Hi guys, I'm quite a novice at this so please forgive me.
Currently I have a USB connection going to my A2+ Speakers and using the built in DAC. I then have a low level input from the Speakers to the Sub which I have set to about 75hz cutoff. This seems like a sub-optimal way of doing things. Am I right in thinking this is bad in terms of sound quality with the inevitable merging of frequencies from the A2+ and the Sub?
As far as I can tell my other options are:
1) Buy a an external DAC, run the cable directly to the Sub and use the high level feed and use the A2+ Speakers as satellites.
2) Buy a Sound Card and use the flex bass utility on the Xonar Audio Center to set the crossover frequency.
3) Buy an external DAC and use a splitter between the Sub and Speakers.
Not sure what would be the best, never had any experience with Subwoofers before so many thanks for any advice you can give!
