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.
