Quantity: Single Powered Subwoofer

LF Driver: 8"

Wattage: 109 Watts

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.

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.

    Great project & great quality
    Size: 38"Height × 14" Wide, Size: 38"Height × 14" Wide
    These legs were used on a 26”x72” DIY quilting ironing table. The Mdjwjj Industrial Pipe Counter Bar Height Table Leg, Metal Table Legs, Iron Base are sturdy & made of real metal, nothing cheap about this product. Legs were easy to install. Highly recommend

    Do it yourself
    Size: 38"Height × 14" Wide
    I purchased a similar set to custom make a dining room table out of butcher block, and it turned out perfect. So with the left over butcher block I purchased these legs and made the perfect kitchen island to match. It is very sturdy and a great price. Everyone wants to know where I purchased it from. I also put a piece of the butcher block across the lower bars and made a lower shelf. Love love love this.

    Plan your project right & these will look great!
    Size: 38"Height × 14" Wide
    These are great legs for a table. They are sturdy and go together nicely. The painted finish is well done, meaning it doesn't scratch or peel or come off easily. Also the way things were packaged was considerate of the weight and possibility of damage during shipment. There were even extra attachment screws included which was helpful since I lost one under the dishwasher. When considering what legs to purchase for your particular table, the height, dimensions, and weight of the top all need to be factored in. I used these bar height legs under a very heavy, 7' long X 2' wide top. Common physics dictates that there will be lateral movement between the 2 "H" shaped leg sets. There HAS to be support between the 2 H leg sets to prevent that lateral movement. So these alone will not support a long table very well, because physics. This is not in any way the fault of this product. Be aware that there is more to the stability equation and be prepared to add cross bracing to your project.
