Invalid - you have a great point. Build that nice flat response speaker and then go add that beast subwoofer so it sounds great but no longer a flat curve on the low end. Then the next poorly EQ recording comes on and you launch over to the sub woofer finger fondling in desperation for the sub volume. Next song, repeat. With the room? O boy, that's a can of worms. I have Nothing against subs, just being a bit sarcastic about not enjoying the music without picking apart musical reproduction when the source may not be as good as the speakers they are played back on. Some recordings sound as good on computer speakers. Do I like accurate music reproduction? Yes, how I perceive it. But my personal goal is to enjoy music and let it move my emotions, stir memories, excitement and admiration for the artists talent. I did the best I believe with the $$ I have. (No concrete speakers here) :)
