need crossovers for theese speakers Szerokopasmowe
and G?o?niki
i want bandpass on full range speaker from 50hz to about 7khz(because full range frequency response is 51hz to 13.5khz he cant produce very low bass and it may distort quality and for tweeter just high pass from about 7khz ,do you combine theese two crossovers into one or for each speaker make separate one ??? how basicly u make them ?? my friend will try to make them he never made crossovers before he can make them by using calculators and formulas... p.s. i tryed run this setup in closed box withouth any crossovers and tweeter had burning smell,but seems it survived .... also is my choice for cutting full range speaker is allright ??? or i should let him get more highs ?? in data sheet full range speaker on frequency graph shows some kind of downfall in about 3.5khz is it normal ?? or maybe better i should use piezo tweeters for this setup ??

Okay, I'll bite.
First off, all tweeters need protection. They have tiny voice coils, so running them without a crossover will cook them quickly, as you noted.
Next up, use a different tweeter. The one you've linked is used in small home stereo systems, and won't survive PA use. Piezo tweeters can be made to sound good, but its not easy.
If the wide-range speaker falls off at 3.5kHz, you need to bring a tweeter in there.
You do realise this is posted in digital line-level, right?
Are you going to use DSP or an active crossover, or a passive (speaker-level) crossover?

i mean it has a little pit in the frequency curve u can see for your self in the bottom of page press on EMKAudio PA12300C8HW it will open pdf file,i think passive speaker level crossover ,i do have piezos too 100w peak power 2-20khz but cutting at 3.5khz for full range is kinda waste ...
