Additionally, the built-in crossover control lets you set the frequency at which the subwoofer operates. This feature is particularly useful when pairing it with satellite speakers, ensuring a smooth transition across frequencies.

We found that these tuning options really enhance the overall listening experience. Being able to customize the sound to fit your preferences or room characteristics is a big plus.
