Alpha Core Goertz

@pops Thiels are a pain (I had a pair once).  I would attach the Zobels to the amp end if using Thiels.

@ozzy I soldered ring terminals to my Zobels to make attaching them a breeze.  You could also use spades.  Easy peasy.  These don't have to be expensive audiophile spades.

I am under the impression that Zobels are required with some amps to prevent them from oscillating and overheating.  I installed my Zobels and played the system all day, periodically measuring the amplifier's heatsink temperatures and recording the results.  I then removed the Zobels and did the same thing.  There was no difference in temps, so I concluded that they were not necessary for my particular amplifier. 

This thread does not match my experience.  I ordered a set of Zobels from them a year or two ago and it was no problem at all.

@ozzy - I have MI 3s and don’t think they have Zobels built in. I don’t think it’s even an option, but maybe the previous owner of yours had them custom made. Who knows.

I tried Zobels on the bass side of my bi-amped system and noticed no difference at all, so I removed them.
