KRK S8.4 S8 Generation 4 8" 109 Watt Powered Studio Subwoofer

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!

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.

Excellent sound. Excellent translation and an excellent product. Well worth the price! Highly recommended and I have a very large mixing room (although well treated).

Definitely the missing piece to my existing 2 speaker KRK set up! Decent value for money, good volume control, and great clarity. The size is very awkward and requires a lot of space. The weight is also a little much and is hard to maneuver. My favorite feature is the sleep option that you can toggle on and off. There's no bluetooth that I'm aware of, but as far as connecting everything correctly, it was easy to decipher.

Not the deepest base (only 8 inches) but it makes up for it in the punch in a 20x20 basment. im satisfied.. The available connectors and built in crossover for the price is what makes this a deal. Great for beginners but if you have the money you cant go wrong with the 10 inch

Sounds great changed polarity and thing was rocking the house lol

IT BANGS!!!! Excellent sound.

The Sub won't stay on, I check the fuse and took it off Stand-by mode, what is wrong smh! Awesome sound, I would give it 5 stars if it wasn't for the thing turning off not coming on every now and than.

Fast delivery service, much faster than mentioned. The sound quality is absolutely perfect. Working fine with my Krk's studio monitors . Perfect for home studio setup

Excelente equipo, un muy buen complemento para los monitores de la misma marca.

Some of the items are messing (metal cover, cable power) and the product damaged from the corner

I'm using with Focal Solo 6 tops to provide greater low-end definition. After a lot of research, the KRK 8.4 sub suited my needs. I'm also using it with a sustain pedal to cut out bass sometimes. Was able to dial in the sound while listening to commercial music very quickly. I also got the ISOacoustic sub stand for my neighbours below. Overall sound seems very accurate. Very happy with package. Came earlier than expected.

Muy buena calidad
