Short answer: the SVS SB-3000, on output and accuracy. Its 13-inch sealed cabinet and 800W RMS (2500W peak) amplifier deliver 118.7dB average with exceptional accuracy, against the SB-2000’s 12-inch, 550W RMS (1500W peak) Sledge design. The tradeoff is that the SB-3000 is compact at 25 kg (55.1 lbs), which the source says limits bass extension, and it lists at $1099 against $899 for the SB-2000.
What the SVS SB-2000 gets right: Sealed 12” with 550W RMS, 1500W peak Sledge amplifier.
On the SVS SB-3000 side: 13-inch sealed with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy. The tradeoff: Ported cabinet room-mode dependency, compact 25 kg (55.1 lbs) size limits bass extension, and $1,100 investment.
Buy the SVS SB-3000. It is rated higher for sound quality, and the $200 saving on the SVS SB-2000 is not enough to make up the difference.

SVS SB-3000: $1,099.00 Amazon eBay
Pros: 13-inch sealed design with 800W RMS (2500W peak) that Audioholics measured at a 118.7dB CEA-2010-A average from 40-80Hz, and rated by SVS at 18-270Hz within ±3dB. Beautifully made with pinpoint control and flawless tonal accuracy. Sweet spot performance-to-value ratio. Three-band parametric EQ with 1Hz precision adjustment.
Cons: Being sealed, it gives up deep-bass output: Audioholics measured 96.6dB at 20Hz and 101.7dB at 25Hz, about 15dB behind the ported SVS PB-3000 from the same series, so a large room or reference-level movie bass may call for a second sub.
