Hi all
I'm building an high efficiency two way loudspeakers system.
I have two 15" 4ohm 100db woofers and I have to buy the tweeters.
I like Fostex supertweeters, and so I'm searching something similar 4ohm and cheaper. I found the pyle PDBT35 and the Master Audio TT800 or similar can be good, but on the internet there are no frequency response diagrams. Do you know this components?
Sorry for my english!
Thank you
Simone

Same question.
There will be a big frequency range where neither the 15"ers, nor the bullit tweeters will be able to perform well.
A dedicated midrange driver is probably going to be needed to fill that range.
For high efficiency, that mid range will need to be a big speaker, maybe 8" to 12", just to get a sensitivity and power handling to match the other drivers.
Consider that I like full range speakers and also tannoy speakers, but thank you for all your opinion, I will think about it.
This is my woofer response:

An externally hosted image should be here but it was not working when we last tested it.
Oddly enough I love Tannoys but I really do not like 'full-range' drivers at all. ;-)
The problem with Pyle is that it's cheap. Many of their drivers are far out of spec. You never know what you will get.
I agree with the others. Matching a bullet tweeter to a 15" is going to be difficult. I've heard pro 18" drivers and dome tweeters work well together, with the right crossover, but the bullet and the 15 will be a tough match. Good luck!

Thank you Pano for your advice. I'm searching something similar and I found the Ground Zero GZCT 0500X that has also the frequency response diagram in the manual. Competition GZCT 0500X
You are welcome. You can probably get those to work with your woofer, but I doubt it will sound great. Be sure to protect that tweeter if you play loud.
I do doubt you'll be very happy with the results, but this is DIY. Give it a try, you will learn a lot - and that's important. Then if you want to add a midrange driver later, you have a good start.

Forget about your beautifully looking FR diagram. It's not even half the truth. 
It doesn't even show off-axis response. With a 15" you'll need to cross between
1000 and 2000 Hz.
It's hard enough designing a two-way with a 15" and a really good mid-tweeter.
If this idea should have some chance get a horn-mounted 1.5" driver which is up
to crossing below 2K.
