I was wondering about this 'crossing over' thing. I currently just send dac output to the amp. (Gustard x20 -> magtech) I spent a fair amount of time troubleshooting the USB output of the pc feeding the gustard. Finallly settled on a custom USB card driven by an external linear ps and the sound is good. Now adding a sub to this setup can be done at the speaker level or the line level.
1) I do not understand how adding a sub at the speaker level lightens Maggie 's load. It is a parallel electrical connection at the binding posts so the Maggie sees no change in voltage or frequencies presented to her.
2) a line level connection through a Y connector presents the same issue
3) a preamp w bass management and eq as well (emotiva?) seems the only way to lighten Maggie 's load. But I am concerned about adding another component in the chain with its a/d conversion, digital processing, and then d/a conversion. But I guess if I have a pc as the source I can just run Dirac on it for the eq. Which brings me back to the eq method. I am leaning towards rhythmic subs with the peq amp option.
