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.

5.0 out of 5 stars Absolutely worth the money
By Joeydrumplayer on January 2, 2019
High quality speakers that sound great even when not amped. Honestly, these will be hard to beat for the money. Polks tend to be “bright” and there’s no exception here. I found myself frequently lowering the volume due to ear fatigue but I’m sure an amplifier would remedy this, at least partially. Anyone with sensitive ears or mild ear damage may want to look for speakers that are on the “warm” side of the spectrum. Overall, Five Stars! I’m not going to fault them because of my own personal sound preferences. The above is just something to be aware of.

5.0 out of 5 stars Works like a gem.
Reviewed in India on July 27, 2019
After use of close to one month, I am very happy with these speakers. Bought two pairs for my Wagonr Stingray and coupled them with my Sony XAV AX5000. The output quality was truly polk like, Clarity was impressive and they produce decent mid bass as well. To increase the mid base, I used waterproof speaker adapetrs as well. So far so good, and I am quite happy with the experience.
Note: I am not using any additional amplifiers.
