Short answer: the SVS SB-5000 R-Evolution is the newer model that replaces the SVS SB-4000, but only the SVS SB-4000 has been measured and ranked so far, so this comparison is on specs and features rather than sound. The SVS SB-4000 is discontinued, so it is now a used buy.
What the SVS SB-5000 R-Evolution offers: Sealed 15-inch high-excursion driver with a 2,000W RMS dual-monoblock amplifier and a 295MHz DSP.
What the SVS SB-4000 brings: Independent CEA-2010 testing records 98.5 dB at 20 Hz and 120.1 dB (avg of 3/4 bands) through 40-80 Hz.
Price: the SVS SB-5000 R-Evolution lists at $1,999.99 and the SVS SB-4000 at $1,800.
Buy the SVS SB-4000 if you want a speaker whose sound quality has been measured and ranked.
Buy the SVS SB-5000 R-Evolution if you want the newer model, and you can wait for measurements to confirm how it sounds.

The Two Speakers In Full
SVS SB-5000 R-Evolution: $1,999.99 SVS eBay
Older model: the SVS SB-4000 (rated 4.2/5).
Pros: Sealed 15-inch high-excursion driver with a 2,000W RMS dual-monoblock amplifier and a 295MHz DSP. SVS rates it at 17-280Hz within 3dB. The SVS Subwoofer Control app adds DSP control and Auto EQ room calibration.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. A sealed box trades some deep-bass output for tighter response compared with a ported design of the same size.

SVS SB-4000: $1,800 Discontinued eBay
Newer model: the SVS SB-5000 R-Evolution. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: Independent CEA-2010 testing records 98.5 dB at 20 Hz and 120.1 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 13.5” (343mm) driver delivers formidable upper-bass output for movie effects and music.
Cons: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority. The 464.8H x 452.1W x 472.4D mm cabinet and 46.4 kg mass still require deliberate placement and calibration. Discontinued.
