Can you post a close up of your crossover and list all of your upgrades.
Sure thing - here's a recent pic of the now-crazy amount of copper I have in the Super 7s:
Wiring is all VH Audio UP-OCC foamed teflon hookup wire. My previous reference wire was the Neotech UP-OCC w/solid teflon. The VH stuff is decisively better, IME.
Tweeter 10uf cap is Jupiter copper now, midrange 15uf is Jupiter copper now, the inductors are all Jantzen copper film and wax dielectric, the resistor is a copper Path Audio.
The only non-copper parts are the film caps I used to replace the 56uF Erse cap that was originally in there. I would love to put copper there to but that's horribly expensive and I'm not sure it would be a huge improvement since it's not directly in the signal path. Maybe if I win the lottery one day, we'll find out....
