Short answer: the PreSonus Eris Sub 8BT. It ranks #13 of 73 subwoofers by sound quality, rated 3.6/5, at $209.99; the Dayton Audio SUB-1000L ranks #26, 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: An affordable, light ported 8 inch subwoofer sized for a small room or a desktop studio setup. Watch for: Warranty is a below-average 1 year.
Why pick the Dayton Audio SUB-1000L: A budget low profile 10 inch subwoofer only 15 cm tall, made to slide under a couch or bed. 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.
