the reason you won't find FTC power figures on any in-speaker amp is because the FTC does not require it. Please I dare anyone to find a more incorrect place to mount an amp than inside a woofer enclosure? Do you think the money people spend for resonance control on the most expensive stuff out there is for nothing? Wrong if you said yes. have you noticed all the failed built-in sW amps? I wonder if heat, enclosed spaces & vibration are good for heat-generating electronics? Try the Marantz MA-6100, brand new model, I just sold two ($300 list ea) & they sounded as good up to 450 hz as my extremely nice custom amps. 180WRMS real power (not the dynamic music power crap) into 4-ohms. I discount of course.
