Turning 40 year old speakers into PoE-powered Airplay speakers

The beovox-poe project is an 80W PoE-PD PCB and panel mount for powering a HiFiBerry Beocreate 4 channel amplifier for upcycling B&O BeoVox CX50 and CX100 speakers.

The end result

• PoE-powered
• Data passthrough for quasi gigabit Ethernet connection to Raspberry Pi
• Play audio over AirPlay, Bluetooth, etc.
• They look and sound awesome

How to build it

PCB

I designed the PCB to be ordered from JLCPCB. You should be able to get 2-5 boards fabricated and assembled for about $100 (not including the parts you will need to hand solder, see below).

1. Upload the zipped Gerber file "beovox-poe-mfg-rev2.zip" to JLCPCB
2. Select the silkscreen color you want. Green is usually the cheapest and fastest.
3. Select PCB Assembly and "Assemble top side". You can do both sides if you want them to solder on the threaded standoffs (MP1, MP2, MP3, MP4) but it will cost more.
4. Click NEXT
5. Upload BOM. pcb-files/Project Outputs for beovox-poe/BOM/Bill of Materials-beovox-poe(assembly).csv
