PSpice like software to simulate passive crossover

[diypass]

i'm searching for a FREE and simple software like pspice to simulate passive crossover
thank you

Waslo's new xsim is free and simple. If you're not into .zma and .frd files, it defaults to a fixed 8 or 4 ohm driver impedance like most other simple xover software programs use. However, the zma and frd files yield much more accurate results.

i know it.
i need to simulate sapately the output of two drivers in series crossover type

Would LTSpice do the job for you?

 

[diypass]

is it free ?

 

[djoffe]

Yes...LTSpice is a free download:

http://ltspice.linear-tech.com/software/LTspiceIV.exe


The above link is for the windows version...

for other versions, just google LTSpice download

It's just a standard circuit simulator, but there's lots of people who know how to use it, and can help you if you get stuck.

thank you
is it also free software ?

I recently did a series 2-way AR-SXO type crossover using xsim. Drivers spl can be displayed separetly.
I've tried LtSpice. It ain't easy.

please let me know how
about this for example ?

In the upper right FR #1 chart, click on 'curves' and click on s1 and s2. each driver FR will appear separately like those shown below in red and green.

I don't see why you couldn't construct a schematic in xsim like the one you linked to in post #9.

 

[diypass]

i will try....

 

[diypass]

fantastic!!!
noew i don't need aof any simulatore
thank you

This approach is rather limited. You need to have acoustic and electrical measurements of the driver in the loudspeaker box for accurate modeling. In SPICE you can only model the TS equivalent circuit, which is accurate around the resonance region (e.g. Fb). This model does not take into account what happens at higher frequencies, both from the driver itself and the box edge diffraction (baffle step).

But if you insist, it is a fun exercise. Look up the equivalent circuit for a driver and utilize the published values to set R,C,L in the model.

 

[diypass]

yes, i have electrical and acoustic measurements

You can use AkAbak to simulate complete systems with passive or active crossovers, but the required learning curve discourages many people. Akabak

too complex
