On the BMS 4590P is a filter attached. The BMS 4590 comes without.
As i want to use more audiphilic components for it i have not ordered these filters.
Who can tell me what the setting of these filters is?

I know these responses.. First i had ordered an 4590P aswell but that company did not deliver.. Later i bought these drivers at a company that did deliver the 4590 fast but could not deliver the 4590P
That's why i want to peek into this PCB,..

Hi,
I just bought a bms4590.
Anybody has a good/somple crossover schematic for this driver?
Best,

Hi Winslow...
Good! I am preparing thing to start a Horn project for my living room.
I will be using a JBL2360A horn and the BMS4590.
I want to use a passive crossover so I can use a single SET 45 amplifier for mid and highs.
Later I will use active crossover to mate this setup with a woofer.
Are you able to determine the circuite schematic that was used?
To me It looks like a 2nd order crossover, something like this?
Passive Crossover Design Equations Formulas Calculator - Two Way Second Order Network Chebychev Bessel Butterworth Linkwitz-Riley
set for 8ohm drivers and a crossover of 6.5khz?
Are you able at least to determine the number of components and values for some of them?
Maybe a photo of the front and back and determine values for some of the components.
Thanks in advace!

Someone got results with a passive filter for this driver?
I've been reading this tutorial:
Passive Crossover Network Design
And thinking about implementing a 2nd order filter at 6.3khz

It looks like a 2nd order on the mid driver and a first order on the HF- there are only 3 components on my passives. The only one with a readable value is on the MF- a 3.3uf cap and unknown value coil.
That's good info Winslow, thanks.
I will try to play arround those numbers.
I wonder what would be the reason to choose just a first order low pass crossover for the HF driver.

Playing a little bit here:
Passive Crossover Design Equations Formulas Calculator - Two Way First Order Network Butterworth
Seems like the 3,3uF Cap corresponds to the first order crossover for highs.

I liked them, I had the 4591s which were the mid only section. I sold them back in 2006 or so. Played them for a while in my apartment with low crossover on the lowend at low levels.
Well 6.3k is pretty high and they are really robust drivers, that's probably all they need. And with the horn loading, the 6 dB electrical filter probably comes in about as a 24 dB acoustic filter...would have to play around and see.
I like to use the demo version of LspCAD and Jeff Bagby's Passive Crossover Designer spreadsheet...very powerful and can do more than those online calculators.

There used to be a crossover for these drivers posted on Audio Asylum...but that's been 7-8 years back and the schematics are all gone now. I had/have them saved on my old computer and had emailed them to Jennifer Crock over at Jena Labs.
Maybe contact her to see if she still has the design?
The fellow that designed that circuit goes by RCA-fan on Audio Asylum.

Thanks for the example Maxtube.
The more i read the more I realize crossover is horn dependent.
Guess I start simple and measuring...
