Short answer: the Aperion Audio Bravus 10D, if you are buying new, though neither ranks well in its class. The Sunfire Atmos measures as well as it (#143 vs #142 of 145 subwoofers, 2.9/5 vs 2.9/5) but is discontinued, so only consider it used; the Aperion Audio Bravus 10D is still sold new at $699. Both are rated below 3.0/5 among the 145 subwoofers, so if sound quality matters, consider the Monoprice SW-12 instead, ranked #5 at $266.37.

What the Aperion Audio Bravus 10D does well: 10-inch dual passive radiators with 500W amp deliver surprising output.
Why pick the Sunfire Atmos: 6.5-inch passive radiator reaches 101.6dB CEA-2010-A average for minimal cabinet size.
Buy the Aperion Audio Bravus 10D if you want one new; the Sunfire Atmos is discontinued, so only look for it used.
