My Xtant has an output of about 150 watts RMS @ 2 ohm stereo to my front stage. My chameleons are rated at 100 watts rms, but they seem to take the power without breaking a sweat. I must say that anything even close to full volume is far too loud for my tastes. My sub channel puts out around 300 watts rms @ 2ohms which is balanced very nicely in my setup. At 600 watts of total power, it can get pretty loud.
