Great online speaker calculation tool

[elac310]

I've found today an excellent online tool to work on enclosure calculation

The great thing is that it simulates on frequency curves the impact of any change made to the parameters (not just the volume but also lign/filter resistance, vent length etc.) and as far as I can see, the results from simulations are extremely similar to what we measured with my systems.

The audiomates from the fullrange and subwoofer forum might be interested as well (the website has also a baffle step calculation tool and a so-called "advanced calculation" tool that takes into account many additional vent parameters.

By the way, does anyone know a similar freeware for acoustic speaker measures and crossover calculation (all-in-one system to avoid data import/export issues)?

Don't any number of programs do this, like WinISD?

As regards enclosure calculation, I prefer the tool I've mentioned over the online version of WinISD; it is more accurate and user friendly (no need to erase all the curves after a while etc.), and very convenient for a quick calculation or a check as regards suitability of a candidate woofer for a given standard enclosure (closed, BR, sub). The more sophisticated (downloadable) programmes of WinISD are of course more advanced and allow for many more options (passive cone etc. etc.).

If we are talking about acoustic measures and xover calc, I'm not sure the (downloadable) programmes of WinISD allow to do that. But I might have missed something.
