I've got the tweeter in an test setup with the 830656 from peerless, crossed at 3100 Hz with a 3rd order crossover. And they do sound great allready, still have to break them in....

But the sound is far better then my old tweeters (Visaton G25) more high and good detail of music. Parts used for the crossover are the Clarity Caps PX 250V with a Vishay MKP 1837 0.01 uF bypass cap.

And seen from the tests they have low distortion, comparable to the XT25 and with a bigger sd surface then the XT's.

See: http://www.diyaudio.com/forums/showthread/t-97043.html

But indeed from that test you could choose the Peerless HDS, but at a bigger price.

All in all, I am very content with the DX25, sounds great, build quality is great and looks amazing...

In what setup would you want to use this tweeter?

Dank uw voor de reply...

I dont want to use the tweeter in a design - it is already employed in a set of speakers I bought. The tweeters gives me a headache! I cant listen to the speakers. Note that the speakers are made by a company that specializes in manufacturing quality speaker systems.

What brand are they?

Can you get the crossover specs? Or can you see what the crossover looks like? If they are crossed to low they would sound fatiguing.

And have you tried to set the speakers 25degrees of axis of your listening position (tweeter not facing you directly)...

Can you describe what the sound is like, does it sound to harsh, have you broken them in allready (100hours or so).

If they sound to foreward in the treble, the frequencies from 2500-4500 can be a bit to high... Do you have a way of measuring them with a program?

It's kind of hard to see the problem right away from your description.
More info please..

For sake of keeping peace I would not mention the brand or model nor place pictures.
Mid/bass is a 6.5" Vifa unit.

The vocals on music is extremely brash and forward!

The set is ~4 years old so they are well run-in.

I cant measure them unfortunately though I wish I could.

I did try various positions with tweeters inside and out and against the wall etc...

Maybe I could PM you the pictures of the x-over and such... or e-mail?

Sounds like a crossover problem, but anyways:

You've got an PM...

I've used them, and I thought they were okay, but not the best choice out there. The non-ferrofluid Seas units (if they still make them) and low end, with chamber Morel tweeters are much better in my opinion.

I'm guessing that it was a bad pair or the designers did something very wrong. That does not sound like the DX25 tweeters at all.

DX25 is quite good. You just have to make sure you don't push it too low. I've got a pair crossed over at 2700Hz with a 2nd order AR-series and no edginess or head aches.

Get it wrong and they will bite, but that applies to a lot of tweeters.
