Arc Audio X2 12D4 12” 4 Ohm Subwoofer Knowing that consumers are hard on products that offer exceptional value, ARC Audio has put a great deal of effort has into ensuring thermal power handling is reference-class at these price points. The thermally conductive voice coil formers and advanced cooling technologies allow the X2 10 subwoofers to handle 200 watts and the X2 12 to handle 250 watts of continuous power for more than 10 hours. ARC Audio’s new power testing process involves doubling-down the test power levels after each successful round to ensure we know where the weakest links are and have addressed them to the best of our abilities.
