Hi, just joined and first post here, thank you for accepting me. I used to have an older AV setup and then lost interest/access due to my kids taking over my home theater room! I just set up a new system, buying a maranta AV controller 7705, new Samsung 75' TV, Sony 8000M2 BR player and using my older speakers etc. I have a MX 5000thx Mk11 and a Velodyne SPL Series 11 subwoofers. Am I setting up a problem using these 2 subs? Any advice on setting up etc.? I don't want to buy anything new if I can help it. I'm in a 7.2.4 system. TIA. John
