Short answer: the SVS SB-2000 Pro. It ranks #72 of 212 subwoofers by sound quality, rated 3.8/5, at $749. The RSL (Rogersound Labs) Speedwoofer 10S MKII ranks #124, rated 3.6/5, at $499, $250 cheaper, a saving that is not big enough to make up the sound-quality gap.
The two take opposite approaches to the same job. The Speedwoofer is a 10-inch ported design with a 400W RMS (1020W peak) XDR amplifier and a DSP with two modes: an LFE mode tuned for extension down to 22Hz, and a Music mode tuned for tighter response. The SB-2000 Pro is a sealed 12-inch design with a 550W RMS, 1500W peak Sledge amplifier, aiming for the smoother rolloff a sealed box gives up in favor of one that reaches lower.
In measured output, the SB-2000 Pro is ahead. At the CEA-2010-A average across 40 to 80Hz, the SB-2000 Pro measures 114.7 dB in Erin’s Audio Corner’s testing against 112.1 dB for the Speedwoofer in Audioholics’ testing, and it leads at every band from 20Hz to 80Hz, by 2.5 dB at 20Hz and about 8 dB at 25Hz. The two were tested by different outlets, so treat gaps of a dB or so with caution.
What the SB-2000 Pro adds: full smartphone app control with parametric EQ, a 5-year warranty, and a sealed cabinet many buyers prefer for tighter, more predictable bass in a compact footprint. The Speedwoofer’s warranty isn’t listed, but it does include a built-in wireless receiver the SB-2000 Pro lacks.
Buy the Speedwoofer 10S MKII if saving $250 matters more to you than the SB-2000 Pro’s extra output and app-based EQ control.
Buy the SB-2000 Pro if you want a sealed enclosure and full parametric EQ from SVS’s app, and the extra cost isn’t a concern.
