These are decent speakers nothing more than that, i have 4 of them hooked up to JBL GTO-5355 amp pushing 60W to each one. For the money they are worth it, have decent range, can play quite loud, but highs distort at higher volume (by higher volume i mean as loud you would not listen to it for more then 5 minutes). Also highs are noticable not bright enough but mids have just right kick to it. Lows are very good for money you pay, but have to be filtered below 80Hz if you want to be able to crank up the volume loud. Overall these are a good pair of speakers to drive around with and enjoy music, but sooner or later you would feel they have to be replaced with some better components. I myself am looking right now at either Focal Access comps or Morel Tempo comps to replace KS68s. Though they sound good, just not good enough for me.
