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.

Montert N v9

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

Montert N v11

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..

@mundsen I'm excited as well. I can't wait to hear your impressions. Especially with that passive radiator

@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 🙂
