## Customer Reviews

### ⭐⭐⭐⭐⭐ Very nice for music (heavy, solid, no rattles/booms, no hum, perfect back-panel controls)
*by C***R on April 6, 2025*

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!

### ⭐⭐⭐⭐⭐ Arrived flawless, sounds incredible!
*by N***  on March 10, 2025*

Subwoofer was shipped promptly and reached my house within a couple days. Package was in pristine condition and this thing sounds SO GOOD. Was wanting this to complete my home studio setup, since I already have the 8" Rokits. If you're on the fence about getting the subwoofer, just do it. This makes mixing the low end in heavy music much easier and a lot more enjoyable. Great sound, very well balanced and powerful.

### ⭐⭐⭐⭐⭐ Big booms!!
*by J***D on April 5, 2025*

Big ol booms. Love these speakers.
