Our take on the KRK S12.4 12" Powered Studio Subwoofer

The KRK S12.4 is a 12-inch front-ported studio subwoofer with a 220-watt Class D amplifier, rated down to 26 Hz and up to 119.9 dB max SPL. It is built for project and home studios that need to hear and control low end the main monitors cannot reproduce. Its four-position crossover, input-sensitivity switch and ground-lift switch make it easier to match to KRK monitors and to tame hum. Against smaller 8- and 10-inch subs it goes deeper and louder, but it is a large, heavy cabinet at 62.5 lb, and it is wired only, with no Bluetooth or app control.

Pros
  • Deep low end: rated 26 Hz to 97 Hz, with usable output to about 23 Hz
  • Loud for its class: 220 watts continuous and 119.9 dB max SPL
  • Four-position crossover and input-sensitivity switch simplify matching to monitors
  • Ground-lift switch helps kill hum and ground loops

  • Balanced XLR and 1/4-inch inputs plus RCA for consumer gear
Cons
  • Large and heavy: 62.5 lb and nearly 24 inches wide
  • Wired only, with no Bluetooth or app control
  • Deep bass needs room treatment and careful placement to avoid boom
  • Single 12-inch driver and 220 watts may not fill large or loud rooms

What reviewers say

Owner and reviewer feedback on the S12.4 is limited, but the wider KRK subwoofer line is generally well regarded for solid, controlled low end and easy integration with KRK monitors. Buyers tend to value the crossover and ground-lift controls and accept the size as the price of real sub-bass.

Questions and answers

Will the S12.4 work with KRK Rokit monitors?
Yes. Its four-position crossover and input-sensitivity switch are designed to match KRK monitors, and it accepts balanced XLR or 1/4-inch connections.
How low does it go?
KRK rates it from 26 Hz to 97 Hz, with bandwidth of 23 Hz to 130 Hz at -10 dB, so it covers the sub-bass your main monitors miss.
Can I connect it to a home stereo or TV?
It has RCA line inputs alongside XLR and 1/4-inch, so consumer gear can feed it, but there is no Bluetooth or wireless option.
Is it loud enough for a large room?
It is rated at 119.9 dB max SPL, which suits most project studios. Very large or very loud rooms may want more output or a second sub.
Does it have a footswitch or app control?
No. There is no app control, Bluetooth or NFC; all settings are made with the rear-panel controls.
What is in the box?
The subwoofer and power cable. Audio cables are not included, so plan for XLR, 1/4-inch or RCA cables to connect your monitors and source.
