I use them for 3 ½ years.
These speakers dveloppent power monster (600w/enceinte), with its enjoyable trs.
RSID the problem especially in their weight! (Fifty pounds pice).
They give her an equilibrated making pretty good instruments of any kind as well as voice.
I prfre to faade Systm good in the genre or HK DAPaudio, which for the same weight over Systm (pregnant + feet!) Are more flexible and better make the treble ( some LGERS on K6).
For cons, I now use exclusively in return, and the man!
This is luxury!
If I had to buy return is the K6 that I would!
