Replace the new MDF wood cover for the main board of the Boombox 3 speaker

[caphe]

I have a JBL Boombox 3 bluetooth speaker with a damaged case, I want to make a new case with MDF wood. I don't know the technical specifications for the new case to fit the JBL Boombox 3 speaker motherboard with a 5.25 inch subwoofer and a 5.12 inch resonance membrane. This is the parameter I measured with a ruler.
Someone who understands the main board of this Boombox 3 speaker, please tell me what is the frequency range of the DSP of the subwoofer, midrange, treble channels and help me with the specifications of a new MDF wood case with a 5.25 inch subwoofer and a 5.12 inch resonance membrane and the DSP on this motherboard.
Please help me, thank you very much!

If I were trying to solve this problem, I would build a similar size enclosure with the cutouts for all the drivers based on photographs in https://www.google.com/search?q=jbl+boombox+3+teardown. From that you would need to include any ports. It might be easier to repair the case with auto body materials.

If you still have the case you should measure it and determine the total enclosed volume of the case. If you don't have it, do your best to estimate it from videos/ photos. Make sure to account for the separate enclosures for the mid / tweeter. It doesn't look like there is a port so that simplifies it a lot. If you know the enclosed volume you just need to make sure your new box has the same volume and the speaker should work about the same. You don't need to know the frequency ranges or DSP settings to do this.
