Product 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."

5.0 out of 5 stars Gave me the lows I was missing
Reviewed in the United States 🇺🇸 on August 9, 2022
Paired with my KRK Rokit 5s, it sounds amazing, essentially firing right in my face from behind my computer monitor. One interesting thing is, it does go into sleep mode after some hours of non-use. In sleep mode it does not pass a signal to the mid/high speakers connected to the sub, but only takes 4 seconds max, after receiving a signal to wake back up and gently bring up the main speakers. They have it set exactly right to not be annoying. Mine never enters sleep mode while I'm using my computer.

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.
