Short answer: the Monoprice SW-15. Both are rated 4.1/5 for sound quality (#13 and #14 of 145 subwoofers), and the Monoprice SW-15 costs $374.99 against $1099 for the SVS SB-3000, with sound quality a draw, the lower price decides it.
What the Monoprice SW-15 gets right: 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. Set against that: Budget-tier design, ported room gain dependency, 30 kg (66.1 lbs) mid-size, and limited dynamic headroom.
On the SVS SB-3000 side: 13-inch sealed with 800W RMS (2500W peak) delivers 118.7dB average with exceptional accuracy. The catch: Ported cabinet room-mode dependency, compact 25 kg (55.1 lbs) size limits bass extension, and $1,100 investment.
Buy the Monoprice SW-15. Both are rated the same for sound quality, and it costs $724.01 less than the SVS SB-3000.

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.
