Wow perfect !! Thanks !Maybe this will help
Crossover Calculator
This crossover calculator will help you design amazing sounding speaker units.
Let me suggest this crossover program:
Do we need to do some measurement like vituixcad ? I don't have a calibration mic yet.Let me suggest this crossover program:
XSim free crossover designer
I'm announcing the public release of XSim, a "free-form" Windows-based passive crossover design and simulation program intended to be as intuitive and non-restrictive as possible. . The program is ***free*** for personal or commercial use. Any speaker builder with at least a basic...www.diyaudio.com
I used it awhile back to modify a system I built a long time ago, with great results.
It's easy to learn, and will show you graphically the response created by your changes.
You input the speaker parameters, and create your crossover schematic and you get an instant graph of the response.
Very useful, and fun to play with different component values and what response is created.
No measurements needed to design your xover. But you do need the speaker parameters to input into the program.
Even if you don't actually build a xover from xsim, it's a lot of fun to try different crossover components and types and instantly see the response and how your changes affect it.
Without impedance and frequency response measurements for the individual drivers, and using those in a suitable model (e.g., using VituixCAD), it is an uphill battle trying to get a smooth crossover transition.
Yes I know, the driver that a choose have some parameter disponible on internet and for the woofer I've demand the technical data on the archive of the brand. It's not really compete but I have the necessary to calculate the volume on WinIsd. I know that in the future I need a mic ( UMC8000 or one at 100$ really well knows ( I forgot the reference )).
Why did you choose 9 kHz as the crossover frequency? That is high for a two-way design.
Yes I know, my dad ( I'm 17 french cabinetmaker student ) have a friend that love the audio world. When we came in his house he let me try his system. A diy 22" sub in his table, and diy two way front speaker made with a 8" fostex and ribbon tweeter. The crossover frequency was 10kHz! And it sound really good at my ears. And a normal crossover like 4k is in the frequency that ears heard perfectly so if the filter is not good, it not sound good ( yes like every bad filter, I know ).
Do you already have the woofer? If not, you might want to use a driver that is specifically configured to play up to at least 10 kHz. A full range driver may work well.
The woofer taht i choose is a Davis 165MRP bi-cone. it as full frequancy range and it's the guy who have the system who recommended it to me. He love it, he have a good dynamics and a good flat response. I dont want to go lower than 70hz ( already have a sub ) so the bass under 90/80hz of the woofer is correct for me.
I think a lot of people would dispute this, as 1) measurements in the cabinet tend to change vs. specs which are typically for IB (I think?), 2) tolerances and inter-sample variation tend to be large for speaker drivers.
Yes I know, I need to buy a little bit different composant that I find on my calcul to test and choose the best result at my ears. The " active method " is to expensive for me. I need an active filter and amp for the active speaker. And my amp don't have pre-amp out ...I think a lot of people would dispute this, as 1) measurements in the cabinet tend to change vs. specs which are typically for IB (I think?), 2) tolerances and inter-sample variation tend to be large for speaker drivers.
So I think doing impedance and mic measurements in the cabinet are considered important for getting a really good result from the crossover.
@Charvel not sure if this fits the budget, but crossovers can also be done digitally or with active analog components, many people do crossovers with MiniDSP boxes, which allow you to tweak as much as you want with no soldering
