Crossover for Altec 416-8B , 806-8A , 811B

I just got the above said combo and cabinet are also ready
what missing is a crossover for 8 ohm 800hz !

Since I'm new and need your help to teach me how to DIY a crossover
a crossover to make it sing! Now I have the speaker cable from
the power amp direct input to the 416-8B woofer without any coil or cap and the 806-8A with a 3.9uf cap , is this correct ?

Please help and thanks !

Try diyaudiovideo.com and go to calculator. Values for Linkwitz_Riley is 8.29 UF for tyhe caps and 2.12 mH for the coils. The calculator shows the schematic for wiring. Remember the heaver coil on the woofer and better cap on the horn. The resistor value is up to you but I would try various values from 1/3/5/7/ ohms and use the one you like best. Try parts express if cost is a factor. If you wish assistance try Madisound as they can design and build them if you wish.
