Pioneer TS-D170R Coaxial Car Speaker

Pros: Affordable, great for Chrysler 6.75" applications!
Cons: Distorts at some lower frequencies

A great speaker! If you were just going to get a 6.5" speaker with an adapter, then you should go with this one! That smidge of surface area gives just a little more bass response, and a slightly higher sensitivity (although that might just be Pioneer playing with specs!). Mine seem to distort just a little with deep, deep bass. Then again, door speakers aren't really meant to do that kind of sound!
