Sound good

The following review is for DB402, which is a part of the bundle you are viewing.

These speakers sound pretty good on my Electra glide. They are not as loud as I would like, but they are louder than I expected. Pretty good sound for only 4".

Polk Audio DB 402

The following review is for DB402, which is a part of the bundle you are viewing.

Bought these speakers to replace Merrill speakers that kept shorting out they didn't last a year. I was blown away by the sound quality of these over the Merrill and these were about 20 dollars cheaper, they are now a year old and sound as good as when I bought them.
I am now a Polk audio fan!
