WHD mid dome? Any good?

Leffemannen · 29th December 2005, 08:52 PM

WHD, 2" (CAL 50) midrange domes. Are they any god? There seam to be next to no info at all on the web on them.

The intended use is ~900 hz to 7 kHz. 2 Hds 164 at the bottom and a god 2/3" tweeter (or maybe I will try a CTS piezo horn, cut HIGH...) at the top.

Hi Leif,

I couldn't find anything resembling that driver either, but I do like dome mids. I am using some 2" ers right now and am happy. Can you post a pic or two of the mids?

Also, I'd stick with a dome tweeter for the dome mid. To me, piezos are for when you need a cheap PA tweeter, you can't afford a real tweeter, or you're looking to punish the dog.

If you've got a pic, maybe someone can help identify it.

Hi Cal,

Here's a pic: http://home.swipnet.se/Karlssons/speeker/CAL%2050.gif

Well, since I don't have a dog...

No, but seriously, Im 32 so I have more less grown up with them (piezo), and while they lack allot I believe at least some of it's bad name comes from people using them without xover (105 db piezo horn + 87 db 10" woofer, maybe with a coil on the woofer...) What whey do have is some resolution & detail that I like.

That said, a small titan dome is a more likely candidate...

BTW: What middome do you use?

WHD was a German manufacturer that was quite fashionable (components and kits) at the end of the seventies/beginning of the eighties. They were in approx the same quality category as ITT drivers for instance.

I don't know if they are still in business though.

I have corrected the title of your thread. However if you meant that this dome was truely worth worshipping as a deity, then I'll change it back.

Leif,

I'd have to confirm with planet10 but I believe it is a Coral. It came from this set.

Oh and about the piezos, I used to use them a lot as I wasn't exactly rich in the old days so piezos were fine. Now that I don't have to use them anymore, I don't. The detail is nice but the sound is unnatural to me. Great for parties but not for serious listening.

And this is where they ended up. This is the front and back of my "quiet" system
