Like the rest of B&W's amplifiers, the ASW 10CM comes with line in and speaker level in inputs. It has only one choice of color: gloss black. Unlike the B&W PV1, the B&W ASW 10CM does not have an innovative shape or unique design. What it does have is a decent weight of 34.4 pounds and a reasonable size with a height of 12.8 inches, a width of 12.8 inches, and a depth of 14.3 inches. The subwoofer has a phase switch and an automatic sensor that switches it into standby when not in use.
