Short answer: the SVS SB-3000 on overall measured output, the RSL Speedwoofer 10S MKII on price and deep-bass value. The SB-3000 ranks #124 of 212 medium powered subwoofers against #15 for the Speedwoofer 10S MKII, and it costs $700 more.
The output comparison is more nuanced than the ranking gap suggests. At 20Hz and 25Hz, the ported RSL actually measures louder than the sealed SB-3000: 100.0dB against 96.6dB at 20Hz, and 105.0dB against 101.7dB at 25Hz. The two are essentially tied at 31.5Hz. Above that, the SB-3000 pulls decisively ahead, reaching 118.7dB at 50Hz and staying above 120dB through 125Hz, while the RSL peaks around 113dB in the same range and tapers off toward 100Hz. That gives the SB-3000 a CEA-2010-A average of 118.7dB against 112.1dB for the RSL.
Both bring genuine DSP tools, at different levels of precision. The RSL includes dual DSP modes, an LFE mode tuned for 22Hz extension and a Music mode for tighter response, plus a built-in wireless receiver. The SB-3000 offers a three-band parametric EQ with 1Hz precision adjustment and an adjustable 30-200Hz crossover with multiple slope options, finer control if you want to tune in a specific room.
The SB-3000 is also the larger, heavier unit: 54.5 lbs (24.7 kg) against 40.6 lbs (18.4 kg) for the RSL, with an 800W RMS amp (2500W peak) against 400W RMS (1020W peak) for the RSL.
Buy the SVS SB-3000 for the strongest output through most of the bass range and finer-grained EQ control, if the higher price fits your budget.
Buy the RSL Speedwoofer 10S MKII if you want strong output specifically in the deepest bass below 30Hz at less than half the price, and don’t need maximum output higher in the bass range.
