Polk Audio DB521-5.25 speakers
These are a direct replacement for the OEM speakers on my '14 Kawasaki Vulcan Voyager, I'm happy with quality and the price. Lil hard to listen to at highway speeds but I knew that when I bought them. They were worth the effort to install.

polk db521 poor quality
For the money they sound great. A+++**edited** one speaker quit working after 3 weeks. I found a capacitor broken off. i re-soldered it and now it seems to work. I shouldn't have to repair a speaker after 3 rides

Best damn marine speakers
This is my 5th pair of Polk DB series speakers and I absolutely love them. They sound awesome with my JBL amp and I cannot be happier with them. Liked them so much that I decided to put them in my Miata.

Great quality
Great speakers and an awesome improvement over the speakers I replaced on my RV exterior. For a 5.25 speaker, they really perform well.

Replacement speakers for my TJ
Bought these speakers to replace my rear speakers in my jeep TJ. They are loud and crisp with factory radio and I’m pleased so far.I was able to use stoke speaker grills to conceal them as I didn’t want to draw attention since I have the top off all summer.

One out of the pair is defective.
They sounded great for about an hour, now one speaker out of the pair pops when you adjust the volume.

excellent jeep speakers
great all-weather speakers for a jeep or open top vehicle. This is my 3rd pair. And yes, I have blown them, but it's taken a lot of effort to do so. Last for quite some time.
