So I received these speakers from my father and have been playing with them for a while. I decided well these aren't the best speakers in the world so lets hopefully make them a bit better. The original woofers were both toast so I replaced them with a Dayton Audio DS270-8. As I was looking into the cabinet I noticed literally nothing in these things just an empty shell. I figured what the hell lets put something in this cabinet. So I lined one of the cabinets with some jute (left side, back right side. leaving top and bottom uncovered). It's 3/4" thick jute and in all honesty it sounds worse. The highs and mids are just more loud and shrill. I don't fully understand it. These speakers never sounded amazing in the beginning but I didn't expect them to sound worse. So my question is what can I do to make these sound better. If it's not worth the investment are the cabinets worth keeping and swapping different parts into or am I better off building my own.
