I have been playing with these subs both in front of the couch on the side walls pointing in and also behind the couch with the back port pointing the couch to also keep my kids off the knobs on the amp. Seems with them in the front there is more spl but in the back it does add some cool tactile feel to the couch that the shakers don’t add. It needs to be tuned and stuff. But what I am thinking is doing sub out 1 to my nx6000d to run the Marty’s. Then sub out 2 will split and run the shakers and then also to the f12 subs behind the couch. Then I can do Audyssey and it can set the two sets of subs independent and get distances right. Can anyone give me any tips on what I should do? I am just learning and want to get it setup the best I can. Thanks.
