Audio Physic subwoofers are built with the same care and attention to detail as any of their other products. Capable of extending the low frequency response of your speakers by up to 30%, subwoofers are traditionally known as part of a home theater package, but a good subwoofer can also open up music’s midrange frequencies in a properly set up system. When precisely located, a subwoofer that matches the acoustic properties of the other speakers in the system will energize the room, clean up mid-bass distortion, and reinforce acoustic cues can make the midrange sound smoother, less edgy, and more natural.
