Product Description for the KRK 12sHO
Ah, subwoofers. They're great for impressing your artists and clients with rich, thick low-end punch. But do you find yourself turning off the sub when the guests leave, because you need to get some actual work done? Let's face it: if your subwoofer isn't accurate enough to trust for serious mixing and mastering, it's just dead weight in your studio. To build mixes that sound good played back on consumer 2.1 or 5.1 systems, you need a sub that delivers precise low-end to complement your existing monitors -- and if your existing monitors happen to be particularly powerful, KRK's 12sHO sub is up to the task. Exceeding your sub's headroom will be out of the question, with the 12sHO's meaty 400-watt amplifier pushing a reinforced version of KRK's signature yellow Kevlar 12-inch cone. The "HO" in 12sHO stands for "high output" -- and with an astonishing 123 dB peak SPL, that's exactly what this top-of-the-line subwoofer delivers.
Designed to integrate equally well with surround or stereo monitoring environments, the 12sHO features 1/4-inch/XLR combination jacks for stereo full-range inputs, plus a LFE (low-frequency effects) combi jack for your 5.1 system's dedicated channel. Stereo setup couldn't be easier: connect the outputs from your console or audio interface to the 12sHO's inputs, and feed your left and right monitors from the 12sHO's balanced XLR line outs. Since these line outputs have a fixed 80 Hz high-pass filter, you'll want to turn the 12sHO's low-pass frequency adjustment knob to 80, so it only produces frequencies below that point. Want to use your own external crossover with subwoofer output connections? No problem: the 12sHO's input low-pass filter is sweepable from 60 to 160 Hz. Flexibility is the name of the game with this truly pro piece of gear.
Fine Phase Control, Footswitch Bypass, and More
The KRK 12sHO was designed to do one thing: reproduce a whole lot of clear, precise bass down to 29 Hz. But for a box that does only one thing, the 12sHO certainly packs in a host of high-tech features. On the back panel, you'll find not only a polarity flip switch, but a fine-tune phase-adjustment pot for time-aligning your sub with the rest of your speakers, using test tones available on KRK's website. There's also a defeatable limiter that greatly reduces any risk of harming a driver, and a voltage selector that allows you to use this sub in any studio in the world. Plus, the included KFS-1 footswitch lets you tap your foot to mute the sub, bypass the filters, and send full-range audio to your stereo monitors via the line-outs. It's the easiest way to hear how the 12sHO is complementing your mix.
KRK's Recognizable Design Goes Pro
Boasting a somewhat more sophisticated design than KRK's popular project-studio-workhorse offerings, the 12sHO still features a gently curved baffle and innovative front-firing ports, optimized to prevent turbulence. Both rubber and spiked feet are included for use on any carpeted or hard floor surface. And of course, KRK's trademark yellow cone stands out in the 12sHO's design. Whether it's the "point 1" of your 5.1 system, or a low-frequency extension of your stereo studio monitors, the 12sHO is a pro-level sub suitable for the most demanding studio applications.
