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

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.

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.)

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.

High quality build and great sound.

not obvious that you're only getting one.

They sound really good.My standard procedure when reviewing monitors is to throw a few favorite albums at them and see what happens. If they still sound good after that stage, then we look at adding some mics and making some noise. Occasionally, they don’t make it past that stage before they're unplugged and packed back up. No point in wasting time on something that makes good music sound bad.With the V4 and V8, I kept throwing material at them and they threw it right back in my face.At first, I wasn’t really sure if I was impressed or not. Running sine wave sweeps and verifying the response with a spectrum analyzer showed a slightly tailored sound. I was looking for flat response. The initial reaction involved some hesitation.The reality, however, was that the only thing affecting the response was my room. Switching between my other monitors revealed similar coloration. So I stand corrected. Pulling a response chart directly from KRK’s own tests confirmed my room’s bias. Hesitation eliminated.Each monitor has a full control panel on the rear with the expected XLR/TRS combo jack for an input, power switch that brings them to life with cool KRK lighted logos on the front, and system controls for ground lift, attenuation, standby and dimmer for the logo. The company has also added a precise and somewhat elaborate system of dip switches and notched EQ controls for tailoring the response to a particular room.Low-frequency response on the V4 was better than expected from something this small. It seems very similar to the Rokit 4 monitors I reviewed a while back. But something was definitely different.As I moved from the V4 to the V8, the low frequency was fuller. I expected that. Presence was good. Stereo imaging was good. The sweet spot was nice and wide. But that wasn’t what began gnawing at me.The thing that I couldn’t get past was the detail.Without exaggeration, I've probably listened to (The) Dark Side of the Moon on more than 100 different setups. The details that caught my attention included reverb tails, background noises and several other sounds that I'd never noticed before. It actually provoked me to dig deeper into the dungeon of curmudgeon rock to see what else I could find.One album that I pull out if monitors can get this far in my test process is Janis Ian’s Breaking Silence. (Don’t roll your eyes at me like that. I bet many of you old guys own a copy. Admit it and we can move on.)This is one I've listened to maybe 20 times all the way through before today. Now it's been on a loop for close to three hours. Each pass reveals another faint detail that simply was not there before.The main difference between the V4 and the V8 seems to come down to the type of mixing do. If it's usually along the lines of heavy stuff like rap and maybe film scores, the V8 will more than cover those styles of mixes in an average-size room. It feels like low-frequency saturation, with a deep richness. I suspect that most studios won’t even need a sub with this one. It’s all there.For those who want more low end KRK recommends the 12sHO subwoofer, although just about any sub in the KRK catalog would probably match just fine.While the V8 excels in the “thumpier” department, the V4s are almost perfect for classical, rock and jazz. Very accurate, and as noted earlier, with a surprising amount of low end.We live in a world of bigger means better, but these little guys are going to be hard to let go. I have a decent home stereo system for music and movies. In all honesty, except for the deepest lows, these things performed better than that 60-pound pile of gear. I don’t mean to gush, but they simply are so much better than I would have guessed.In comparison to the Rokit models that I checked out a while back, the increased definition of the V4 and V8 more than justifies their higher ticket price. I still firmly believe that most project studios will be very happy with the Rokits, but if the material is hypercritical, I strongly advise considering moving up to the V models.In my view, both groups are basically their own competition.
