Pioneer TS-D690R Coaxial Car Speaker

Pros: Great sound and power handling.
Cons: Slightly larger than factory cutout.

I purchased these along with a pair of Infinity Kappa 42.5i's, both running from my Pioneer DEH-P650 ...

Pros: Handles ton of power, great specs
Cons: Tweeter sticks out too much for some applications

A very good speaker for the money! They handle the bass well, and don't necessarily need an amp to sound good (although one really helps!). They can handle a lot of power, and you know with the built-in crossover that you won't fry the tweeters with any bass!

My only beef with the speaker is that the tweeter is mounted a little high, and may be a problem if you're confined in space. Other than that, it's a great speaker for a great price!
