Polk Audio's db Series

Polk Audio's entire db line of coaxial and component speakers has been redesigned and re-engineered with superior looks and even better sound. Polk has added three new sizes to cover a broader range of vehicle applications. And they've done all that at prices that make high performance affordable to everyone! The db Series works well in OEM factory systems, as well as with high-powered aftermarket head units and component power amps. The db Series delivers classic Polk Audio performance and durability like never before.

This is how you turn up the style.
The look is about more than performance. It's about making every detail count, from the wiring harness under the hood to the fit and finish of your loudspeaker installs. Even before you fire them up, the db Series delivers. ABS wheel-inspired grilles make a muscular statement about your entire audio system and say you're ready to unleash some real sound. Hidden wire channels give your system a clean, professional look. Now if you'd prefer to be more subtle about your audio system (although why would you?), db makes a comfortable stealth installation and will mount easily behind factory grilles.

The db Series fits. Yes, it's just that simple.
The last thing Polk wants is to sell you a great speaker that doesn't fit. Our new multi-hole mounting pattern and shallow-depth magnet design have created our highest vehicle application ratio for easy drop-in installations in just about any car on the road (and probably some that should have been taken off the road years ago). Tweeters in the component models can be flush & surface-swivel mounted using the supplied hardware. With db, we've made sure you have maximum install flexibility.

High Efficiency Design
It means less amplifier power is needed for more audio output. Meaning better sound and more volume using less power. The bottom line is db Loudspeakers will definitely blow you and your friends away, whether they're driven by aftermarket head units or factory installed electronics.

Marine Certified
Marine Certified means your db loudspeakers will perform reliably on the water as well as they do on land. So Polk attacked every db speaker with a series of punishing real world and accelerated weathering lab tests to see if they could take what some pretty nasty marine and automotive environments could dish out. Polk exposed dbs to hundreds of hours of salt fog, intense ultraviolet light and extreme temperatures from -40 degrees to 185 degrees F (-40 degrees to 85 degrees C). They performed as well after the tests as before (they didn't look so good). No wonder Correct Craft builds Polk Audio speakers into their award-winning Nautiques ski and wakeboarding boats, and Bullet uses Polk db speakers in their marine "tower" speaker enclosures.

Just installed these today in my 1990 4runner in the front doors and bought speaker spacers wich were not required. Hooked them up to a orion cobalt 600.4 amp wow these things bump!! Ive read some reviews saying they have no bass thats crazy! These little things got a lot of bass plus highs and mids! Maybe the past reviewers were not putting enogh power to them. I also have a new pair of boston acoustic 6/9 these things blow them out of the water in every way! So time to get rid of those and get another pair of these! Get these you will be happy!! Cant wait to hear how they sound in a month after a full break in period!!
Update Sep 29 09 Just had another pair installed in the back and all I have to say is WOW!! Like I said before I had Boston Acoustic 6/9 s95 in boxes and they just cannot hang with these! You can get away without a sub with these! Love em!

I bought these to replace speakers in a Pontiac vibe. I am extremely please with my choice. I also replaced the factory radio because the CD was skipping and hooked these speakers up to a JVC replacement radio. Wow, what a difference. I read several reviews b4 I bought these and would agree with many people that these speakers sparkle with brilliant sound. The replacement was easier than I thought. It was an excellent choice and I would recommend it to anyone.

I purchased a set of four DB651's to replace the factory speakers in my 2004 Nissan Sentra. My intention was to replace the entire factory sound system piece by piece, but once I installed these speakers I realized I didn't need to change out my head unit or add an amp. These speakers sound perfect with the factory HU. I can turn the HU up to maximum volume and the Polk can handle it with no distortion. When I first installed them, I had a raspy popping sound, but I realized the factory subwoofer was still connected. Since disconnecting the Sub the sound has been perfect! These speakers pick up the bass perfectly, so I decided not to add a sub at all. The sound isn't competition quality, but more than what I'll ever need. Perfect full-range speakers for the average listener. Purchasing these speakers saved me a lot of money on replacing the rest of my system. Thanks Polk!! You have a new fan!
