Its curved front-firing bass port allows flexible placement, while selectable crossover settings and footswitch control enable seamless integration with studio monitors. Designed for professional music production, it offers tight, distortion-free low frequencies that elevate mixing and listening experiences.

## Description

"The S8.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy in a compact form factor. The custom-voiced, glass-aramid woofer delivers tight, defined bass, while the Class-D power amplifier dramatically increases transient response, control and punch. The four-position selectable crossover lets you adjust the subwoofer setting easily to your existing monitors. Pairing the S8.4 subwoofer with KRK or another studio monitor delivers an optimized mixing and listening experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. KRK’s S8.4 subwoofer doesn’t just deliver precise bass and a rich feature set: it’s the next dimension in subwoofer performance."

Review: Very nice for music (heavy, solid, no rattles/booms, no hum, perfect back-panel controls) - I was looking to add a sub to enhance the bass in my music. I'm a long-time audiophile who has owned many subs over the decades. My fronts (JBL 530s) are beautiful but have only 5.5" drivers and drop off precipitously below 70hz. The bass in my music is played by instruments, not computers- nothing below 35hz is needed. This placed me in the market for a tight 8" sub. A key attribute I demanded was the ability to defeat the "Standby" setting, as a sub turning on and off is unlistenable to. (Don't believe the BS that you can't hear this.) The KRK 9 emerged and I purchased it. It has a perfect set of back-panel controls. I calibrated and evaluated everything using test-tone webpages and careful listening to music I know by heart, a method easier and far more accurate than YPAO. This sub is heavy, solid (no rattles/ "booming"), no hum, and plays well in the octave I need. Yes, it's expensive, but it actually enhances my sound quality for music. I've attached a photo of the optimal controls when paired with very capable bookshelf speakers. There is a 2009 remaster of "Seconds Out" by Genesis and in the song "Firth of Fifth" you hear clearly and distinguished the bass guitar and bass drum. This is a new revelation to me for an important piece of music. Bravo!
Review: Perfect addition to v8’s - Amazing sound. Finally got to pair the 8 inch sub with my krk v8 series 2 monitors I got in 2004, which still to this day, are my daily monitors for my log cabin studio. This added that low end I was lacking. Now just to get a center and surrounds. I think I’ll aim for a small rokit kit for this.
