Goldwood GT-1016 2" x 5" Wide Dispersion Piezo Horn Tweeter
I would like to use the horn on this unit but remove the tweeter and use another brand. Can I remove the horn and if I can, can I replace the Piezo tweeter with a 1" threaded tweeter from Eminence?
No this tweeter is piezo only, it will not accept a threaded mount type horn driver.

Do you have a cover for this speaker
Unfortunately we do not have any covers for this tweeter.

specs on the 270-041 is 5 3/4 x 2 3/4 . Is this the overall frame or the required cutout I have a cabinet that has a hole 6" x 2 1/8"
The dimensions for that tweeter are overall so it would be too small for the cutout you have. A closer option would be the Goldwood below, which has overall dimensions of 7-1/4" x 3-1/8".http://www.parts-express.com/goldwood-3-x-7-wide-dispersion-piezo-horn-mid-tweeter--280-062

Is the Back Removable?
Does the back separate from the horn housing? I would like to paint the horn housings, but will not do this if I can't separate the horn from the electronics.
yes :-) just 3 screws and it all comes apart. they are very simple.

Impedance of piezo tweeters, and crossover cap values
I have some experience with these; most economy piezos are created equal [all have them same 3/4" wafer inside].Cant beat 'em for the money fer sure, they generally dont require crossovers and are bullet-proof. But now, I am replacing them in 2-way FR boxes and wish to "unload" them a little with thier targeted frequency range [2-20Khz], to make them brighter [is there any point to this?].They measure open [ohm-meter] but I have seen a spec on similar ones putting them at 75 ohms. The originals had 47uf NPE which are off the 8-ohm 1st order [6db] filter chart [2-ohm/1800hz uses 44uf, but these aint 2-ohm], so have no idea where they are crossing over without measuing equipment. What cap value do you recommend and would you use a 20-ohm resistor in series or parallel for loading/amp protection [200W/ch]?note: I wish to use these or the higher-pwr Pyle version below...
Piezo drivers have a different impedance at different frequencies, not a set or nominal impedance. The lower the frequencies, the higher the impedance. This is why no cross-over is used and you cannot use normal formulas to calculate. This is why it measures infinite resistance with a ohm meter, because you are applying zero hertz with the battery in the meter.

How many piezos per box/case?
One to two with an lpad to control them
