I googled the Zenith drivers and found them on a Chinese (!) site for $30 and $10 shipping!

Did some looking into it and they seem legit, even though their main activity is women's fashion.
I bought the pair—wish me luck!

I hope that site is legit, they are still available to buy one week after your post!

Any news on the Zenith?

Any news on the Zenith?

Funny you should ask. I sent them an email 8 days ago querying my order, but have had no reply to that yet. Just now I saw on the VISA statement that they processed the order on Mar 11 and I sent them another email query.

I see what look to be the same pair of Zenith drivers advertized on their site, but allow for the fact they may be slow modifying their page.
It's a little too early to panic; 5 weeks is not unthinkable for large-ish boxes coming from China. I'll let you know!

Their IP is from US but their ABOUT say no country, city or address.

This is a work in progress. The woofers are GR-Reseach OB/W 12". The mid/tweet section is something I cooked up from a wild imagination and a distinct lack of knowledge.

The woofers from Parts Express & tweeters from China. I used XSim to design my tweeter based on MFR specs on the woofer and NEO 8 specs which is similar to the tweeters. The good news is the tweeters have a much gentler rise starting at 8khz.

I've gone through several iterations over the years...  Here's some pics of most of them.
First try:

More pics at http://n4rp.com/dipoles.html  I also did a version of this with Altec 604Gs on the baffle, but I can't find any pics.

Next step:

Dayton PS220-8 on a JEL style baffle.  Not my woodwork

Another step forward:


A major step in the right direction:

With a build thread here: http://dcaudiodiy.com/phpBB3/viewtopic.php?f=4&t=566
Which evolved into this:


And then:


And, as of last night:

with some more information available on the second page of this thread: http://dcaudiodiy.com/phpBB3/viewtopic.php?f=4&t=819

I remember threads talking about the validity of most of those. Very cool!

What drivers did you used?
Thank you!

[Bob in St. Louis]

What drivers did you used?
Thank you!

A lot of really big ones, a few medium sized ones, and a couple itty bitty ones.
Hope that helps!

An update:
Yup, it was a scam. My account was debited immediately, but the goods never arrived and now the site appears either to be down or operating with a different identity. Luckily I lost "only" $44 CAD. I'm still glad I found out about these drivers and will pursue them from more legit sources.

These are my new OB Speakers. They are GR-Research NX-Otica monitors mated with GR-Research/Rythmik dual 12" H-Frame OB subs.

The NX-Otica monitors use the Neo3 PDR tweeter in an open back configuration and GR-Research M165NQ woofers. The NQ woofers were designed for open baffle use.

The subs use two of the GR-Research SW-12-08FR woofers and a Rythmik A370PEQ3 amp each.















The pictures are right side up on my computer. I don't know why some like to turn sideways when I post here

Whatever software you're using to view them at home is probably smart enough to read the rotation meta-info in the jpg and auto-rotate it.  If you edit and re-save the pics in the correct orientation before you post them that MAY fix the problem.
