Short answer: both are discontinued, so this only matters if you are buying used. Used, the Onkyo SKW-204 is the better pick: it ranks #3 of 73 subwoofers by sound quality (rated 3.8/5), against #14 (rated 3.6/5) for the Velodyne Acoustics SPL-1200 Series II. If you want one new, the Edifier T5s ranks #2 at $169.99.
What the Velodyne Acoustics SPL-1200 Series II does well: A discontinued compact sealed 12 inch subwoofer with good output for its small footprint, a fit for smaller rooms. The catch: Small sealed driver limits extension below 20 Hz and 20.9 lbs (9.5 kg) compact size.
What the Onkyo SKW-204 does well: A discontinued ported 10 inch subwoofer with strong upper bass punch for movies and music at a budget price. The tradeoff: 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.
Buy the Onkyo SKW-204 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Edifier T5s instead.
