I know this is not a forum about modifications but I have been playing with the krk for a while and I have to say that from my perspective they are not bad but, the cost reduction yes
If you like to take things apart you can do 3 of them on the monitors to improve them a little:
1.- You can increase the power of the amplifier a little by modifying the power supply, this is noticeable at higher volumes
2.- Between the woofer and the wall of the tuning tube there is no absorbent material and you can add a little to reduce the resonances of the woofer
3.-You can open the tweeter and change the absorbent material for a better one and fill the small non-resonant cavity, I used cotton
Results: I don’t know how to explain the difference, I just know that I felt it in my skin, the differences are subtle but very present
Is it worth it? I think so, the delicate sounds of music never sound the same again
