## 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: Excelente equipo, un muy buen complemento para los monitores de la misma marca.
Review: It's Incredibly powerful for its size & produces clean tight bass, however I noticed the bass starts distorting once the sub gets hot but once you let it cool it sounds clean again. I'd avoid usage at loud volumes for long periods of time as the amp can get really hot. For mixing bass frequencies lower than 32Hz I strongly recommend going with the S10.4, I would've gotten that but I live in an apartment building and would never be able to get the most out of it without being a nuisance to my neighbors.
