Huge !

Man this is the biggest tweeter i have ever had it weights 2 pounds easy and as you can see it bigger then the CD case. I think i am in love. Till the 4 10's show up.

What are these and what project are you putting them into?

Is that a Hi-Vi? If so, which?

That's no tweeter! Here's a tweeter, all 12 pounds!

that is a cool tweeter. Do you know if the back plate can be removed ?
The purpose of this could be either:
- make it operate as a dipole
- place it a bigger designed enclosure to getter a wider frequency range (in the lower region). The f3 of this thing is rather high 1-2kHZ as I recall.

Unfortunately i dont think it will even be x-over anywhere near that. I had a couple suggestions and i think ill let it live above 3k. The morel runs up that far.

Nice ! too bad i cant afford it

Can you have a look and check if the back plate can be removed ? If crossing over as high as 3kHZ, you might be better of with a smaller planar or ribbon. Judging from the size of it your tweeter, it looks more like a midrange, thus beeming at higher frequences might be an issue, it might also lack a little in the very top end.

It is a mid/tweet. Beaming in a ribbon i have never heard of and ya the plate comes off, i am not going to take it off though

I am only crossing over so high to avoid the verboden region where no crossover is supposed to go. Kinda like space.

By the frequency response curves given i think the roll off near 18k wont bother me much. I wanted fast to match a fast woofer which matches my fast subs. Pretty low moving mass on the 10's i bought. If it all falls to peices and after a few months i cant get it sounding right ill rebuild it or buy a super tweeter and play with it that way.
