Dinas Boombox with passive radiator like the Voxel Sub?
Some progress - started cutting the different parts - this is the rear side (only test assembled).
Next I`ll make holes for the speakers.. and start assemble/glue the frame
I plan to make the battery/power module and the amp module like cartridges that I can insert in each side chamber.
Do I need the dedicated enclosure for the RS100-4 elements when they are in separate sections from the sub like in my design?
I`m going to use the Dayton Audio LBB-5 5x26650 battery module - I get som more space if I do not have to make the separate "boxes" for the rs100
With "dedicated box" on the left side - without on the right side
@mundsen That depends how much air volume the side sections currently have. Building a small sealed box around mid/high drivers isnt just about isolating them from low frequency drivers, the size of said box affects the flatness of the mid/high drivers frequency response the same way that the overall box size affects the low drivers response.
RS100-4 would ideally be in a 0.0675 ft^3 (1.9L) closed box to acheive an ideal Qtc 0.707. If the current volume of the section is a lot bigger than that i would suggest boxing them in

If I make it like this, I get a 1.9L closed chamber for each RS100-4
+ I get separate chambers for the amplifier and battery modules
Then all 3 chambers should be optimal 🙂
Some progress 🙂
Next, I`m going to round the edges, sand..
I do consider beewax - ok?
Shoud I use some kind of "cabinet damping" material inside the chambers?
One step closer 🙂
I`m using this project to learn using my new router - learned the hard way when rounding the front panel edges and got some chipping - used some sparcle trying to fix it - the edges are smooth, but it takes the wax/oil in an other way than the brich plywood.
But I like it this way - gives a bit wear and tear look that I like 🙂
Tomorrow I`ll add a layer with clear wax/oil to get better protection
Learning by doing 🙂
Test installed the elements.. 🙂
Next I`ll have to make panels/mounts for the battery and amp modules..
@123toid Not tested yet - have to add wires and seal the sub chamber..
But soon - exited
@123toid do you use any kind of damping material in the different chambers?
First sound test - impressed
A lot more to do before it is ready - I have the wrong weight on the radiator - the RS100 have no rear panel yet, not tuned the amplifier at all...
This is fun 🙂
