Selenium D250-X GW 1" Phenolic Horn Driver 1-3/8"-18 TPI
What crossover do you recommend for this? I'm using an eminence 15 lfa woofer.
To avoid beaming issues, I would not cross a 15" woofer much higher than about 800 Hz. Since this driver can handle a crossover as low as 500 Hz, anything between these numbers would work well. If you are looking for a two way design, something like below would work well.http://www.parts-express.com/eminence-pxb2-500-2-way-speaker-crossover-board-500-hz--290-630

What happens to power handling if a 24db crossover is used at say 500hz
The power handling will increase a little, but I cannot give you a specific number. Even 100 watts RMS into this driver will be plenty for most applications.

Would it be possible, or advisable to parallel a piezo tweeter off of these to extend the frequency range for use as a midrange cabinet driven by a dedicated amp and used with an active crossover?
There's nothing wrong with doing this. You will have to play around with the number of piezos that would match the output of the mid the best.

I am building a bi-amped system using an electronic crossover. I am thinking of using these horns for the midrange/tweeter speakers which will be driven by their own amp. As these only go up to 9000 Hz, what can I parallel off of them to extend the range
You will not want to parallel these with another different driver, these will need to be used on their own as a dedicated midrange and a separate tweeter will be needed.

will a 1,647khz crossover be fine with the horn driver?
Yes. low response is 400Hz with a recommended crossover of 1000Hz and above.

What is your opinion to using it for a 375hz Smith Horn? Also since this is thread mount, is there an adapter made for the threads to mount it?
The lowest crossover point that is recommended for this driver is 500 Hz. If you need something to play as low as 375, you might consider something like the Dayton D1075T, which has a 16 ohm bypass and can play safely down to 300 Hz. We do have thread adapters available, but only for standard 2 or 3 bolt mounts.
