Old cabinet designs: particle board, hardwoodDamage said:That's a pretty bold statement. Considering there hasn't been a scientific improvement in any of those areas except cone materials. And that is debatable based on opinions of sound.
Crossover phasing used to be done by hand ... now they just use computers.
New cabinet designs: MDF, slate, plastics, CAD/CAM design
Old cones: paper
New cones: doped paper, carbon fiber, fiberglass reinforced paper, polyethylene
Old crossover designs: tables, trial and error
New crossover designs: computer precision
Old crossover components: electrolytic caps, carbon resistors, wirewound resistors
New crossover components: polypropylene, mylar caps; metal film resistors
Old tweeter design: paper cones
New tweeter design: plastic, silk, metal, ceramic, metal-vapor-deposit domes, EMIT, plasma, piezoelectric units
Old magnet composition: AlNiCo springs to mind
New magnet composition: rare-earth types such as neodymium.
To me, any component -- not just speakers -- is "vintage" if it was made in 1980 or earlier. This means that yes, I was referring to 60s-70's speakers only. That also means that in the AudioKarma context, only two of my components -- amplifier and turntable -- qualify as being "vintage".But then I consider 80s-early 90s speakers Vintage. Maybe you just meant 60s - 70s speakers only. Which still leaves only materials once again as the only real improvement.
