Short answer: the PreSonus Eris Sub 8BT. It ranks #8 of 48 subwoofers by sound quality, rated 3.6/5, at $209.99; the Dayton Audio SUB-1000L ranks #20, rated 3.4/5, at $209.98. The price gap is small enough that the sound-quality ranking should decide it.
The case for the PreSonus Eris Sub 8BT: Independent CEA-2010 testing records 77.7 dB at 20 Hz and 111.3 dB through 40-80 Hz. Watch for: Warranty is a below-average 1 year.
Why pick the Dayton Audio SUB-1000L: Independent CEA-2010 testing records 89.9 dB at 20 Hz and 110.0 dB through 40-80 Hz. Watch for: Deep-bass output is limited relative to its midbass result, so it is not the right choice for the lowest movie effects.
Buy the PreSonus Eris Sub 8BT. It is rated higher for sound quality, and saving $0.01 with the Dayton Audio SUB-1000L does not make up for the sound-quality gap.

PreSonus Eris Sub 8BT: $209.99 Amazon eBay
Pros: Independent CEA-2010 testing records 77.7 dB at 20 Hz and 111.3 dB through 40-80 Hz. The ported enclosure with an 8” driver suits a small room or desktop-adjacent setup.
Cons: Warranty is a below-average 1 year. The 297.9H x 249.9W x 323.1D mm cabinet and 7.4 kg mass still need deliberate placement.

Dayton Audio SUB-1000L: $209.98 Amazon eBay
Pros: Independent CEA-2010 testing records 89.9 dB at 20 Hz and 110.0 dB through 40-80 Hz. The ported, bottom enclosure with 10” (254mm) 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 152.4H x 635.0W x 400.0D mm cabinet and 12.9 kg mass still need deliberate placement and calibration.
Notes: low profile (<8in)
