I was given these parameters i gusse you could call them to build a 2-Way speaker using the dc200. Any ways my gusestion is in the crossover portion. I was givin all the parts but a schematic would be helpfull for assebly because I am very new to zoble crossovers. But anyways could any body build a schematic so i can asemble a shematic using the given parts below thanks.
Here ya go:
Box: 3/4" MDF, or even PB works fine. Line the inside with convoluted foam
(Wal-Mart mattress pad works great). These are outside dimensions (inside will
be 1-1/2" shorter) for a 1.7 cf ported tower. Width = 9", Depth = 13", Height
= 35.5". Mount the tweeter centered so the top edge is 1" from the outside top
of the cab. Mount the 8" woofer centered below it (the closer the better). The
port tube is 3" i.d. and 9.25" total length. Mount it centered below the
woofer so its center is 13" above the bottom (floor). If you have a router,
roundover both inside ends of the tube (1/4" roundover bit) or at least the
inside of the front of the tube at the baffle.
Crossover: 2nd order HP with L-pad.
series cap: 5.6 uF poly
shunt coil: 0.50 mH 20# (Jantzen is good)
series resistor: 4.7 ohm
parallel resistor: 7.5 ohm
1st order LP with Zobel.
series coil: 0.50 mH 18# (Jantzen)
Zobel cap: 47 uF npe (like $1)
Zobel resistor: 4 ohm
