I’m currently using a Yamaha 3060 aventage receiver, paradigm 200 B bookshelves, paradigm 600 C Center speaker and the v12 paradigm subwoofer. I want to upgrade my subwoofer and I am not sure what to get. ChatGPT and Google pretty much confuse me with all their text back talk. I was looking at the defiance X 15 by paradigm, but they said for the money I could get a better sub from another. The only thing the two Ai’s did was tell me that I should probably get something besides another paradigm subwoofer. Any info would be awesome. My room is roughly 15 x 18 but it’s open ended on one side as it goes into the kitchen. I sit about 9 to 13 feet away from the TV depending on where I’m at on the couch.
