Hi all, I have a pair of ~20 year old KLF-20s. I've been reading about people upgrading their crossovers to Crites and/or upgrading their tweeters to titanium. Is there a consensus as to which of these two mods will have the more significant improvement in sound quality? Thanks!

Hi all, I am brand new to this forum. I have a pair of ~15 year old KLF-20s. I love(d) these speakers...still mostly do except for one issue. The last year or so, I am picking up a significant rattle from one of the speakers, mostly during loud scenes in movies, etc. I have done some reading and it seems like there is a "well known issue" with the cabinets and the glue coming apart or something? I have heard of several people "fixing" theirs. I'm hoping someone can point me to a detailed procedure with pictures and/or video of how to do this. I am very nervous that if I try to open these up I'll end up doing more damage and I can't afford to buy new ones! Any help would be greatly appreciated!
