Most home studios start out as smallish, square-ish rooms -- not the ideal setting for an accurate listening environment. Corner bass traps and absorbent wall panels can help eliminate muddy low-frequency buildup. But even when room acoustics are under control, your mixes could be turning out more bass-heavy than you realize -- if you're mixing without a subwoofer. So the next logical step is to add precise, tight bass to your setup, with a dedicated sub. The KRK 10S subwoofer is the perfect match for KRK's hugely popular Rokit and VXT monitor series, and with a sweepable crossover set anywhere from 50 to 130 Hz, the 10S adds flexible, accurate low-frequency extension to any stereo or surround system.
Unmistakable KRK Design
KRK is a "do one thing, do it well" kind of company, which is why their studio monitor speakers have become ubiquitous in home project studios and professional setups alike. If you've been in your share of studios, you're likely to recognize the KRK 10S sub's trademark yellow glass aramid composite woofer cone, mounted discreetly behind its removable black grill. Like KRK's full-range Rokit and VXT monitors, the 10S also has a sleek curved baffle and front-firing port shaped to reduce turbulence. But unlike most studio monitors, the 10S is voiced to produce accurate, clear bass down to a deep 34 Hz.
Simple Steps To a Stereo Setup
If you're adding a sub to your stereo monitors, setup couldn't be simpler: run a pair of cables (XLR, 1/4-inch, or RCA) from the stereo outs of your console or audio interface, to the stereo inputs on the KRK 10S. Next, run another pair of cables from the 10S's XLR or RCA outputs to the line-level ins on your stereo monitors. You'll want to try moving your subwoofer around the room to find the right spot, and use pink noise and test tones from KRK's website to make sure your levels are properly matched -- and if they're not, adjust the sub's -30 to +6 dB volume knob. Set the sub's low-pass filter to 130 Hz, its highest setting, and flip its phase inversion switch to the position loudest in your room. Then set the sweepable low-pass filter to 80 Hz -- the 10S' built-in crossover will send everything higher than 80 through its outputs to your main stereo speakers. And that's it: you've got a properly calibrated subwoofer holding down the low end on your mixes.
Bypass Footswitch: Hear The Difference
You'll hear the difference your subwoofer makes in your system immediately -- but KRK also makes it even easier to "A/B" your system. The Bypass feature lets you send the full-range stereo signal to your main monitors, bypassing the sub entirely, with no plugging or unplugging of cables. Just plug in a standard 1/4-inch latching footswitch like the Boss FS-5L to the back panel and "click" it to toggle Bypass.
Sweepable Low-Pass for Surround Monitoring
Accurate sub-bass monitoring is key for mix-to-picture applications. It's an obvious must if you're building a real 5.1 surround setup. And when you're doing audio post on a stereo system, a KRK 10S sub can help you zero in on undesirable noise like air-conditioner rumble and pops on voiceover tracks, as well as set precise levels on low-frequency effects. After all, if you're mixing a soundtrack that will be reproduced on theater systems with sub-bass capabilities, you need to have those frequencies represented in your studio. Luckily, setting up your 10S for 5.1 mixing is easy, with a low-pass filter sweepable from 50 to 130 Hz. You can set the low-pass frequency depending on the size of your left, right, center, and surround speakers, and what your bass-management hardware or software requires.
Send In The Sub!
Small stereo monitors such as KRK's Rokit RP5 have become increasingly popular in budget-minded home studios -- and compromised low-end is unavoidable when you're using small speakers. Do the math: for every octave lower, a speaker needs to push 4 times as much air to maintain the same volume. Fortunately, the KRK 10S saves the day with a beefy 150 watts of power and a 10-inch high-excursion speaker cone -- more than enough to shore up your low end. The 10S is one of the most affordable-yet-professional subwoofers on the market -- and the ideal solution for a small studio that needs serious bass.

Am Updated Standard in Low Frequency Monitoring
For years, KRK subwoofers have been the choice for accurate low frequency monitoring in studios large and small. Now, the K10s provides a standard for even better performance and accuracy, raising the bar once again. Whether you are mixing in a 2.1 or 5.1 surround environment or just looking to upgrade the low-frequency extension of your existing monitors, the K10s will provide the low frequency detail and accuracy that will help you to create a better mix.
Let's Be Up Front
Take a look at competitive subwoofer monitors and you'll find ports on the back of the cabinet. These rear-firing ports tend to create bass coupling with walls and corners over-amplifying low frequency information which in turn colors your mix. The superior design of the KRK10s includes front-firing ports which are just the right shape to reduce port turbulence. You'll appreciate the clean and accurate bass performance this approach delivers, even at high SPLs.
Feel the Bass
You need to feel the bass and the proprietary signature yellow woofer delivers tight, clear low end response. Engineers and a listening panel took the K10s speaker voicing to even more accurate levels. Featuring a sweepable 50 Hz - 130 Hz low pass filter, your K10s provides flexible control for any monitoring system. What you hear is what you are intended to hear, coloration is not part of the spec. This performance is brought to you by drivers that are custom-designed by a world-class studio monitor engineering team, for a clear, low-distortion performance.
Professional engineers like the ability to hear how the sub is affecting the mix. Your KRK subwoofer is equipped with a bypass feature which allows you to defeat the sub and provide full range audio to your recording monitors. To use the bypass function, you will need to use a standard latching 1/4 mono footswitch.
