Cambridge Soundworks model 12 mod

I hope this is the spot to find a tweak. I've had the ultimate travel model 12's since about '98 and have done a lot of things to keep them tip top over the years. I've been a roadie with rock and roll and theater since the late 90's and this was the system you wanted on the plane with you before the whole powered monitor movement. I'll just say that these speakers probably have more frequent flyer miles than some junior flight attendants. They've been in over 20 countries.

My question for anybody that has had these is that I want to change out the speaker terminals on the amp. Anybody done it? I know it'll require soldering, I'm just curious if anyone has tried this. Ideas?

Thanks guys.
