The db models have been styled with “tuner” automotive enthusiasts in mind—from the wheel style grilles to the textured driver cones, db says “hot car.” But Polk's db series offers much more than great styling. The full force of Polk Audio’s award-winning engineering went into developing high performance to match the cosmetics. All of the components in the db Series benefit from Polk’s Dynamic Balance technology that stems from a joint research project between Johns Hopkins University's Center for Non Destructive Evaluation and Polk Audio.
The new db Series has been built tough to withstand the rigors of exposure to the sun, water and salt to earn Marine Certified status. db Series speakers are perfect for use in boats of all types.

I have had four systems all having 10s or 12s pushing atleast 500 watts rms per sub.... and I was so impressed with how deep and loud these can hit they are in no way near my Two P3 Rockford 12s but they hit good base notes with out being overwellming. Right now thes 8s are being used with a Kenwood KAC-7205 and they work great to geather in custom sealed boxes in the back of my 300zx z32... I was hopeing for just a little more from these but they are great for the price and well worth buying!

This little sub doesn't require a lot of power and sounds awesome. I have used this sub in outdoor applications. The latest was a golf cart paired with an MB Quart Marine amp and two Polk Audio 5.25". The setup sounds amazing. I would definitely recommend this sub. It's not over powering but just right and it comes at a great price.

This item is very cost effective and has great sound depth and speed. I would choose 8" over 10" or 12" any day because or their performance. Added to that, it is dual voice coil which that in itself makes it better.
