Not sure I fully understand 
but I think you are saying the tweeter makes this sound when the crossover is attached back in the cabinet. And the sound comes "from the tweeter".
Could the tightening of the crossover be distorting the cabinet and consequently the distorting the tweeter frame. Try loosening the tweeter fixing screws to see if it helps isolate the problem.

yup - common problem of generic answers
now seriously - due fact that HPD is coaxial speaker , there is no possibility that deformation in speaker baffle is causing funny noise from tweeter
OP needs to post pictures , so we can see what type of xover he is having , so we can proceed with analysis
Could be one of the parts is "microphonic" probably a switch , try tapping the parts with the plastic back of a screwdriver to isolate the problem .

caps are good , mostly
so - knowing that there is enough info - google for rejuvenation of Tannoy xovers , and you'll find how to disassemble switches ; whatever , it's simple enough and you'll figure by your self how to do that
disassemble them ( taking enough pics here all the time , so you'll have enough info for proper re-assembling) , clean all metal parts with acetone or medical petrol (benzin), let them dry , put some vaseline on contacts , re-assemble them , put back on pcb and solder
while you there , clean all solder joints ( either with vacuum pump or solder wick) - work one by one ,and solder again
if wire ends are looking dark and brittle - either replace wires , or just short them by 5-10mm , blank isolation and solder again
that will solve intermittent contact problems

thanks its working now
hello and thanks for your good advices
I solderd all points on the crossover new, I mean I went with my soldering iron to every point and reheated, so it was melting and if there was not enough solder I put on, now its working, no cracking or strange sound
thanks
