Hi Everyone!
As you all know, the process of building a multi-way speaker when you've never done it before seems like a lot to learn, and it is. There are many different measurements and analysis that must come together correctly. We often answer these questions ad-hoc but I always wanted to put together an example that shows most of these steps done and completed into a type of free experimental workbench that lets new DIY builders "get it" at once.
I am also a huge fan of XSim, OmniMic and DATS. I'd like to offer my own contribution in the hope that it helps newbies play with all the "pieces" needed to simulate a crossover. I am particularly astonished at how much working with XSim can help a newbie get a visceral feel for crossover design, and learn how to answer their own questions.
My goal is not to encourage building of this speaker, but to let a new person see all the pieces together and working. To talk about different problems and try them here.
For instance, a recent question in the Multi-Way forums was how to add a second woofer and how that would impact the impedance and crossover. That's the kind of experimental lab work I hope to encourage here. Also, for instance, seeing how distance changes affect crossover and phase design.
I encourage, and hope the experts will contribute and enhance this thread with their own examples if they'd like.
So here is my humble offering, the XSim for the publicly available and discussed LM-1 "True Bookshelf" speaker.
Best,
Erik

To add to the workbench, I am providing my own simulation of the current A26 kit. I'm afraid it's pretty rough, but should be a good learning tool. 🙂
Of course, the most excellent XSim by Bill Waslo is available here:

If anyone wants to actually build the LM-1 the build thread with more information is over here:
http://www.diyaudio.com/forums/multi-way/291438-lm-1-diy-speaker-available.html
The A26 kit is available here:
https://www.madisoundspeakerstore.c...6-10-2-way-kit-pair-based-on-the-classic-a25/
But please take any actual build questions over to the Mult-Way forum. This thread is for learning about crossover design, and posting experiments.
