WTB Apex Jr. Ribbon Tweeter
 
Hello all,
I am looking for a number of a ribbon tweeter sourced from Apex Jr, manufactured by Fuji Sanwa, AFAIK. It's a spiral coil on the ribbon, constrained between two magnets with a waveguide and perforated metal protective grill.
Anyone who has these to spare, I'd greatly appreciate it. To Planet10, I already contacted you via email, so no need to repond here as well.
Will pay reasonable prices.

Thanks all!

Hi Badman-

Doesn't Steve have any more?

"Doesn't Steve have any more?"

Nope. But that he did! But, no joy there. His 1200 (!) units sold out, somehow.

WOW! I figured those would be around for a while.

I bought 3 pair a while back and they are still awaiting the fabrication of the enclosure they are to be placed in.

May I ask what type project you used them in, and what X-over you chose?

6 units? all for a pair? Lookin' at high sensitivity I guess. And yes, you may ask, but I may not answer :devilr:


Actually, the project is a little wierd, it's a 2 way with a series XO, using an MCM 55-1200 4.5" midrange. I used a high tweeter cut-in to damp that peak and level match the midwoof. Enclosure is .55 cu Ft. ported, port tuned to 65Hz, IIRC (been a while since I calc'd it) . I'll probably try a sealed enclosure with the same XO to get better integration to the sub... but I'm going to eventually also need to get stereo subs.

Actually I bought 6 units for "what ever"... The price was good and they looked interesting.

So you are using series XO... Ok.. I was going more conventional with parallel.

Let me know how they end up sounding and I will do the same.

I am actually planning on using them with four 2" drivers per speaker to make a desktop line array for my computer.
