I know how to solder,I have drawing of 4th order linkwitz-riley at 2650hz.I just need recomandations on which type of capacitors and inductors to use.I would like to stay in the $200 range for both.I see certain one's for mid or certain for tweeters but am lost.I looked at Clarity cap for capacitors and solen perfect lay for inductors.Can they all be the same or do i need say polypropelene for some and not others.Thanks all help appreciated

Hi,
cheap polypropylene capacitors will do the job well.
Once you have the speakers running properly then, you can try exotic (=expensive) caps, but you need a reference first or you'll never know if you're better or worse or the same.
Get the voltage adequate and combine values (parallel) to get the total to be correct.

Use air cored inductors if you can afford it. Whether coils of wire are different from coils of strip, I don't know. Again comparison is the only way forward.
If you go for ferrite cored then ensure that the inductors have more than adequate power handling. Excess current changes the ferrite cored inductance and then the crossover points change drastically if over driven.

4th order L-R. How are you achieving that passively?
As the filter orders go up the acceptable component tolerance becomes much tighter. Most cheaper speakers stop at 2nd order.
Most expensive speakers stop at 3rd order and by then drivers have to be matched to components to maintain balance between channels.
