Yes, I have 2 K10.2s. And for reference, I also have a Bose L1 Series 2 system. I bought the K10.2s on a recommendation from a fellow keyboardist and simply because the L1 didn't do the job at a recent gig. The gig was a long rectangular room with about 150-200 people. Very noisy people, I might add as it is a pizza and beer place that features music.
The first time I played this gig I used the Bose. Sitting behind us, we had it so loud that we were almost in pain. (Ear protection at home. Yea, I know.......) While it sounded good, it had a real problem in covering the crowd as the bandstand was recessed with walls at one end of the room. Most of the energy bounced around us, the musicians.
Got my K10.2s a few days before the next time we played the same gig and what a difference. Everyone could hear, and we didn't have to use ear protection. (Yes, I did bring this time.)
The sound was great and an easy setup. Plenty loud and I did not hear any harshness from keys, bass, vocals, and guitar. I used an Allen Heath mixer for this duo gig. I have since added a QSC TouchMix 8 and although expensive, it is great.
Everyone will, of course, have their own opinion. I have used EV for years, and also like the Yamahas, but I've moved to the QSCs. There is no doubt that the RCFs are great, but for the cost, I'm happy with the 10.2s - they have a great sound to cost ratio. BTW, they have an amazing amount of bass. And the fans are very quiet.
Looks like time to sell the Bose.
