Dinas Boombox with passive radiator like the Voxel Sub?
My first plan was to start with the Voxel plans (have ordered the element and radiator and extend it to make a portable boombox - but it get a bit large if I only make extra "boxes" on each side for the full range elements.
Is it possible/hard to make plans for a boombox that uses the passive radiator for optimal quality?
I`m going to use the Arylic up2Stream 2.1 amp
This is my first idea - the sub section have the same dimension as the Voxel sub - only centered the elements. But it gets a bit large doing it this way
Something like this then - the bass section is the same as the voxel, but moved to front and rear
Separate chambers for the Dayton elements - I plan to install the amplifier and batteries here
Should I optimize the volume for the RS1004 elements or is this ok?
Nice design 👍, looks similar to my version of the Dinas Boombox, also regarding the use of the passive radiator and the Up2Stream Amp 2.1 board. I'm not a acoustics design expert but just for a rough orientation, here are the volumes of my boombox:
- total inner volume including the compartments for the RS100-4: ~13L
- total inner volume excluding the compartments for the RS100-4: ~10L
- inner volume for one compartment: ~1.0L
Do you already have an idea on where to place the controls of the Amp 2.1 board? Any plans for a custom control panel?
When your finshed with the build, I would be very interested to hear how you tuned the passive radiator and the EQ of the Amp 2.1 board. Good luck.
Same volume.. only moved the element to the opposite side of the passive radiator - So I`m going to tune it like in the Voxel instruction and start from there
Not decided what volume to use for the rs100 (not using them for the bass) - The dina boombox have only a small volume for them.
Not decided where to place the controls for the amp -but some kind of custom panel
+ I`m going to include lipo batteries, charger..:
|Dayton Audio LBB-5 5 x 26650 Lithium Battery Charger Board / Module
|Dayton Audio LBB-5EB Expansion Board
|Dayton Audio LBB-5CL Cable Package for LBB-5
I guess the amp in one side chamber and the charger and batteries in the other side
+ I`m going to use 18mm plates
My idea (for now)
This gives me two "boxes" for battery and amp installation
You don't need much volume for the rs100. I would stick with the same enclosure design and just add the passive radiator on the rear. If you keep the volumes all the same and follow the tuning instructions on the passive radiator, it should tune it perfectly. Just don't install the port (still keep the same outside dimensions though).
The sub section have the same inside dimension as in the Voxel Passive Radiator Subwoofer Plans. The volume for the rs100 almost the same as in the plans for the dinas boombox.
The "free space" in the sides is perfect for the amp and batteries.. - I do not have to install anything in the subwoofer section that may mess up the tuning.
