Review: Amazing Sound - 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.
Review: Poor sound - 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.
