I recently acquired Reference Model Two~Two's. I was talking to one of the KEF engineers about them and he said they recommended getting the bass units re-foamed after 15 years, so it's worth getting yours done if they've not been already. He also said that the Models were his all time favourite KEFs, which was nice
Edit: I'm hearing that perhaps the Models Three and Four don't use foam on the woofers so it's probably just mine about due for it.
My Model 3's have rubber surrounds,as do my early-run 104/2's.My later bi-wire 104/2's had foam,which had completely rotted away and had to be replaced.
Not difficult work if you are mechanically inclined,just time consuming.How is parts availability?I've read that finding replacement tweeters can be a real issue.
My initial observations with the 3's were a vastly improved low end and a sweet spot that's just huge.I really believe that the 2's and 3's are the best choices in this range.
I had always wanted the Model 4's,but after auditioning the 3's,I quickly came to the realization that unless I moved into a castle or a small auditorium,the 3's were more than adequate for the size of my listening room.
