I purchased these to replace a set of $60 Pioneer speakers on my rear deck. The difference in sound quality is impressive.

The MMs have a much warmer, and yet clearer sound than the Pioneers. In my opinion they also blow the Polk Db series out of the water. The separate "tweeter/round mid" design, is far superior to the elliptical design. You get what you pay for!

I am using a simple 4*16 Watts RMS Single Din Alpine Head unit to power all my speakers. While an amp would obviously be better, this unit has more than enough power to drive these speakers.

I matched the rear MM461p, with a set of MM5251 components in the front. I just wished I could have fit some MM6501s in the front door panels, to get slightly more front mid-bass, since I don't have a Sub!

The MM series speakers are in my opinion some of the best mid-priced speakers Polk has ever made.

Unlike Infinity or even Mb Quart speakers, all Polk MMs offer a very warm sound (lower frequencies), therefore not having a sub is not the end of the world!

I was so happy with these, that I installed MM6501s (Front) and MM651s (Rear) in my other car!
