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.

Bypass Footswitch

Mix with confidence. The bypass footswitch control allows you to quickly mute the sub and send full-range audio to your recording monitors.

Heavy Duty Enclosure

KRK Subwoofers feature reinforced MDF enclosures for maximum strength and durability. Never let a spilled beer or wild ninja roundhouse kick stop your mixing session again.

Front-firing Port

We engineered the front port to provide low frequency extension while reducing boundary coupling. The unique shape is optimized to avoid port turbulence.

Plays well with others

Dedicated crossover and optional High-pass filter bypass means that our subwoofers are the perfect compliment to powered monitors. From mixing and mastering to sound design, broadcast and production work - KRK has you covered.

Just what we needed
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
This toy has been great for my dog who eats all her toys! We were having such an issue with all of her toys being so hard that we didn’t want to throw them around our house. This was the perfect solution. She hadn’t eaten through it and it’s nice and soft for fetch without destroying your house!

My lab loves t
Color: Orange & Blue Fumbler, Size: 3 x 8.5 x 9 inches (1 Pack)
This toy is my labs favorite toy. She’s obsessed and we were happy to find a toy she loves that can stay inside with us. The problem is how easily she tears it apart. We have to buy her a new one every month because when she bites into it it breaks down the foam inside, and from there she shreds the roping it’s covered in. We try to stop her, but with how often we play with it it’s inevitable. We have resigned ourselves to buying a new one once a month.

Worth the purchase
Color: Orange & Blue Fumbler, Size: 3 x 8.5 x 9 inches (1 Pack)
Perfect for indoor use. My aggressive chewer loves this and has not destroyed it yet after 6 months. I recommend for indoor use as it causes NO damage or noise.

Not Chuck-It Durable
Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack), Color: Orange & Blue Squirrel, Size: 4.7 inches (1 Pack)
Sadly only lasted an hour. My dog likes to pull apart toys over the course of a few months, with the exception of Chuck-It toys. They usually never get destroyed by him. I think its a good product but if you are looking for the durability like other toys from Chuck It - just wanted to share this is not the toy for you! Made him happy so not regretful of buying it, just wish it lasted longer. Here is him posing with it after he took bites of it like it was an apple.
