    KRK S12.4 Generation 4 12" 220 Watt Powered Subwoofer

    Stop guessing what your low-end sounds like and start mixing with actual confidence. The KRK S12.4 Generation 4 subwoofer is here to act as the bedrock of your studio, delivering the kind of tight, accurate bass that transforms muddy productions into polished gems. It doesn't just add volume; it adds clarity, ensuring that what you hear is exactly what you get.

    With a massive 220-watt Class D amplifier driving a 12-inch Kevlar composite woofer, this sub offers serious muscle without the flab. Whether you're tracking heavy synths or dialing in a kick drum, the S12.4 provides the transient response and punch you need to make critical decisions. It’s the studio partner that never lies to you.

    Precision Performance, Total Control

    KRK has long been the gold standard for studio monitoring, and the S12.4 takes that legacy to new depths — literally. It’s designed not just to move air, but to move it with purpose, giving you a defined low-end extension down to 26Hz.

    • 12" Kevlar Composite Woofer: This isn’t your average paper cone. The custom glass-aramid composite woofer is lightweight yet incredibly rigid, minimizing distortion even when you crank the volume. The result? Bass that hits you in the chest but remains tight and articulate, avoiding the dreaded "one-note" boominess of lesser subs.
    • Class D Amplification: Efficiency meets power. The 220-watt Class D amp runs cool while delivering serious headroom. It dramatically improves transient response, meaning fast bass lines and percussive hits are reproduced with razor-sharp accuracy.
    • 4-Position Crossover: Your room and your monitors are unique, and the S12.4 respects that. The four-position selectable crossover lets you dial in the perfect hand-off frequency between your sub and your full-range monitors, ensuring a seamless, cohesive soundstage rather than two disjointed sound sources.

    Workflow That Works for You

    A great piece of gear shouldn't slow you down; it should speed you up. The S12.4 is packed with thoughtful features that integrate smoothly into your existing workflow, solving common studio headaches before they even happen.

    • Front-Firing Port: Placement matters. Unlike rear-firing subs that can create turbulent, muddy bass when placed near walls, the S12.4 features a front-firing port. This design reduces boundary coupling, giving you more flexibility in where you place the sub while maintaining clean, punchy low-frequency extension.
    • Ground Lift Switch: Hum and buzz are the enemies of a clean mix. The dedicated ground lift switch is your secret weapon against ground loops, ensuring your signal remains pristine and noise-free.
    • Footswitch Bypass Control: This is the feature you’ll wonder how you lived without. With an optional footswitch, you can instantly bypass the subwoofer and send full-range audio to your main monitors. It allows you to quickly check how your mix translates to systems without a sub, all without leaving the sweet spot.

    KRK S12.4 Built for the Real World

    Built for the Real World

    Studio gear takes a beating, but the S12.4 is ready for the long haul. From its robust cabinetry to its universal connectivity, every inch of this sub is engineered to handle the rigors of daily production work while looking professional in any setup.

    • Reinforced MDF Enclosure: A vibrating cabinet is a noisy cabinet. The S12.4 features an 18mm reinforced MDF enclosure that provides maximum strength and density. This heavy-duty construction kills unwanted resonance dead, ensuring that the only thing vibrating is the air in the room.
    • Universal Connectivity: Whether you’re running a pro rig or a modest home setup, the S12.4 plays nice with everything. It comes equipped with XLR, 1/4" TRS, and RCA inputs and outputs, meaning you can hook it up to virtually any interface or mixer without a tangled mess of adapters.
    • Redesigned Form Factor: KRK shaved down the height and depth compared to previous generations, giving the S12.4 a lower profile that fits easier under desks or in tight corners, all while maintaining that timeless, professional aesthetic.

    The Next Dimension in Low End

    The KRK S12.4 isn't just an upgrade; it's a revelation. By combining power, precision, and practical features like the bypass footswitch, it empowers you to produce better mixes, faster.
