Maxolini, Solidworks will be more useful for my marine craft projects, especially the mechanical on the water gokart and I had a good read of Blender, and it is very powerful, but I still don't know if it suits engineering. Something to be explored in the future. I don't feel that FreeCAD is in the position to be a solid Freeware alternative due to the developer's approach for the whole program. They need to get the various benches consistent before users would be interested in coming back with bugs and things. I would admit that I see the program as an already lost cause........still highly useful but not very serious
I am rather inclined to beat this program into a useful prototyping tool for the hobbyist by working within its set of limitations. By using it to design a number of production ready items, I have already found many of those limitations. The good part is, once the limits and bugs are found, what's left is still a highly usable environment. This project will be a good measure of its performance. Let's see if it can be used to completely design a product with all the part complexities drawn in. Keep in mind that FreeCAD is not too bad for designing a part, the difficulties arise with interactions with other parts as the model gets more complex
There is something to really like, though. Once a full product model is created in detail, it is very simple to pull off individual parts or even chop up parts to fit the working areas on the CNC or 3D printers. It's worth persisting with at a hobby level

Is it Art? Hey man, how do you feel about replacing the dual 6.5" Dyaton PR units with a single 8 or 10"?

Some thoughts at this stage. Eliminate the robot head look and hopefully increase performance at the same time by replacing the dual 6.5" passive radiators with a single 10" passive radiator. This will also allow more of the structure to be built with PVC foam core sandwich instead of bamboo. 10" is the max radiator size that will fit this structure, so why not build in max Sd and Xmax here. This basically eliminates one whole panel and replaces it with an engine mount. Another side benefit is that it can be placed on its side 
with the PR firing down. The SBA 10" PR with 17mm Xmax looks good. I will use that as a reference but will first run a DIY 10" PR with hexcel sandwich and butyl surrounds in a custom printed basket. I'll do this spider less but with dual roll surrounds. There is an existing thread I started on PR units and will update that thread with that drivers build. I hope knowing types of folks like @weltersys concur with this line of reasoning towards evolving this baby porch PA sub
