You guys have been going in circles on pk21. That is a very good kit indeed but there are two problems with it.
Firstly the speaker cable you get is of 10 meters.
Secondly you get the performance RCAs.
Now when we install comps, this speaker cable is not going to be enough, secondly the Elite RCAs from focal (ER5) are far more superior than this performance RCAs.
Thats why seniors haven't used this kit otherwise still its better for beginers.
Focal, Morel, Dyns, etc are top of the line sq brands but one thing is for sure that these all are allergic to stupidity.
