Short answer: both are discontinued, so this only matters if you are buying used. Used, the PSB Speakers SubSeries 450 is the better pick: it ranks #6 of 167 subwoofers by sound quality (rated 4.2/5), against #54 (rated 2.6/5) for the PSB Speakers SubSeries 100. If you want one new, the SVS SB-3000 R|Evolution ranks #3 at $1,299.99.
What the PSB Speakers SubSeries 450 does well: 12-inch passive radiator with 400W RMS (1000W peak).
What the PSB Speakers SubSeries 100 does well: Independent CEA-2010 testing records 78.1 dB at 20 Hz and 99.2 dB (avg of 3/4 bands) through 40-80 Hz. The catch: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects.
Buy the PSB Speakers SubSeries 450 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 SVS SB-3000 R|Evolution instead.

PSB Speakers SubSeries 450: $1,898.91 Discontinued eBay
Pros: 12-inch passive radiator with 400W RMS (1000W peak). Pitch definition and precision equal to far pricier designs. Bass hits hard and tight without lingering in room. Strong presence in bass guitar range for music. Does it all well.
Cons: Discontinued.

PSB Speakers SubSeries 100: $299 Discontinued eBay
Pros: Independent CEA-2010 testing records 78.1 dB at 20 Hz and 99.2 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 5.25” (133mm) driver is best suited to upper-bass support in a modest room.
Cons: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects. The 161.8H x 161.8W x 199.9D mm cabinet and 2.7 kg mass still need deliberate placement and calibration. Discontinued.
