There's no risk of me buying anything from him, question still remains, is he wrong or not?
In all fairness, I did ask here first and with a good reason bc I'm really buying this, but I have to know first how to do it.
I remember an answer from one member here on AH, I think his nick was Steve81 or Steven81 (i really liked that guy) he answered directly to saying it could be done via pre-out, but back then I knew I still don't have the money to buy so I didn't bother him with all the details.
So far, I understand that you can use pre-out/mains-in to add a DSP, but it just seemed to me that if a SVS sub has a DSP built in, I could also use this way to add the very sub. Take the signal from the integrated to the sub, manage bass and return the rest to be amplified in the amp section via mains-in and then to main speakers.
It was just my assumption that this would have to imply some slight delay. Now, if it's true that you can only add delay and not subtract delay, it seems possible.
Anyway I wrote to SVS. I'll see what they have to say.
