Overview

Our take on the Polk Audio db1040DVC

Polk Audio's db Series subwoofers give you trademark Polk performance without stressing your wallet. These subs combine high-tech materials with a laser-optimized motor structure for smooth, powerful bass response.

Polk Audio's db Series subwoofers give you trademark Polk performance without stressing your wallet. These subs combine high-tech materials with a laser-optimized motor structure for smooth, powerful bass response.

The db1040DVC 10" subwoofer boasts a rigid polypropylene cone and durable Santoprene™ surround built to handle big power over the long run. Polk Audio tests their subs rigorously for environmental effects caused by sun, moisture, and extreme temperature changes.

The dual 4-ohm voice coils allow you to wire your system to draw max power from your mono amp or to safely hook up multiple subs. Match a db sub to a suitable enclosure, and enjoy impressive low-frequency performance rarely found in this price range. And Polk certifies this sub for marine applications, so they're a great choice for your boat too.

Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most 2-channel car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.

To drive this single subwoofer, we recommend a mono amplifier rated between 200 and 400 watts RMS at 2 ohms. For more information, please refer to our article on How to Match Subwoofers and Amplifiers.


Priced per speaker

I bought a set a couple years back for my 97 ram and they still sound new. I decided to buy two more for my 2015 Jeep Wrangler and they sound even more amazing.

Features

Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils that offer flexibility in wiring. When the voice coils are wired in parallel with each other, the woofer presents a 2-ohm mono load. When the voice coils are wired in series with each other, the woofer presents an 8-ohm mono load. In addition, each coil may be connected to a different amplifier channel and each channel will see a 4-ohm load.

Polypropylene Cone: The cone is made with polypropylene, which provides durability while being lightweight and rigid. The cone is supported by a vented cone/coil coupler, which stiffens the cone for greater mechanical stability and lower distortion.

Santoprene Surround: The Santoprene surround is resistant to extremes in temperature, humidity, and exposure to sunlight for excellent long term reliability.

NOMEX Spider: The fire-retardant flat NOMEX Spider allows extended linear motion while providing highly reliable mechanical and thermal stability.

Triple-vented Kapton Voice Coil Former: Triple venting of the 4-layer Kapton Voice Coil Former, Cone/Coil Coupler and Pole Piece contribute to the high power handling and reliability of the db Series subs.

Klippel Laser Analyzed: The Polk db woofer's voice coil alignment, motor, and suspension are optimized using a state-of-the-art Klippel laser analyzer for superior cone travel linearity, resulting in a flatter response with lower distortion.

Break-In Period: Polk db subwoofers will achieve even greater performance once they are thoroughly broken-in. To break in a new db Sub, play music through it for 20 to 30 hours at moderate levels.

Enclosure Compatibility

Recommended Sealed Box Volume: Polk recommends mounting this woofer in a sealed enclosure made out of 3/4" MDF with an internal volume of 0.66 cu/ft.

Recommended Ported Box Volume: Polk recommends a ported enclosure made out of 3/4" MDF with an internal volume of 1.25 cu/ft using a 4" diameter x 12" long port.

Recommended Bandpass Box Volume: Polk recommends a bandpass enclosure made of 3/4" MDF with a total internal volume of 1.65 cu/ft. The bandpass box should have a 0.80 cu/ft sealed rear chamber and a 0.85 cu/ft ported front chamber with 4" diameter x 9" long port.

Why did you buy this?

low cost, good performance, 2 ohm capability [ wilbur  May 31, 2016 ]
Polk Audio always makes quality, dependable products. I trust this brand and have been using their car audio products for more than 20 years. [ George  May 17, 2016 ]
We have dogs that ride in the back, and the rubber surround was a must. Marine rating is a bonus. Also something to consider if you frequently carry things in the trunk. In this price range, this sub has all my expectations for durability and quality. [ Henry  Mar 13, 2016 ]
Adding more low end to Vehicle by adding sub cabinet and amp. Stayed with Polk to match with the rest of the installed speakers. [ Jesse  Feb 05, 2016 ]
I install on the side and found Polk is the best sound / value. My speakers are all polk [ FRANK D  Jan 24, 2016 ]
Very cost effective dvc 10 that fits the enclosure i bought almost perfectly. [ Bryan  Dec 29, 2015 ]

For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Jeff  Dec 19, 2014 ]  Staff
I am powering with an Alpine MRX-V60 5-channel amp. You can definitely put more power to the sub with a dedicated mono amp, but my space for amps is limited and it does just fine for me. Smooth, clean sound in a sealed box. [ Chad  Mar 23, 2014 ]
I'm using a Rockford Fosgate Punch P500-1bd. It's a 500 watt 1 ohm amp wired to two subs in parallel. When I bought my subs the advisor said my amp was a little under power for what they could handle, but it seems to push them pretty well. I have no complaints. [ MICHAEL  Mar 22, 2014 ]
