Accurate Bass Monitoring for Your Home Studio!

The KRK 10s2 subwoofer is the perfect match for KRK's hugely popular Rokit and VXT monitor series, and with a 4-position crossover adjustable from 60 to 90 Hz, the 10s2 adds flexible, accurate low-frequency extension to any stereo or surround system.

Do I Need a Subwoofer?

There's a reason professional PA systems and movie theaters use dedicated subwoofer speakers: Main speakers work most efficiently when they're not saddled with reproducing everything from 20 Hz to 20 kHz. The main stereo speakers sound clearer and louder when they're not pushing out power-hungry sub-bass. A dedicated subwoofer fills in the lows so your main stereo monitors can work more efficiently in the mid-bass range on up to the highs.

Can you hear what's going on in the low end of your mix? Your mixes could be turning out more bass-heavy than you realize -- if you're mixing without a subwoofer. When your mix is played back on a large system, you don't want to get an unpleasant surprise. So add precise, tight bass monitoring to your setup, with a dedicated sub. 

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 10s2 sub's trademark yellow woofer cone, mounted discreetly behind a black grill. Like KRK's full-range Rokit and VXT monitors, the 10s2 also has a sleek curved baffle and front-firing port shaped to reduce turbulence. But unlike most studio monitors, the 10s2 is voiced to produce accurate, clear bass down to a deep 28 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 10s2. Next, run another pair of cables from the 10s2's outputs to the line-level ins on your stereo monitors. Set the sub's crossover to 90 Hz, its highest setting, and flip its phase inversion switch to the position loudest in your room. Then set the crossover to the appropriate setting for your room and speakers -- the 10s2's built-in crossover will send everything higher than the crossover point through its outputs to your main stereo speakers. 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 volume knob. 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 switch it to toggle Bypass.

Low End 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 10s2 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 10s2 for 5.1 mixing is easy, with a 4-position crossover adjustable from 60 to 90 Hz. You can set the 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 10s2 saves the day with a beefy 160 watts of power and a 10-inch high-excursion speaker cone -- more than enough to shore up your low end. The 10s2 is one of the most affordable-yet-professional subwoofers on the market -- and the ideal solution for a small studio that needs serious bass.
