So I'm thinking of getting the Swans M10 and I would want to replace the included midwoofer with a separate powered sub, specifically a Dayton Audio SUB-1200. Would it be possible to just not use the midwoofer, and add in the powered sub in place of where the midwoofer would be? Or would I need to connect it directly to the source as a standalone device, instead of adding it to the speaker chain?
