Not true at all. "Paper" tends to denote taking the cheap way out but is in fact a complicated mess of fibers, polymers, resins etc., engineered for light weight (has to react quickly), high rigidity (prevents deformation) and longevity. Paper's been a proven performer for decades - only recently have things like Kevlar and metal cones been introduced, and while they have advantages and disadvantages over paper, they alone do not make a speaker high end by virtue of their properties.
