Right off the bat, you’ll notice the CA-3550 2.1 stereo speaker system’s distinctly thunderous performance. With a whopping 6.5” subwoofer driver and 2.5” satellite drivers, music and movies sound clear, smooth, and authoritative. Easily accessible main and subwoofer volume control is located right on one of the satellites, so you know everything is in your control. If the CA-3550 is too loud for you, shut them down with the conveniently placed, LED illuminated power button. In audio clarity, the CA-3550 delivers.
