Hello everyone\n\nI am looking to upgrade my 30 year old Velodyne 1215x sub to Paradigm x12 or svs 2000 pro. My room is 28x15x7.5. My wife will not allow a 15 inch sub and due to constraints of sharing this open space with my kids 2 subs is not feasible at this time. Any recommendations would be greatly appreciated. Looking to use The sub for mostly movies. Also looking for a hard hitting clean sounding sub. Lastly, has subwoofer technology evolved enough that I am even going to notice a difference from my old Velodyne with a 12 forward firing woofer and a 15 floor passive radiator with 240w A\/B amp? \n\nThank you your input.
