These speakers sound wonderful even with just 21 watts (CEA2006 compliant that is.) The highs are sharp, but not harsh and the woofers punish my front doors in my Mazda 3. They aren't even fully broken in yet and this is just with a very reasonable +2 dB on the equalizer set with the 50 Hz curve. I haven't done my rear speakers yet with the Infinity coaxials, but I will be soon. The difference between my old speakers and these is just amazing. The only thing I don't like is the size of the crossover, but quality parts are still worth it.
