The Ergo AS 650 SC subwoofer represents the most significantly changed model in the new lineup. Its 12-inch high excursion driver is the first Aluminum cone the company has ever developed for use in a subwoofer. The woofer features dramatically extended excursion capacity thanks to improved suspension, motor assembly, and a new sinusoidal surround.

To make full use of these capabilities, it employs a powerful ICEpower® digital amplifier capable of producing over 350 Watts of power. These improvements all add up to an increase in deep bass output of 6-9 dB and a low frequency extension to the very bottom of the audible range.
