Powered Studio Subwoofer The S12.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy and stellar performance. The custom-made, Kevlar woofer delivers ultra-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 S12.4 with KRK or another studio monitor 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. The powerful S12.4 subwoofer doesn’t just deliver precise, ultra-low bass and a rich feature set: it’s the next dimension in subwoofer performance.

The biggest fattest low end you can wish for, the variable frequency switch in the back is superHelpful. Loads of clean power.

Been using this for a couple of weeks now and so far I'm enjoying it a lot. If you're looking at KRK gear then you obviously don't mind a coloured frequency response leaning towards heavy low end, you can set this up to be a nice extension of the LF or it can blow your head off for general listening. It sounds great to me, is built like a tank, has solid tuning options on the amplifier. Doesn't come with a grille though so if it's in the foot zone then definitely look into investing into one of those so you don't put a foot through the driver.
