Its amazing how fast you can pull these changes together.

Thank you.

I agree. The power dissipation display is excellent.

As I've completed my crossover work for now (except for a little value tweaking over long term listening) I am only opening the program from time to time but it seems that every time I do there is an update and new features!

Someone may wonder how total output volt-ampere (VA) and total output real power (W) are calculated with fully active or multi-amplified or hybrid multi-way with two or more power amplifiers where phase angle of impedance/current doesn’t effect to other ways because ways are “isolated” by amplifiers.
Output power of passive system with common power amplifier is simply P=U^2/Z. Volt-ampere (VA) is magnitude, and real power (W) is real part of the magnitude. This will work also for individual active ways, but not for total output.

Way is handled as an active with dedicated power amplifier if there is at least one enabled active block. Output volt-ampere (VA) of this group is sum of volt-amperes of all active ways, and output real power (W) is sum of real powers.
Total output power of multi-amplified passive system can be simulated by adding useless active block (e.g. PEQ with gain=0 dB) to ways having dedicated amplifier.

If system has both active ways with dedicated amplifiers and passive ways with common amplifier, total output VA is sum of volt-amperes of passive and active groups, and total output W is sum of real powers of passive and active groups.

All this mess only for combining total output power into two curves with some logical manner.

Thanks for Kimmosto's great simulator.I have an additional suggestion for your software update.In the ENCLOSURE menu,the type of vent is circle by default.Vent of triangle or rectangle is possible to be added in the simulation process.It will be far better I reckon because sometimes I build some pro audio loudspeakers when I'm working on this simulation program.Thanks for adopting such a constructive idea.
Best Regards

^Area [cm2] option has already been added today in rev 1.1.31.0. That is easier with other shapes than circle.

Oh,thanks.How about vent velocity added?

^Velocity has been there from the beginning. Right click on the bottom right graph and select Show velocity.

This may have been asked and answered but here it is: the "gain" and "delay" should, IMO, switch the respective functions (with some data entered) on and off when the boxes are checked/unchecked. However they seem to be on always? The two functions below them (invert and enabled) however do react to the box checking.
Thanks.

^This was answered last time 1st March 2018, 06:22 AM. Function of gain and delay checkboxes is explained in both tooltip and manual.

First off, VituixCAD is simply a brilliant piece of software. My hats off to you.

Any chance the 15 filter block limit can be either removed or increased? I'm doing DSP work and trying to get really accurate response curves, and I would need more than 15. Really accurate driver correction alone needs more than 15. Then I need filters to optimize for the off axis response.

Thanks

P.S. Is there a way to donate? VituixCAD is really awesome!
