After testing and wearing them in, I can definitely recommend these speakers! Had Z4s to compare them with. Listened to a variety of music (IDM/glitch, post-rock, rock, indie, dubstep, classical-influenced) and played a game of Starcraft 2. Will do a more in-depth review in a new thread soon.
All in all, I was sad going back to my Z4s. Music experience is much better on the Krators, without a doubt. Will be ordering mine on Monday.
I'll start with the negatives:
-Left speaker's mid driver did not work properly out of the box. After re-plugging it in, it was 100%. I felt a bit sceptical at that point!
-Volume controls (as well as bass and treble) on the side of the right speaker. A remote would have been great (so used to having one). One would have to use software/keyboard/etc. volume controls unless they lean forward to adjust the volume on the speaker.
-The 4" sub drivers do not produce deep bass that some genres would demand, especially DnB, dubstep ,hip-hop etc., although mostly the bass is above acceptable. The difference in longer bass notes was especially noticeable, although I am used to my boomy Logitech Z4 sub which handles low, long bass much better (due to being 2.1 and the sub being a few inches bigger I guess).
-Driver finishes could be better. Of course, they are no KRK Rockits though.
-Cabling could be a bit thicker.
-No speaker covers (black ones would be nice) although the look did grow on me.
-Regarding warranty, the info seemed to made it clear that speakers are normally repaired instead of swapped-out. Not sure how accurate that is, but I know that Logitech would swap out with no questions asked.
And the positives:
-Music listening is a lot better than 2.1. You really notice the difference that the mid drivers make, the fuller sound. I heard sounds and melodies that I had not heard before on the Z4s.
-Excellent for Starcraft 2 and games that aren't too bass-heavy. I really enjoyed the sounds and directional accuracy in the game I played. FPSes and other bassy games would be a lot more immersive with 2.1. For games that don't need too much bass, Then I think these would be fantastic.
-Very accurate tweeters and treble can be adjusted. I kept it at half-way.
-Bass can be adjusted, also kept at half-way.
-Well built and they feel solid.
-RCA inputs.
-Line in on side of right speaker for iPods etc.
-Good packaging.
