KRKV4 Series 4 4" 2-Way Powered Studio Reference Monitor, Black

They hiss - it's a feature, not a defect, I found a KRK sound engineer arguing online. It's clearly audible from a metre away, and all they need to hiss is to be powered on. It's not a question of the cables of audio interface. I experimented with different settings, cables, and sockets. Good sound otherwise.

I love those KRK V6 monitors. They sound fantastic, the response curve is flat enough, and the adjustments on the back of the speakers do what I expect them to, and they're powered speakers which is even better. They're not small by any means, but they sit perfectly on speaker stands in my home studio. I would absolutely buy again (in fact, I have, this is my second pair - one pair for the recording studio and another pair at home.)

Sound quality is the best I've found at that size. Almost as good as the JBL 305 or 308, but at a more compact 4" size. Much better than the Presonus Eris 4.5 (which sound tonally correct but boxy and bright to me). Vocals and detail are excellent (albeit the JBL 305 has the best vocals I've ever heard) without sibilance (a major improvement over the annoyngly sibilant iLoud and Genelec 8010A). There is some mild hiss because the KRK use class D amplifiers. The hiss can be lowered by flipping the -10 dB switch to + 4 dB at the back of the speaker. It can be eliminted by using a XLR source. I used a 3.5 mm stereo (from my PC) to dual XLR cable, and got an annoying buzz when my GPU was in use. I got a Fiio USB DAC with a balanced out, and plugged that in the XLR inputs, and the buzz was gone. What I really enjoy about the KRK is that they are not harsh or fatiguing (a problem with most 4" studio monitors on the market). They reproduce high frequencies but do not exagerate them. I returned the Genelec 8010A, iLoud Micro Monitors, JBL 104 and Presonus Eris 4.5 because they had harsh and fatiguing treble. Piano may have been 100% tonally correct on the Genelec, but I could not stand the harshness and sibilance. I find the KRK much better overall and my search is over - I am quite happy with this pair of KRK V4S4. Electricity consumption is about 7 watts per speaker at 50% volume.PS: The first speaker I got had port noise / resonance when playing some low frequencies. It is not audible in most music, but when playing piano music with low notes (such as "In the pines" by Brad Jacobsen or "Probleme de emotion" by Igorr) this resonant noise was very audible and annoying. I ordered a replacement and it does not have this issue.

The minute you turn them on, there is an audible hissing sound. Even without audio cables plugged in and low volume. Sent back to Amazon.

Accurate and high quality sound. durable and well made product. Descent bass response despite what other's say, and i'm using this for hip hop and electronic dance music in my home studio with no additional sub. Would highly recommend over the regular KRK 6" model which I purchased originally then returned for these bad boys.
