Polk Audio DB522 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.

Put in the rear of my ford falcon wagon. Very very good sound upgrade for the price. Sounds better than The SCA range at this price point. Powered fine by the stock head unit.

Excellent clear bassy sounds from this speakers

Diese Lautsprecher sind einfach top. Super Klang.

I installed this ones on my motorcycle fairing, and they are loud ,and the sound is clear as well ,of course it depends on your set up . I have amplifer 400w kenwood and JVC deck .

Buena potencia, y calidad de audio en mi caso hubo que ajustar bien la ecualizacion del estéreo y sonará muy bien
