Certainly productability falls into place with the mass produced garbage, I was however, speaking of higher end speaker drivers than you. If you've heard some of the better hand-built/hand-made speakers, such as the ATD drivers from Italy, you would not be making such statements. I listen to everything from Blue-Grass to Country, Jazz to Classical, and Folk. I don't need different speakers to give me the large orchestra sound at high volume. These are the same speakers that will play a simple solo guitar/folk vocalist perfectly.
This is my point: Many are not aware of the better drivers out there, so they have no idea of what is being missed.
My definition of improved DOES refer to sound quality.
