Best Overall: Polk Audio PSW10

Supported by a lone 10-inch subwoofer and a built-in high current amplifier for big bass, the Polk Audio PSW10 is the very best subwoofer under $100. The 10-inch polymer-composite dynamic balance cone driver is designed to be distortion-free while offering the ideal volume for listening to dialogue whether in an action movie or the nightly news. Its unique configuration is specially tuned to maximize bass production for a powerful sound and the superior compression circuitry assists in removing distortion even at maximum volume levels. With speaker-level inputs and outputs, the Polk is easily connected to nearly any speaker system (although it blends best with other Polk speakers). Measuring 14 x 16.13 x 14.38 inches and weighing 26 pounds, the Polk can easily sit on a shelf, in a corner or on an entertainment center.

Best for Smaller Spaces: Acoustic Audio PSW-6

Ideal for smaller rooms, the Acoustic Audio PSW-6 subwoofer is a great choice for ensuring you have quality sound in your smaller space. The 6.5-inch, down-firing, long-throw subwoofer and its built-in digital drive amplifier push out 250 watts of dynamic power. This makes it ideal for watching sporting events or binging Netflix on the couch, especially when integrated into a larger home theater system. Ultimately, the PSW-6 adds full-bodied bass that’s just soft enough to not disturb the neighbors, with low- and speaker-level inputs for easy connection. It measures 11 x 9 x 10 inches in size and weighs 18 pounds.

Best for Home Theaters: Acoustic Audio PSW-8

Acoustic Audio’s PSW-8 300-watt, eight-inch, down-firing subwoofer is exactly what you want if you’re looking for a budget subwoofer to power a home theater system. With a high-efficiency amplifier built-in and a frequency response between 26 to 250Hz, the PSW-8 offers a full-bodied bass sound that’s good enough to make you watch at least one extra episode of your favorite Netflix show every time.

The black ash finish won’t win any design awards, but it quickly blends into the background allowing the focus to be completely on the sound, not the looks. The eight-inch woofer adds a long excursion cone for a deeper and more accurate bass response, which is exactly what you want for heart-pumping fast-paced action movies and sports. And the high and low inputs let it connect to any amplifier or receiver.

Best Design: Theater Solutions SUB8SM Slim Subwoofer

The Theater Solutions SUB8SM is a breath of fresh air among subwoofers. It has a unique mahogany MDF-enclosed design and a slim build that makes it look more like an old school recorder than the black, boxy subwoofers on this list. It's just 4.75 inches high, allowing it to fit under most furniture, on TV consoles, or just generally tucked out of the way. Despite the small size, it has 250 watts of peak power and a frequency response of 35Hz-150Hz. There are a number of control knobs to control frequency, gain control, and there's a built-in auto-shutoff. The subwoofer can work with home theater systems, surround sound systems, and multiple room systems, and the best part is it fits in with your decor while doing it.
