Aurum Cantus AST2560 Aero Striction Tweeter
Is the rear of the magnet open-vented on these- in other words, do they need a sub-enclosure when sharing a cabinet with a woofer/mid-woofer?
I'm running very loud professional mid-bass drivers with efficiencies from 96 db to 99 db. Will this work? Is it possible to use tweeters with lower efficiency with higher efficiency speakers?

lowest 2nd order x/o point?
I see it says can be crossed at 1900 hz, but just checking as it doesnt state what slope. Thanks
That would probably be for a third order crossover if I had to guess, but what I think they are saying is that it wouldn't damage the tweeter if you put your 2nd order high pass at 1900 Hz. I would think that you would want to go a little higher than that though since its frequency response range only goes down to 1600 Hz. You want to always maintain at least one octave of seperation between the speaker and the bottom or top of its range if you can help it.

If used as a monopole, what kind of chamber would be best?
In their original speakers these sounded great, but I haven't seen the cabinet specs.
These do not require a chamber in the rear since they are already sealed.

How is the vertical dispersion of these type of drivers,do they "beam" like ribbon drivers
No they do not beam on the vertical axis. Please read my comment on the customer reviews. These are very fast drivers and they store very little energy. What is most important is what mid-range or mid-woofer are you using to avoid a speed mismatch between drivers. If you are building a two way, I would go with the bigger units and cross over much lower, as low as 1300 hertz with a Linkwitz 2nd order crossover or use a dome tweeter. If you are doing a three way this tweeter can cross as low as 2500 hz. Remember to invert the phase on the tweeter for second order crossovers. good luck Ralph.

Can rear felt be removed for bipol/dipol applications?
Is it possible to get a pic of the rear without the rear felt?
While it may be theoretically possible to pursue such a modification, it's not something that we can do here, unfortunately. Doing so would most likely void the manufacturer's warranty.
