The KRK S10.4 subwoofer is the missing link that transforms your monitors from mere speakers into a surgically precise sound system. Built on KRK's legacy of sonic accuracy, this 10-inch beast delivers the tight, defined low-end that separates polished, professional mixes from muddy bedroom demos.
It’s not about adding more boom — it’s about adding the right boom, revealing the crucial frequencies your monitors can't reach. Stop guessing what's happening in the low end and start mixing with confidence.
The Secret Sauce Behind the Sound
If you're ready to elevate your mix game and give your tracks the rock-solid foundation they've been begging for, then prepare to meet the engineering marvels that make it happen.
Custom-Voiced Glass-Aramid Woofer: This isn't your average speaker cone. The glass-aramid construction delivers bass that's both powerful and articulate, giving you low frequencies that cut through dense mixes without turning into muddy rumble.
Class-D Power Amplifier: Forget the days of sluggish bass response. The highly efficient Class-D amp delivers lightning-fast transient response and tight control, so your kick drums hit with precision and your bass lines stay defined.
Four-Position Crossover Selection: No guesswork, no trial and error. Simply dial in the perfect crossover point to match your existing monitors, creating a seamless transition from your mains to the subwoofer.
Studio-Ready Functionality
The S10.4 was designed by engineers who understand that studio work demands both flexibility and reliability.
Bypass Footswitch Control: Step on the optional footswitch to instantly compare your mix with and without the subwoofer, all without leaving your sweet spot or breaking your creative flow.
Full-Range Monitor Bypass: When the sub is bypassed, your monitors receive the complete frequency spectrum, letting you make critical mixing decisions with surgical precision.
Universal Monitor Compatibility: Whether you're running KRK monitors or another brand, the S10.4 integrates seamlessly into your existing setup.
Robust Construction and Smart Design
Studio gear takes a beating, and the S10.4 is engineered to handle whatever your creative process throws at it.
Reinforced MDF Enclosure: The heavy-duty cabinet construction eliminates unwanted resonances while providing the structural integrity needed for accurate bass reproduction.
Front-Firing Port Design: The engineered port shape reduces boundary coupling issues and eliminates port turbulence, giving you clean, extended low-frequency response regardless of placement.
Compact Profile: The redesigned cabinet offers improved placement flexibility with a lower height profile and reduced depth compared to previous generations, fitting into studios where space is at a premium.
