My understanding of sensitivity is as follows:
The sensitivity of a speaker is going to dictate how many watts of power you have to input into it to achieve a given level of audio output. If you can get to your comfort level by turning the volume control to say 40% with a high efficiency speaker and let’s say 70% with the low efficiency speaker, generally, you will be introducing more distortion into the music at the 70% volume level. This happens because as you increase the volume and push the amplifier closer to its limits, a thing called "clipping" occurs as the sound wave is chopped off at the top. The amplifier, at its peak, is simply unable to deliver a clean (undistorted) sound wave unless it has what is called dynamic headroom (reserve power that is available when needed). I don’t think the Stang’s amp has this ability. How much of a problem this will be depends upon whether the amp you use can satisfy the demands of the music you will be listening to at the volume you enjoy. If your speaker is rated at 60 watts, your amplifier should, at a minimum, be able to provide at least this amount of power.
I guess the best thing to do is visit a local car audio shop and ask the pros what they think.
What your saying makes sense. Im not a pro. Just an electronics enthusiast. I just think that Randeez has his mind set that his Pioneers will be half as loud. My Alpines are 88db but have a 110rms rating. They are plenty loud. And as grampstang said with efficiency, it is better as my amp pushes them with 125 watts rms. I never push my amp to its limit so that I dont have to see any distortion come into play.

I would agree that with a low power stock output having the most efficient speaker would be beneficial. But in a $60-80 range I think both the Polks and Pioneers should be comparable in performance. Let us know how it sounds when you put them in. U have them on order regardless.
