I had just 8 "to reproduce good bass without using a subwoofer. KRK And in that I found the best value for money.
Comprehensive connectivity, they have the XLR, Jack, and even the RCA.
I use them only for the mixing (vinyl).


SOUNDS

Light "beautification" of the bass.
Good dynamic tweeters give precise treble.
Attention, a little noise is heard when powering up. Strange but perfectly normal according to the statements of other buyers.
Power level, it moves! And I can tell you that I am far from having tested everything they had in the belly

OVERALL OPINION

I use them for 6 months and have been seduced from the first days.
I had the opportunity to listen to M-Audio BX8 Deluxe, whose membrane seemed fast, too fast, move relative to KRK. Power level and fidelity at high volumes, the KRK were much better.
Other comparative listening, came from the Yamaha HS80. Restitution also good, but the KRK corresponded better to my style of music (electro, techno ,...). It must be said that the KRK coat well as I like the bass. Yamaha bcp that were more "flat"

Excellent value for money, on sale to 499 € in Belgium)
