Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality, rated 4.1/5, at $499.99; the Arendal 1723 Subwoofer 1S ranks #35, rated 3.9/5, and costs $1,650, so there is little reason to consider the other one.
The case for the Monoprice SW-15: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. The catch: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
Why pick the Arendal 1723 Subwoofer 1S: A sealed subwoofer with tight, precise bass, strong output, and app control with parametric EQ for room tuning. Watch for: The sealed design compresses below 40Hz at high output and gives up deep bass to the ported Arendal 1723 Subwoofer 1V, which has far more output between 16 and 40Hz.
Buy the Monoprice SW-15. It is rated higher for sound quality than the Arendal 1723 Subwoofer 1S and costs less, so only choose the other one for a particular feature it does better.
