I bought some binding post with 4,000 crossovers attached. They were so inexpensive that...I can remove the crossover & only use the binding post & I'm still ahead. But...I need a crossover for 2,000 or 2,500. Is there a way to convert these 4,000 crossovers to 2,000 or 2,500?
It will take me a while. Could you keep an eye out for it?
I'm new at this but. I can figure the board out & draw one.
Thanks...

Ok, what you will have to do is double the values of some (but not necessarily all) of the capacitors,
to go from 4kHz to 2kHz.

> go from 4kHz to 2kHz
He asked for 4000 to 2500.
The transposition is 4000/2500 or 1.6.
If it is a simple L-C crossover, make all caps *and* all coils 1.6 times bigger.
"Problem" -- the caps and coils are typically the most expensive parts. You can probably buy a ready-to-go crossover cheaper than you can collect the bits to replace or shim-up the existing coils&caps.

The drivers that I'm working with are RS100-8-4" & tweeter Goldwood GT-510 1" (with a capacitor). Together they sound crystal clear ...but have no bass.
It sounds like trying to modify these 4,000 crossovers is lot of hassle & no savings.
Thanks for the help. I will take the components off the crossover & save the parts for a future build.
Do you guys have any recommendations to try to get more bass....I have ordered the components for the baffle step correction. Below are specifics of my build.
I'm new at speaker building...trying to learn.
vented value is .13
baffle width is 4-1/2"
port size 11/16"x4-1-/2"x13" long (as recommended by Parts Express)
Thanks in advance...

4kHz is a perfectly fine crossover between a 4-inch and a 1-inch.
> no bass
A 4-inch is NOT a woofer. If forced it will distort. Speaker mechanics have got some better in 70 years but you can't fool Mother Nature. Note that the first good "living room speaker" was a Six, and that in days when music was not bass-heavy.
The for-real bass to go with a 1" and 4" would be a 16" (see the pattern?) in a small dog-house. You can find examples of 10, 12 and 15" woofers to copy. Crossover may be 400Hz to 1600Hz depending on cleanliness versus robustness. Of course then your 4-inch's enclosure can simplify from a long vent-box to a margarine tub.

Thanks for the reply.
I will temporarily connect the 4,000 crossover & see if it works...if it doesn't...I will put things back the way they were.
