This is homemade designed speaker box, popular today as boombox. It has 2 LOW, MID (Monitor Audio) and 1 HIGH speaker. Amplifier is 25W with bluetooth on it (Ebay, Chinese crap) which I will replace with my D class Amplifier (TPA3116d2) I posted earlier.
For LOW and HIGH speakers - passive crossover was used
For power supply I use 12V /12Ah Lead Acid Battery with charger implemented from old Laptop charger
Running time with full charged battery is about 24 hour constant playing.
AC plug and 2x 5V USB connectors are on the back side for charging MP3,Smartphone etc.
Design was made in SolidWorks 2016, files will be available on request.
