This is a remarkably full-featured subwoofer that performs very well in small- to medium-sized rooms. A pair of Defiance V10s can be had for the price of a slightly larger subwoofer, but will provide a more even output at different listening positions than a single subwoofer.
The Defiance series has a variety of options to fit the needs of different scenarios. The V12 model is very similar to the V10 reviewed, here but with a larger, 12-inch woofer. The V8 model, yep, you guessed it, has an eight-inch woofer but also lacks many of the features found in the rest of the Defiance line, including app control, Anthem Room Control, and the ability to add wireless signal transmission. If you decide your budget can stretch a bit, the Defiance “X” series offers more power and refinement with a similar feature set.”
