Short answer: the Edifier T5s. It ranks #2 of 73 subwoofers by sound quality, rated 3.8/5, at $199.99; the PreSonus Eris Sub 8BT ranks #13, rated 3.6/5, and costs $209.99, so there is not much of a tradeoff to weigh.
The case for the Edifier T5s: An affordable ported 8 inch subwoofer with strong output for its size, a good bass upgrade for a small to mid size room. Watch for: The 400.0H x 398.8W x 169.9D mm cabinet and 22.9 lbs (10.4 kg) mass still need deliberate placement and calibration.
Why pick the PreSonus Eris Sub 8BT: An affordable, light ported 8 inch subwoofer sized for a small room or a desktop studio setup. The tradeoff: Warranty is a below-average 1 year.
Buy the Edifier T5s. It is rated higher for sound quality than the PreSonus Eris Sub 8BT and costs less, which makes it the one to get unless you need something the other one does better.
