Hi everyone,
Don't know if it has been mentioned before,but when I soldered all the LF connections(up to the speakers) in my RF-7's ,the bottom end definitely improved and thus reducing the relatively high amount of high freq's.(Which didn't bother me because I bi-amp them. but it might help someone else)
There are some poor connections inside this (and most-I guess) speaker .Connections you wouldn't dare use at the end of your amp-....so why accept them inside your speaker?
