Polk AudioDB522 DB+ Series 5-1/4" Coaxial Speaker for Car & Marine, 2-Way Boat & Car Audio Speaker, 55-22kHz Frequency Response, Polypropylene Woofer Cone & 3/4" Silk Dome Tweeter, Easy Installation

I read an article from a car audio reviewer who chose these speakers in a field test against a number of other well known to me car audio manufacturers. I decided to go with the result to replace the four speakers in my 88 Honda Prelude. I decided to go with the original sized speakers, these being 5.25 inch in the two doors and 4 inch Polks in the rear parcel shelf. At the samr time I did add s9me sound deadening on the inside if the door oanels and on the boot floor.The clarity of sound produced by the Polks is simply stunning and I think the best that I have ever experienced. The separation and crossover is amazing. The speakers completely defy their small dimensions. I will have to add a small sub to give the setup some deeper bass, which really is expected and certainly not a criticism as the speakers do provide more bass than expected from speakers of this size, but not quite enough for a fully rounded setup.

These speakers are overrated, ande definitely overpriced.
