Hello forum,
given all the available DIY boards and modules, it should be possible and not overlay complicated to build a DIY speaker that's pretty much fully digital. With that I mean: You connect it to a computer and you're done.
Picking good options out of the vast selection is quite a challenge though.
Background about the speaker concepts I play around with: They are generated using Acourate software, they use digital crossovers and therefore need a dedicated signal line for every single channel. I'm currently planning a 4-way concept, so we're talking 8 DAC channels and 8 amplifier channels.
Wondom seems to have a comprehensive selection of DAC boards, volume control boards and class D amps. Even DSP is available, but not necessary for my concept. For amps the choice is also massive, as already discussed here in other threads.
With amplifier modules and DAC boards integrated into the speakers, what's a good way to get the digital signal from the head unit (PC) to the speaker? I'd rather not run some 3-5 m long USB connections with their badly designed plugs. How about I2S? (https://www.boomaudio.de/wondom-s/pdif-i2s-audio-signal-konverter) Or is a simple SPDIF connection easier to handle - given that I equip the PC with a sound card that can supply enough outputs?
