Pros: There's no denying this is a world-class speaker.Polk Audio speakers have a very long tradition of quality, and it's immediately apparent as soon as you pick one up.The speakers we review here (DB and AA series) come in various shapes,sizes,and performance and they produce an excellent sound quality.With any luck you'll find something that meets your needs and fits your vehicle.
Cons: There aren't a lot of cons here. However, while the sound is excellent, it doesn't live up to some of our favorite high-end speakers. It also has the occasional tendency to distort at high volume levels.These make fantastic OEM replacement speakers.

General Thoughts on Polk Audio Speakers

We’ve come to really like Polk speakers.We’ve found that they are of a much more consistently good quality than their other products. One thing we have noticed across the board with Polk speakers,is their stylish look.They feature stainless steel mounting hardware and tough-looking ABS grilles with brushed aluminum look finish that will add stylish touch to your car’s interior making it look as good as it sounds.For the price, we believe Polk is a great brand to try.Their speakers are reasonably priced and they make a great option for beginners and audiophiles alike.Note that Polk Audio db Series speakers are  certified for marine use, so they are perfect for use in boats of all types.Moreover,when Correct Craft offers Polk speakers in their award-winning Nautiques ski and wakeboarding boats,you can’t simply ignore the fact that they’re great.

We included a few different options for you fellas. We realize that you guys have different vehicles, preferences, etc. So, please have a look at our recommendations from Polk Audio.

One thing to note with this, is the quality of sound you experience in your car will increase with the quality of speakers you buy.Speakers built with cheap materials will not deliver the highest quality and will not be able to withstand regular and sustained use in the longer term.Whereas, high-end speakers will truly breathe a new life into your sound system while ensuring reliability and performance.

So how do Polk’s car speakers measure up?

Polk Audio DB6501 reviewThe Polk Audio DB6501 is going to be the most expensive pick of the lot by far.If you have read some of our reviews of component speakers,you will know why.You truly get an impressive sound with this type of speakers.They are made to last.

Polk’s versatile db6501 component speaker system features 6-1/2″ woofer made from a polymer/mica composite for big sound with little distortion , as well as durable rubber surrounds that are age proof and allow high cone deflection to facilitate the delivery of higher quality bass and to withstand extreme temperatures and sunlight for long-lasting use.Furthermore,this two-way component system features 25mm liquid-cooled silk/polymer dome tweeters with Neodymium magnets for clear, detailed and sharp highs,immersing you in a pleasurable atmosphere.With the included swivel-mount cups you’ll be able to either surface or flush-mount your tweeters.Whichever approach you decide to take,just make sure you pivot your tweeters so they broadcast towards you for improved stereo imaging.

These speakers fit perfectly into the OEM locations and give crisps and accurate sound reproduction while maintaining your car’s interior appearance.The supplied mounting brackets enable the db6501 to fit both 6 1/2-inch and 6 3/4-inch openings, ensuring an easy and smooth installation process in everything from domestics to imports such as VWs,Audis,BMWs and other European imports.

External crossovers send your speakers and tweeters the frequencies they’re best equipped to handle , which results in efficient, yet accurate sound that will amaze you.Their housings on the other side let you hide all wiring for a clean, professional look.

  • Power Handling
    •  RMS : 60 Watts

Polk Audio DB651 reviewThis is a similar product to the previous speakers we have reviewed. However, you are forfeiting a bit by going with these speakers rather than the others (I mean, it is less than $50). The main difference is these speakers are coaxial while the others are components.Although some people enjoy the sound delivered by coaxial speakers, most and especially trendy audiophiles prefer bright musical detail delivered by component speakers.

If you aren’t willing to plop down some serious cash on a set of component speakers, but you still want a brand name and decent quality product, this set of coaxial speakers should suffice.

This set of speakers can be ordered in two configurations: the standard and the slim configuration. And that’s what we love most about it.Polk Audio db651s is 2-way shallow-mount car speakers set that comes with a new slim mount design and a short tweeter post for an easy fit behind ABS mascular grilles.

Like all Polk db Series speakers,the DB651 and DB651s are built with high quality materials and a level of craftsmanship seldom matched.Their polymer/mica composite mineral filled cone is stiff yet lightweight allowing big and distortion-free sound.The pole plate heat sink on the other hand promotes better heat dissipation for maximum cooling performance and reliability.Additionally,the included multi-hole mounting brackets make for an easy drop-in installations in practically any car on the road.As we’ve said before Polk db Series speakers are built tough to withstand the harshest environments,so they are perfect for use in boats of all types.

The built-in two-way crossovers direct the right frequencies to the proper drivers for seamless, efficient audio and accurate sound.

Polk Audio DB691

  • Size : 6×9
  • Overall Frequency Response : 35Hz-22kHz
  • Nominal Impedance : 4 Ohms
  • Power Handling
    • RMS : 100 Watts
    • Peak :  300 Watts
  • Sensitivity : 93 dB
  • Warranty : 1 year

Polk Audio DB691 reviewThis 3-Way Speakers coaxial speaker system is a truly versatile high-performance coaxial loudspeaker that comes with all Polk features and technology that make it a great choice for any vehicle.It doesn’t quite hold the quality of sound as a component system, but it is certainly a step up from your factory speakers.However,you are still getting a set of speakers that will revitalize your music.We have come across a ton of you who have tried and loved this set of speakers,and for the price,this was an incredible buy.It is a great replacement for factory speakers.It also includes a stainless steel mounting hardware and muscular ABS grilles that will add a stylish touch to your car’s interior.

If you’re on the lookout for the best 6X9 car speakers,look no more than DB691.Its just-right frequency range,along with a high RMS continuous power handling of any type of 6×9 speakers that we’ve reviewed,make the db691 a great buy.Additionally,its four-ohm impedance grants you more flexibility in terms of wiring your sound system.Its two built-in tweeters on the other hand handle high frequencies ,while the main driver covers lower frequencies reproduction (bass), stretching the frequency response down to an impressive low level which is usually covered by subwoofers.
