Actually just about every speaker has some plastic or other in it.
Polypropylene is one of the best materials (by itself or mixed with other
materials) for midranges and woofers. Paper, as you probably know, is too
flimsy. Graphite/resin composites were tried for a while but they were too
heavy. My speakers are JL Audio VR690-TX 6x9s, which were the biggest
speakers I could get that would fit in my Sentra's rear deck. They have
mineral-filled (I'm guessing this means silica) polypropylene woofers, mylar
(plastic again) midranges and a fabric dome tweeter. Oh yeah...crossover
caps are usually mylar, which is, as you guessed, plastic.
Even though these are only being driven by a wimpy Coustic 40-watt (at best)
amp, they rock. The combination of lightness and extreme stiffness achieved
by the polypro woofer completely wipes out any distortion you normally
associate with 6x9s. If you don't want to sacrifice your trunk and also
don't want to redesign your trunk springs, a slightly raised deck in the
rear and some stout 6x9s will give you nice results.
Oh, and those lovely surrounds? Plastic.
And most of the insides of a Sentra? Plastic.
I'm not defending Sony. Their head units are very nice; their speaks I
don't care for. But it's not the plastic, it's the engineering.

I just can't bring myself to trust plastic speakers....and in my opinion
sony
should have stuck to home stereo. Sorry if I offended anyone. Not my
intention.
