Great 8" Sub

Brian from Fayetteville, AR, Sonic Electronix
23 February 2015
  • Conclusion: I have this sub in a sealed .40 cu in box powered by a Kenwood KAS5001PS Mono amp pushing 300W RMS. I have it crossed over at 80Hz with Polk DB651's in the doors with Polk DB461's behind the seats and Polk DB1001 Tweeters all powered to max RMS power, the sound quality is incredible.

Polk DB 804

usmc from redding, ca., Sonic Electronix
24 July 2014
  • Conclusion: 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.

Good Buy!

Cope from Atlanta, Ga, Sonic Electronix

  • Conclusion: 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.

  • Conclusion: 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.
