About the Polk Audio db351

Leigh Schoettinger
Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk's db351 speakers feature 3-1/2" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 1/2" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.

All db Series speakers feature rustproof baskets and stainless steel mounting hardware. Whether you've got a factory radio or aftermarket stereo, these efficient speakers will spice up your daily drive.

Product Research

Features

Dynamic Balance: Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance. Eliminating resonance in speakers results in a wide, smooth response and low distortion.

Woofer Cones: Each speaker features a Dynamic Balance polymer/mica composite mineral-filled cone. The cones are stiff and lightweight for big sound and low distortion.

Butyl Rubber Surrounds: For a smoother response and improved durability, the woofers use butyl rubber surrounds.

Silk/Polymer Composite Tweeters: The speakers feature 1/2" liquid-cooled silk/polymer composite tweeters for clearer, more accurate highs.

2-way Crossover Network: The built-in 2-way crossover network sends the appropriate frequencies to each driver for cleaner sound and better imaging.

Bass Blockers: The DB351 speakers include two 200 micro-farad capacitors which act as 200 Hz high-pass filters to block bass frequencies from the speakers. These should be installed in-line on the positive (+) speaker lead of each speaker.

Customer Q&A

Q
I have a gen III 2015 Prius with JBL. I understand the best sound is obtained by putting midrange/coax unit in the dash. However, I believe the JBL amp sends a high-pass filtered signal to the dash speaker, so is there any point in putting a midrange in the dash (using the stock JBL amp)?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and help answer your question.

Q
Would these come with free wire harnesses to plug into the stock plugs? Also, how bad are these scratched and/or dented? Warranty included?

When available for your vehicle and mounting location, yes, we'll provide the factory connector harnesses, free of charge, with your purchase of the speakers. The scratch or blemish, if they even have one, will be very small and will not effect the performance or capability of the product in any way. All scratch 7 dent items are covered by the full original manufacturer's warranty. I hope that helps! My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=5
