using ESS SAbre DAC for subwoofers is a bit overkill…

for sure it does not have ESS high quality DAC…
or you can also use a USB to toslink adapter, feed the output signal to a toslink splitter having 2 toslink outputs, then converting each toslink into rca to feed 2 TB at the end !
check also this kind of solution : https://www.minidsp.com/images/documents/Product%20Brief-MiniDIGI.pdf which uses a DSP you could program for the crossover function (and eventually eq & all)
EDIT:
you can also use a miniDSP nanodigi, it has one usb input, has 4 i2S outputs, is programmable, and you can connect up to 4 toneboards to it

Hello again!
I am still waiting for a “how to” connect three toneboards for a multi channel setup.
Is this false advertising from @Gouwa?
I have been waiting a long time for a answer…
In the advertisement I was promised stacking…
Right now I have two boards out of a planned setup made out of three boards. But I cant get the master/slave to work.
How do I connect three boards(or four) for a six, eight channel setup with master/slave/slave /slave configuration? And ofc in sync and no virtual thingies!
I am very annoyed because I feel misdirected from the advertisement. This is NOT fun!
Sincerely from a
Angry customer
