If you need steep slopes you will be better off with high order LR 'shapes'. Try to avoid brickwall filters as these will add additional constraints for complementarity (same number of taps, etc.).

Always use complementary slopes for your crossed-over drivers (ie LR of identical slopes on both sides, 'reject high' on both sides, 'reject low' on both sides, etc.). For good measure, use the main volume attenuator in the 'general' tab and make sure your correction does not exceed 0dB (amplitude offsets will have to be dealt with at some other place, for example in the crossover engine or in the amplifier.).

Check the correction curve with the measurement bypassed to make sure it does not get too high in amplitude (for example if the target high-pass filter is much lower or with a shallower slope than the natural one.).

Apply the desired linear-phase high-pass and low-pass filters, and make sure you do not exceed the capabilities of the driver (excursion down low, breakups up high, directivity, etc.).

Do not operate your driver with this kind of correction of course: this is only a temporary state! If you don't then adjust your 'compensate' settings, and also play with the 'time offset' option in the measurement tab. at that point you should have a linear amplitude and phase (in the pass band and around, depending on your noise floor). Use the 'compensate' mode in the minimum-phase filters tab to flatten the natural high-pass and low-pass of your driver by trial and error (you need a measurement with a low noise floor, as it will quickly realize when playing with that feature.). For each driver (with several measurement per driver, as discussed above), use minium-phase EQ to get the amplitude reasonably flat within the pass band (the more you can trust your measurement(s), the more precise you can go, hence the reasonably) So here is how you can do it (among many other possible scenarios) : Many results for simulations done in ABEC show how powerful this tool is for the DIY loudspeaker developer.ĭon't let the amount of information overwhelm you A short introduction to AxiDriver with an example simulation for a horn - file attached.

Included in the program is a software for displaying the simulation results VACS and a program for simulating rotationally symmetric drivers, wave guides and horns in an infinite baffle AxiDriver. In order to create reliable simulations with the program, however, you should expect weeks or months of self-study. In the free version projects cannot be saved, but for DIY the use of this version is sufficient. Unfortunately the current version is only available in German.įor high quality simulations of complete loudspeakers ABEC is suitable (complete docs are in English). With it you can easily simulate your own (Visaton) loudspeakers. Most Visaton loudspeaker measurements in infinite baffle are already included in the program. It also comes with some very helpful tools.Įven with this tool it is possible to do simple simulations for loudspeaker baffle.Ī tool for crossover development with simple simulation of complete loudspeaker cabinets supported by the loudspeaker manufacturer Visaton is Boxsim 2.0. One of the best (and free) tools for passive and active loudspeaker crossover development is VituixCAD.
