Love Polk Audio but....
2013 Ford F-150 XLT
I replaced the fronts in my 2013 F50 with some Pioneers that were a little cheaper than the Polk. Both are a good match for the specs ( low wattage factory radio so I went for low RMS with good sensitivity). I got a gift certificate and thought I would use it to replace the rears. Being a long time PA fan thought I might upgrade a little more when doing the rear doors and was excited to order the DB571's. Gotta say these are not in the same class as the Pioneers. A huge response difference. Expected quite a bit more out of the Polks and would trade them in an instant for another pair of the same Pioneers. Better than the factory cheapos but really- not by that much. It could be just this pair I got but yeah, a bummer.
Pros: Price and ease of install
Cons: Muffled sound, less of everything (not just bass) than others in the price range. A let down for a Polk Audio product.
