Mods for Avantgarde speakers

I have Cardas Golden Ref. power cords on my subs (as part of the 3.2 package). A while back a friend brought over a pair of TG Audio PC's and they offered a nice improvement - bass seemed tighter and a bit deeper.

I've been looking for a pair for sale since then, admittedly not too hard, and wonder if anyone else has experience with other PC's on the subs?

I'm using DCCA power cords- much better, that stock.

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!!
happy tweaking

Duomike,
I'll try the solder. I never did think the way the wire was fastened was adequate. Did you find moving the tweeter back you were able to sit closer. What is your seating distance. How did you support the tweeter.

I recommend reading "Get Better Sound" by Jim Smith. I just finishing reading this book and very much enjoyed it. Jim Smith was the original distributor for Avantgarde USA. He has probably set up more Avantgarde speakers than anyone. His would be another good opinion on proper time alignment of the tweeter.
