Xsim - configuring the plot window

By default, the Xsim plot area looks like this. It needs a few more things before it's ready to use.

Here is an example of a useful configuration. I've switched on each driver response and included their phase. The system response (the combined response) has been set as not to overshadow the other traces. I also like to turn off system phase to declutter.

There are 3 plots from the curves menu for a 2-way.. the woofer (S2), the tweeter (S1) and the combined response (System). You can also select their phase plot here..

(By the way, viewing the (driver only) plot shows you the response without the crossover. This can help, for example, seeing where you've boosted the response and whether you can get more sensitivity in general.)

Set the plot area size using these controls.

1. The frequency span in Xsim (the X-axis) usually looks best at either 10Hz-20kHz or 100Hz-20kHz, but it depends on your needs.

2. The vertical step size is useful at 3dB, but again it depends. 5dB might be better when you begin a crossover, or less when finetuning.

3. Ordinarily, set the vertical center so that there is a comfortable space, say 6dB or so above the main level, once your crossover starts to develop a level.. and 20-30 dB below it.

When showing plots with a question on the forum, please indicate whether they are measured or you are using factory plots since this helps others make allowances for the differences. If factory, have you simulated baffle step information on to it? If measured, have you gated?
