## Description

"The S10.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy and performance. 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 makes it easy to adjust the subwoofer setting to your existing monitors. Pairing the S10.4 with KRK or another studio monitors delivers an optimized listening and mixing 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 S10.4 subwoofer doesn’t just deliver precise bass and a rich feature set: it’s the next dimension in subwoofer performance."

Review: Does bass <30hz & does it with accuracy. - A perfect match to my KRK V4S4 with the crossover set at 80hz. My JBL LSR310 sub had problems keeping up with the V4S4 output, even at -3db. Turning the JBL up to match output caused it to bottom out on bass heavy movies. The S12.4 stays clean & makes the bass needed to blend with the V4S4 with headroom to spare. Combined they are a soundbar killer. I've never heard a $4k soundbar but I'm guessing that's the starting point to match SQ of my set up. I'm using a Geshelli J3 DAC with V7 Classic opamps & a Topping A70 Pro as the preamp.
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!

### ⭐⭐⭐⭐⭐ When it kicks... it hits.
*by T***I on February 16, 2026*

Hands down the best subwoofer for a medium-sized room. Insanely responsive! It can hit those 20 Hz minimums without breaking a sweat. This thing gets LOUD. It's a hefty boy due to having the amp installed. We call these active speakers, kids. It is compact and will easily slide underneath your desk. I paired my subwoofer with the KRK Rockit 7 Gen 4s and have absolutely no regrets. The flat harmonics make this setup perfect for monitoring and music production.
