3 way crossover design advices

[WhiteRhino]

Did you engage hilbert transform in XSim for phase calculation of the files that don't contain phase data? It appears you did not.

I will read how to do this and update you .

 

[Lojzek]

I can work on this crossover if it's ok with you. Let me know.

 

[WhiteRhino]

Yes sure Thats ok .

 

[Lojzek]

Give me a few days, I need to start from the ground up. I need exact baffle measures, internally available volume, panel thickness, exact driver positions on the baffle or shall I decide where drivers are to be positioned?

Good luck with that Goldwood Lojzek, it's a doozy

 

[Lojzek]

Right, good luck Rhino when you see a 20 parts filter in the midrange section only.

 

[WhiteRhino]

The sealed box can not be change , I allready order it should come to me soon .
thanks

Right, good luck Rhino when you see a 20 parts filter in the midrange section only.

parts for cross over are cheep no problem with that . after your design I find some money and order it and test it .

 

[Lojzek]

Ok, this is the baffle data I will be using in a sim. They are modified compared to yours because it seemed more appealing.

 

[WhiteRhino]

I have to stick with mine baffle data as shown in the previous picture .
Tweeter hole is 5 cm . I going to put the tweeter inside the box to fit .
Midrange hole is 10 cm .
Woofer hole is 28 cm .

 

[Lojzek]

What are you trying to say, that tweeter will be protruding from the inside of the enclosure through a 5 cm hole diameter? The baffle opening will be treated in what way?

 

[WhiteRhino]

The speakers box is going to be as mine picture .
The woofer and midrange will placed normally at the outside .
Because the tweeter hole is 5 cm , and i don't want to enlarge it . so I will place it inside the box . like a 5 cm horn .

 

[Lojzek]

Here you go. Network of R5,C6,L6 may not be necessary. Have fun.

 

[WhiteRhino]

thank you very much Lojzek . do you have maybe the dxo file for the project ?

 

[WhiteRhino]

Ok looks like you made the circuit well done , but it is not normal to build such big circuite perhaps we could make more simple circuit . or maybe replace the midrange to more suitable driver
here is project it should look like that ?

 

[WhiteRhino]

I tried here to minimized the cross . can we trust this circuit ?

 

[AllenB]

Are you using the same files and configuration as Lojzek?

 

[WhiteRhino]

No. that would be great if Lojzek apply them to the forum .

three-way crossovers are almost always big and complex if done properly.
you might be able to simplify by using a midrange with more flat response, but i doubt that.
considering that mounting the tweeter from behind the baffle is no good idea (unless you have a precise idea of the waveguide you want to build) and you want to simplify the project and use the existing enclosure and the woofer you might be able to change the project to a two way system with a 5" fullrange and a low crossover frequency.
maybe something like this: 10F/8424 & RS225-8 FAST / WAW Ref Monitor

This is the best second order I could make
