Hello, I have some old 70's peavey sp3 speakers. 2 way 15" with 22xt horn.
The cross over point was 800hz.
I want to make it 2000hz.
The stock woofer was a 4 ohm, the new one is a black widow 8 ohm.
So...
I need the right caps for 2,000 hz crossover at 8 ohms horn and woofer.
The issue is the woofer was 4ohm and now 8 ohm. I'm not sure if that affects the value.
CAPACITOR 25UF, 100V
CAPACITOR 4mfd 10% 200 vdc
Resistor, power. Resistance: 500 Ohm. Power: 10 watt. Tolerance: 10%. ( I think that is what it says for sure 10%)
new ones from calculator this is what I found...
1st Order Butterworth
2000 Hertz
8 Ohm Tweeter / 8 Ohm Woofer
Parts List
Capacitors
C1 = 9.94 uF
Inductors
L1 = 0.64 mH
will these work?

Would I be better off replacing the whole crossover with a new dayton 2000 or something? I think it won't work with out an l pad then though correct? The old crossover has that rectangular stone and a transformer looking part on it.
You want to change not only the crossover point but also the impedance, I would vote make a new crossover entirely.
I want to learn with these.
I have had anything from bose 901 series 1 to K horns, ess heils etc...I know they are not great but I like them.
Carbon Tracker firestarter no Joke...So I"m not sure what arced but blew heater and plate traces up the top now either or 470R let go it's reading like 5k now lol...jumper and clean this up this thing here man Lol

How do you know? That is the proper crossover frequency for a 15 but not many 1" exit CDs can go that low. And PVs own documentation says the recommended crossover for the RX22 is 1.2khz at 12dB/oct minimum so something doesn't add up.
OK you're going in the right direction but why 2khz?
