#139 KRK S10.4: $479.00 Estimated Sweetwater eBay
Same family: the KRK S8.4 (smaller subwoofer, estimated 3.3/5) and the KRK S12.4 (larger subwoofer, ranked higher, estimated 3.9/5).
Pros: The 10” studio subwoofer in KRK’s fourth generation, with a glass aramid woofer, a 160W Class D amplifier and a four-position crossover. Rated 30 to 110Hz (±3dB) and 117dB, with balanced XLR and TRS inputs for studio use.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from KRK’s measured 12S (117.1dB in the 40 to 80Hz CEA-2010 bands), which it is not expected to match.
