I just got a pair of the same big Kenwoods this week. They came with a Sansui 9090. I have them hooked up in the garage now, listened to them all day. They are not bad, I needed the loudness switch on at low volumes, and at louder volumes I switched it off and used an equalizer. I would compare them to many of the big speakers of the day, (Sansui, Pioneer)too many drivers in the box. That being said, they all are fine in the right application. I am an old geezer and prefer the more mellow, neutral sounding speakers now. My kids LOVE them big honkers, they sound so much better than their cell phones they use to rock out on.
