Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality, rated 4.1/5, at $499.99; the Sigberg Audio INKOGNITO 12 ranks #64, rated 3.8/5, and costs $3,456.29, so there is not much of a tradeoff to weigh.
Why pick the Monoprice SW-15: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. The tradeoff: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
What the Sigberg Audio INKOGNITO 12 does well: An ultra slim sealed 12 inch subwoofer that mounts on a wall or slides under furniture, with parametric EQ. The catch: It is very expensive for a 250W sealed 12 inch subwoofer.
Buy the Monoprice SW-15. It is rated higher for sound quality than the Sigberg Audio INKOGNITO 12 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
