Big sounds for a great price!
Installed this pair of speakers in a Goldwing motorcycle stereo upgrade. After using these speakers now for over 6 months, I don't think you can purchase a better value for waterproof speakers with the clarity and harmonics of the Polk Audio 501's.

I had to replace some blown Nokia speakers. The remaining Nokias sounded tinny. The addition of these two in the back gives depth and clarity to the music. Now, I can hear the locations of the individual instruments. Plan to buy another pair to replace the remaining nokias.

Bought these for my Honda Goldwing motorcycle to replace the originals. Turns out the ones in the bike had some aftermarket speakers already in it. These sound so much better with better volume than the previous "upgrades." This was a great price on these as well. Would highly recommend them.

I would like to say that these speakers are great. I installed them on my motorcycle, 1999 Honda Valkyrie Interstate. I bought four and I am very pleased with the sound. Had to do just a little modification on each speaker, but I feel that anyone could do it also. I also bought a power amp but have not installed it yet. Waiting for winter. I would recommend these speakers.

The Polk Audio db501 definately exceeded my expectations and offered a significant step up from my factory 4 inch speakers. I can turn up the volume without worry of distortion and they have adequate bass for such small speakers. Good speakers!

Very Good Product
I used the Polk DB501's on my motorcycle and I'm very happy with the results. The improved clarity, combined with higher volume at highway speeds are a big improvement over the OEM speakers.
Good Product ... Good Value.
