Hi everyone please help me with something. I have recently purchased a Paradigm servo 15, it came with the x-30 control box but no instrutions. I have always plugged subs in via a speaker line input so I have deep bass all of the time aswell as a sudden blast on explosions etc. I think looking at this sub that it only plugs via the LFE output from my receiver whiich does not suit me much. Reading the web site it looks like I need a x-20 box to plug it in how I want to. The sub arrived damaged and is going back on Monday, I can choose either a refund or replacement when they get more stock, so I have the weekend to play around and see if I like it. Any advise on how to plug it in will be greatly welcomed as it looks a beast and I would rather replace it than look for something else. I know on the reviews I read that people gave an opinion on how it sounded with music. Surely you would have to plug it in via speaker line inputs to hear music through it? At the moment its plugged directly from the receiver to the sub, and you will think I am mad but it seems to lack authority like that. Thanks, Neil.
