Critic Reviews

KRK S12.4: Super Studio Sub | DJ Times Magazine

djtimes.com

The KRK S12.4 powered studio subwoofer packs a punch with its robust build and impressive sound clarity, thanks to its durable Kevlar woofer and front-firing bass port. At 62.5 pounds, it's hefty but delivers deep bass down to 26Hz, making it a strong contender for any studio. Features like multiple input options and a useful footswitch are notable, enhancing its usability. However, while the sound is clean, it can get overwhelmingly loud, potentially overpowering in smaller spaces. Additionally, its weight makes portability a concern. Overall, for those needing a powerful sub with great sound quality, the S12.4 is a worthy investment.
