STUDIO MONITORING SOLUTIONS

KRK Systems is one of the world’s most respected manufacturers of studio
reference monitors. We achieved and have maintained this position by focusing
on accuracy, honesty and balanced spectral response with the goal of making
it possible for recording engineers to hear every nuance of the audio being
reproduced. KRK monitors are tools that are cherished by their owners as partners
in crafting great music and mixes.
For over a quarter of a century, we have been driven by a design philosophy of
precision, transparency, and at response. Our products deliver on this promise
through a combination of solid design and technical innovation. We were among
the rst manufacturers to take a quantum leap in woofer performance through
the use of Kevlar. Our VXT monitors are constructed from a remarkable material
that allows for its diraction-reducing shape while increasing internal cabinet
volume for better low frequency extension. The pinnacle of audio performance,
the KRK Expose E8B uses composite materials that provide the ultimate in detail
and accuracy. We were among the rst to introduce active (powered) monitors
that precisely match ampliers and electronics with the transducer elements.
These are all examples of innovations that produce tangible acoustic benets, not
a pursuit of the latest trends or fads. Our focus is your mix, and every monitor,
headphone and room correction system delivers on this commitment.
Whenyou chooseKRK, you join a family of elite producers, composers, performers
and engineers that rely on KRK products to deliver accurate sound reproduction
and acoustic precision, day in and day out. The signature yellow woofer of a KRK
monitor tells the world that you and your monitor are true to the mix and true
to your craft. KRK studio monitors enable you to condently make the critical

“With KRK Expose I was looking for a pair of speakers that were
consistent, and were easy to carry with me, that had enough
power to allow me to turn them up and be able to fill the control
room with music, but also a speaker that I could turn down and
get musical balances, and know that what I was hearing in the
studio I was also taking home. And it was a speaker I just bonded
with right away.”
Ed Cherney
Grammy andTEC award winning producer and engineer
The first thing I noticed was the comfort...just great. Then I was extremely impressed with the sound quality...clear and
natural. What struck me was how they didn’t sound as much like headphones, but more like KRK studio monitors. The more
I use KRK, from the headphones to my V8s to my E8s...what I have come to expect and enjoy is the extremely accurate and
consistent reproduction of sound. Just fantastic!” Johnny A.
Guitar Virtuoso/ Blues Artist of the Year 2010
EXPOSÉ TECH NOTE:
The E8B’s massive woofer construction is that of a
multi-layered sandwich, consisting of two layers
of Kevlar with a layer of Rohacell in between. The
woofer’s construction reduces distortion for greater
signal reproduction accuracy.
KNS TECH NOTE:
An innovative headphone acoustical system brings a
new level of headphone performance. Replaceable
components for long life.
KNS8400 features a detachable / replaceable sleek prole in-line high quality
volume control, and ear cushions with acoustic memory foam.

Professional recording studios, broadcast studios, serious project studios... these are demanding applications for any monitor. If you need more power, more
accuracy, more precision, more mounting options, look no further than KRK’sVXT line. Drawing upon the design characteristics of our Exposé E8B, theVXT product
family consists of the VXT8 near/mid-eld, theVXT6 neareld, and the VXT4 neareld, with bass response that is remarkable for such a compact cabinet.
All three models have a visually striking enclosure made out of structural foam. This material increases speaker performance by reducing cabinet resonance while
improving structural integrity. Due to its rigidity, this material allows the VXT to have more interior volume than other similarly sized speakers, which results in
extended low-frequency response.The VXT’s sleek curvature provides excellent imaging and a wider sweet spot giving engineers greater freedom to accurately
work their mix across the whole desk. Integrated in the front, the slotted bass port eectively minimizes port turbulence.The domed tweeter is made from true
silk for fast transient response.The low distortion woofer design features a sti and lightweight cone with a robust motor to control high dynamic peak excursion,
while delivering tight and accurate bass. Both transducers have vented formers to remove heat and reduce the eects of power compression — enabling these
monitors to maintain their sonic signature hour after hour, day after day. With uncompromising attention to detail that includes tamper resistant switch covers,
integrated mounting support, optional front grills and more, theVXT Series is an outstanding choice for a broad range of monitoring applications.

“What I like about the KRK VXT is two-fold: The Kevlar woofer is a wonderful thing; it gives and takes as
demanded by the music. The silk tweeter gives you a little more separation between the minute frequencies.
I monitor at whisper-quiet levels to downright loud, and there’s no ear-fatigue at all. I don’t know how you can make that
accurate of a speaker at the price range you do!” Dan Spitz

Just because your budget is smaller than that of a mega-studio doesn’t mean you don’t deserve a great set of monitors. For years, KRK Rokit
monitors have provided accurate sound for small personal, project as well as pro studios. The Rokit family brings KRK quality monitoring to
the masses.
All Rokits feature curved edges to prevent problems caused by early sound wave reflections of a traditional box enclosure. This results in a
better image in a wider area so even with small head movements you are always getting the best sound-staging. Rokit G2s also feature a
great looking cabinet with a front-firing bass port and a glass-aramid composite woofer for tight, punchy bass. The soft-domed tweeters
provide silky-smooth high-frequency response that does not fatigue. Dual high-power amplifiers in each speaker and active crossovers
provide solid power and crystal-clear detail. And Rokits are easy to connect in any desktop or studio environment by offering the flexibility
of RCA/Phono, ¼” and XLR inputs.This latest evolution in the Rokit series features an incredibly accurate response curve , and delivers
professional level studio monitor performance at an incredibly affordable price.
The newest addition to the family, the Rokit RP10-3, is a Mid-field 3-way monitor system in a compact form factor and at a breakthrough
price that delivers loud and accurate sound reproduction to satisfy professional needs. The RP10-3 will suit commercial facilities in need
of more capable mid-fields as well as space and budget conscious private studios. The high SPL output makes it capable of handling
challenging high dynamic tracks for all genres of music. The Rokit RP10-3 offers location flexibility by placing the tweeter and midrange
in a unique rotatable housing.Whether they are vertical, placed on their side or wall mounted – the proper orientation of the acoustic axis
can be maintained!

“KRK Rokit 5’s are true and consistent -- not hyped sounding. They also make you work for a great result which I like.
When the mix is sounding huge on them -- then I know I’m finished.”
Jacquire King
Record Producer, Mixer, and Engineer
ROKIT TECH NOTE:
Front-ring port provides low freq extension without
boundary coupling. Radically curved front plate
design virtually eliminates diraction distortion. The tweeter and midrange housing rotates for horizontal placement.

Surround sound mixing and today’s bass-heavy music demand accurate sound reproduction in the bass frequencies. Subwoofers allow you to use smaller main
monitors, make it possible to monitor the essential low frequency range and can be a great solution for space-challenged control rooms or mixing environments.
When dealing with subsonic frequencies -- if they cannot be heard accurately they cannot be mixed accurately.
The KRK12sHO powered subwoofer is the perfect High Output choice for professional studios, where ultra-accurate bass extension and maximum sound levels
are required. Powered by a massive 400 watt amplier and a strengthened version of our signature Kevlar woofer with ultra dense rigid multilayer dust cap, the
KRK12sHO is the no-compromise way to hear what is happening in the depths of your mix, capable of generating 123dB of SPL.
The KRK12s powered subwoofer is an ideal complement to KRKVXT series, KRK Rokit series, or any other 6”-10”studio monitor. The KRK12s is designed to extend
the response of an existing monitor system so that the low-frequency portion of the mix can be engineered. The KRK12s features the powerful accurate and low
distortion sound that is the hallmark of all KRK monitor systems. An ecient and low distortion 240-watt amplier makes the KRK12s perfect for project and
professional studio applications that require increased signal pressure.
The KRK10s powered subwoofer has a smaller form factor than the 12”models and is a great addition in a studio running KRK Rokit,VXT or any other 4”-8”studio
monitor. The KRK10s subwoofer also features a great looking cabinet that echoes the curved edges of the Rokit and VXT monitors. The front-ring bass port and
KRK’s signature yellow glass-aramid composite woofer ensure accurate and powerful low-end punch.

“I’ve always loved having a sub to wow record companies or artists when playing back a song or mix. The truth is, most subs
are only good for that purpose and are not accurate enough to work with when making a record. The KRK12s changed that.
It’s very accurate and actually makes my Expose’s sound even better!”

A great mix starts with a great recording room. But when it comes to achieving the most accurate mix, your room may have the upper hand. Like any room, your
studio’s acoustics include oending frequencies and room reections, and none of these are helping your mix. Getting a handle on these problems has traditionally
meant the installation of soft foam or fabrics, and that’s a great start. But now you can get even closer to a perfect room, and a perfect mix, because the future
of studio sound is here, and it’s called ERGO.
HEAR THE DIFFERENCE
KRK, long known for highly accurate studio monitors brings you ERGO (Enhanced Room Geometry Optimization). ERGO is an audio recording interface / room
correction system designed to measure and analyze phase/frequency problems within a listening environment. The powerful digital signal processor in the ERGO
unit processes audio to correct for the oending issues. So, you can stop worrying about your studio’s acoustics and start focusing on your mix! ERGO’s high-end
sound quality makes it perfect for the discriminating audio professional, while the aordable price puts it within reach of the typical recording hobbyist. Every
studio needs an ERGO, because even the most accurate monitor in an imperfect room isn’t going to solve mixing problems, but ERGO will. ERGO also makes your
mix translate from the studio to dierent environments.
THE BEST APPROACH
While many conventional room correction systems utilize simple analysis and limited bands of EQ (often fewer than 8), ERGO uses multiple measurements and
proprietary algorithms to create a 3D image of the room, and then applies 1024 dynamic lters to control the audio environment. Our 3D model allows users
to preserve the“good”characteristics of the room, while correcting the bad... ERGO doesn’t color the sound or produce an articially sterile environment. ERGO
produces the best mix for a given room; a mix that will translate better to other listening environments, since it was mixed in a“perfect”room.
ERGO
“Adding the ERGO to our setup has just further improved our experience with KRK by balancing our brand new studio without
having to discover and correct our rooms flaws through trial and error. It also helps to untie us from the studio by enabling
us to partially control any makeshift recording space we may end up in. I have a feeling that will be very useful with the
amount of time we spend on the road.” Manchester Orchestra
The sophisticated room analysis and correction system within ERGO, called“RoomPerfect” was developed by
Lyngdorf Audio in Denmark after many years of R&D work. The patented algorithm in the system compares
many measurements and corrects for phase and frequency problems using thousands of lters, not just a few.
The result is the most accurate mix. ERGO, analyze this!

TheAmerican Film Institute(AFI),foundedin1967,hasbeenaquintessentialforceinspiringtheexchange
of ideas between the entertainment and technology communities, especially in terms of“digital media”.
Intrinsic to “digital media” is high quality sound production, and this starts with quality monitoring
systems. Recently, AFI equipped 15 of their Editing Suites with 15 pairs of KRK Systems’VXT4 studio
monitors after receiving a number of complaints from AFI Fellows about their previous speakers not
translating from one environment to the next. Editing Fellows at the AFI Conservatory are responsible to
post the sound on more than 80 lms per year.
Currently riding a massive wave of millions of views on YouTube for the single “Tonight, Tonight,” the
band Hot Chelle Rae is destined for star status. Peaking on the Billboard Hot 100 chart at number seven
and now platinum “Tonight, Tonight,” oers bold, swaggering vocals, monster sing-along choruses,
crunching rock guitar and a propulsive rhythm section that just won’t quit. For on-the-go band member
Nash Overstreet (lead guitar/vocals), KRKVXT4s monitors save the day with accurate, portable reference
monitoring for projects in any acoustic environment or situation. According to Overstreet, “Having an
accurate mix/reference is crucial. Having monitors as small as the KRKVXT4s, which deliver great sound
WHILE being small enough to set up as studio reference monitors in a hotel room, green room or back
lounge of the bus is ideal.”
