sdrsdrsdr, the avantgarde construction is a bit flimsy for speakers so expensive. the new g2 series looks more solid. no doubt any damping helps the sound. before you change the internal wire just make the effort to solder all internal connections, also on the driver side. makes a nice improvement in clarity and costs basically nothing. if you can try the harmonix rf 999 cones. once one of my audio buddies came to me place and asked me to remove the cones. he was shocked at the differences and said this is crazy and I'm not using the avantgarde subs at all. If you can try to find a way to put the tweeter 15-20 cm back for time alignment. this makes a huge difference!!
