#42 KRK S8.4: $299.99 Estimated Sweetwater eBay
Same family: the KRK S10.4 (larger subwoofer, estimated 3.6/5) and the KRK S12.4 (larger subwoofer, estimated 3.9/5).
Pros: The 8” studio subwoofer in KRK’s fourth generation, with a glass aramid woofer, a 109W Class D amplifier and a four-position crossover for pairing with Rokit monitors. Rated 34 to 133Hz (±3dB) and 113dB.
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). An 8” driver gives up deep bass and output to larger subs.
