the more kilowatts output that much more clearer sound, much, much more clearer. it doesn't mean loader.

also different diameters speakers make different frequency sound better and again clearer.

and this setup definitely much better then your average theater have. also it probably much more expansive and eats probably a megawatts for dinner, lol

PC: btw pay attention to CON like legs on all those tables with speakers and con like lags under speakers them self, pay attention to hard wood floor too, this is everything to make sound not to go right into the ground, this is the most best audio system you will ever see, definitely!!!!
