With dual 10 inch woofers, XRT1K has a more powerful and dynamic bass response than was achievable in prior models. The high-gloss, piano black extruded aluminum enclosure is extra deep to allow top-porting. A new woofer casting permits the XRT1K to have an unusually narrow profile for a loudspeaker with 1,200 Watts of power handling and its 8 Ohm impedance is easy on amplifiers.
