If the placement options are possible in your room, I would split the 6 subs into 3 sets of equidistant pairs and use 3 (y-split) MiniDSP outputs, that would probably work well.
Thanks for responding here Alan. I had actually given some thought to running the 2 subs behind the couch from a single out on the miniDSP using a splitter, but the other 4 subs are all different distances from the MLP (approx. 12.3', 11', 10', and 6.2') so it made more sense to me to use the miniDSP for those 4 subs. The other reason I went the way I did was because I would have been one 'out port' short of being able to hook all 6 up unless I paired up another 2 subs as you suggested. I suppose the 2 subs that are 10' and 11' from the MLP are pretty similar in distance and could maybe be paired up with a splitter, i'll experiment and see what kind of results I get.
My reasoning for doing it all the way that I did was that once i'm all done with getting my sub alignment done in the miniDSP and I re-run Audyssey, it would set the distance for the 'virtual' sub (for the 4 subs the miniDSP is running) as it should, but by utilizing the 2nd sub out on the Marantz I thought that it would allow me to set the distances more accurately for those 2 near-field subs.
For a little more context, my room shape is not ideal so I used the Earl Geddes sub placement method to locate all of my subs, and I figured that 6 subs would be plenty to mediate any potential room mode issues. Sub 1 is located midway up on the front wall centerpoint, sub 2 is located in the front left corner, sub 3 is to the left of the couch and maybe 1 foot further back, 4 and 5 are centered behind the couch with 24 inches between them, and 6 is on the back wall (about 4 feet offset from the wall centerpoint) in a straight line from the 2 behind the couch.
I had to open this new AVS acct. because I lost the PW for my previous one (my email had changed since opening it so I couldn't just request a new PW). Once I have some more posts under my belt and my AVS Forum access allows me to, i'll be sure to include some pictures of the room in my next post for people to reference.
