for?
I want try and cut a baffle with a waveguide built in. Looking for good candidates. The flangeless xt25 is interesting. Flat faceplates help if the cone is protruding. If anyone knows of any other inexpensive nice sounding tweeters that would be a good candidate im all ears.
What I find more interesting is that Tktran (posted in same thread) visited Usher's new retail store and reported Usher is alive and well. They apparently are not out of business as reported. Since the RS28 and Usher 9950 are reportedly interchangeable, it sounds to me like a supplier disagreement with PE and a new US distributor is needed for Usher products. CCS perhaps?
Anyone else have more info?

I heard through the grapevine that Usher is doing so well that they wanted about double to continue producing the RS28 line, and PE didn't agree to it, thus finding a lower cost supplier to make the new ones.

Thanks for the info. I'm not surprised. The RS28 was a hell'va tweeter at that price point. At $100, the competition gets much tougher.
FWIW, Curt is working with Meniscus to update the Finalists with a Morel tweeter that's comparable to the RS28. Curt is as always super busy so I'm not sure how soon that will be available. I doubt anyone here is on the edge of their seats waiting to build the Finalists but some may find the differences in crossover between the RS28 and Morel replacement of interest.
I know there are lots of great tweeters out there, but one reason I think to mourn the loss of the original rs28 is that there is a very nice purpose made waveguide readily available for it, on top of its already nice low crossover performance. Be interesting to see the secs on the replacement and how it performs in the seos.
i wish a lot of these nice new other low-fs tweeters like the dx, sb, etc. had flat face plates or a flat alternate face plate option for easier waveguide mounting. The flat face of the rs28 and h1212 is a nice thing for this purpose IMO.
Im going to work on a round wave guide for the CSS LD-22 and DX25BG if im lucky hopefully the dx25 will work with the xt25 as well. No certain time-table at this point as i dont know how much testing and fiddling is going to be involved with it.

I contacted Usher directly and was told that they are out of the driver build-house business.
Okay- that sheds some light on the subject! Looking through many of the tweeters that have copper infused in the motor, the FR rarely exceeds 90dB nominal for those kinds of dome tweeters, so this was a hunch on my part. Copper sucks out so much Bl that the sensitivity goes much lower than without it. I'm happy with this surprise!

I really like the DX20, so hopefully that carries over to the DX25.
I hope to stress the BG60 variant this weekend.
So no need to link unless someones got the new DX25BG60 driver measurements.

Pry the faceplate off that bad boy and see if you can wavertize it. I bet it would be swell.
Maybe you have seen this thread

Never mind - saw Javad's comment about Usher doubling the wholesale price. Either scenario works.
RS28F-4 0-45 deg
These are the samples that we measured... If you ask me, they look quite a bit better than the original RS tweeter.
Jim
The damped high end on the Al is impressive, no artifacts in the off axis measurements.
Who do I need to call to get on the list?
