Nice little sub
I built a custom box for this sub under the floor in my hatch by the spare tire - pretty much .35 cu ft. I went with this woofer due to my positive experience with polk component speakers and it's super shallow mounting depth. It seemed to lack low lows until broken in but now I just can't say how impressed I am with an 8" woof. I have my amp bridged at 300 watt rms and the woof seems to do fine even though it is rated at 180 watts. For reference, I've got an equalizer built in to my head unit and a 40 Hz bass boost on my amp that might really be helping me dial in the sound. The lows go low enough and the high/mid bass is more pronounced. It is a quality sound not a boomy sound. That said, if you are looking to wake the neighbors from 2 blocks away, get a couple of 10's or 12's.

Outstanding performance
Product was far better than the original stock woofer that it replaced, and has been solid as a rock since I installed it. Sounds great!

Great 8
This sub is perfect for anyone wantin some added bass, its got a low price point and its reasonably shallow so it wont take up too much room. Polk is a reliable brand in my opinion also.

Excellent value, quality and sound
Added the Polk db840 to my golf cart sound system in conjunction with a pair of the Polk db651s. Sound from the db840 is awesome. Nice clean lows.

Awesome Polk Speakers
These are great sounding speakers and they can really handle the power and still sound great. I installed these on my Polaris RZR 4 and I really do like these speakers.

Good Buy!
6 months and counting. I love the fact that my db840's are marine certified because I have them in my Goldwing motorcycle and they have performed flawlessly. Can't wait to push these babies with the marine amp that I purchase.d from Sonic. The clear vocals and crisp sounds from these speakers should fair well with the 9 in sub that I also purchased from Sonics.

Polk DB 804
I purchased these for some DJ speakers for the mid bass. These sound great and heave very clear sound. I have then wire in series for a 8 ohm load and am pushing 350 watts RMS and these handle it like a champ. The studio amps I am using have a cut off of 100 hz on BI-Amp mode which helps these handle more power than the rating. These are a great deal for the money and do everything I expect of them. I would definitely recommend these If you want quality sound and know what you are doing.
