3D Printed 2.1 Isobaric Bluetooth Speaker

[Lanssssoooy]

Hey guys. So I plan on doing another 3D Printed speaker but this time, as the title suggest. I will be doing 2.1(or 2) setup. 2 reasons for why I want to do isobaric. I want to keep the box small (using the 2 4" daytons will increase the box size which I don't want to do - I want to keep the speaker handy or the ability to be carried and put almost anywhere that I want.) and 2nd is that I want more bass from a 4" daytons nd105. So can anybody give me tips on how I can utilize everything properly. Suggested box size, thickness of the 3d printed housing (I used 5.2mm on my first build) passive radiator size or literally building tips of the whole system since I am fairly new to this DIY audio.

Parts:
Aiyima 2" 20w full range
Dayton ND105
DSP 2.1 from aliexpress (good reviews tho)
21700 batteries with BMS

Goal:
-Keep it fairly "small"
-With passive radiator so that it is less sensitive on placement in the room
-Harman Kardon sound quality(?)
-won't cost an arm and leg to build. ($200 max)

I think that is it? Please feel free to educate me. I am here to learn. Thank you so much!

An isobarik is probelmatic if the response reaches up into the midrange.

You won’t get more bass, just a smaller box.

Hey man, thank you for the response. That is why the nd109 will purely be a bass driver in this. The 2" Aiyima will be the mids - highs. Although please more input is much appreciated.
